24 June 2019 to 27 June 2019
Munich, Germany

Laser World of Photonics, the world's leading trade fair with congress for photonics components, systems and applications. Together with the World of Photonics Congress, the fair unites research and industry and promotes the use and ongoing development in the Photonics industry.

Exhibitors: 

AMS Technologies

AMS Technologies (booth 203, hall B2) will present a diode-pumped solid-state laser that emits very short laser pulses (< 5ns) of high energy (up to 20µJ) with four wavelengths in the visible range. Using sophisticated technology, the Tetra laser can switch from pulse to pulse between these four wavelengths with a very high pulse repetition frequency of 2kHz and is thus 10 times faster than lasers based on OPOs (Optical Parametric Oscillators). With this ability to emit laser pulses in four biologically useful wavelengths in very fast sequence, Tetra is particularly suitable for multispectral photoacoustic imaging in biomedicine.

Avantes

Avantes (booth 100, hall a2) will display several new products, including its new miniature optical bench, made for seamless integration into existing systems and handheld devices with the use of your own electronics.

Another innovation is its new high-power LED light source for demanding fluorescence applications.

In addition to these products, the company will showcase some new accessories, including a direct-attach shutter to make taking multiple dark measurements a lot easier.

Since Avantes celebrated its 25th anniversary this year, the company will be organising some giveaway contests at its booth.

Company: 

Berliner Glas Group

Berliner Glas Group will present its broad portfolio of opto-mechanical assemblies and systems for various light-using industries in hall B1, booth 507. The company will exhibit, optical assemblies for space applications, modules for optical measurement systems, specific lens systems and measurement reflectors for laser based metrology, large cylinder lenses and aspheres as well as laser optics and systems for laser material processing.

As an OEM partner from concept to volume production, Berliner Glas Group serves innovative customers in various market segments – laser and space technology,
semiconductor industry, metrology, medical technology and the display industry. One featured highlight will be a compact, actively controlled lens moving mechanism for beam focusing and demanding z-scanning applications.

Diamond

High power pump lasers using multimode fibres require a low loss fibre optic connector to ensure ultimate performance. The newest PSm mating adapter from Diamond (booth 515, hall b1) is built around a floating Tungsten carbide sleeve, along with copper wings to create a perfect connection between two Diamond E-2000 PSm connectors. The copper wings connect to the heat sink holder when inserted and lower the temperature gradient close to the fiber, improving power resistance of the assembly.

The new mating adapter resists up to 100W when combined with Diamond E-2000 PSm connectors and a MM 105/125 0.22NA fibre.

Tungsten carbide thermal dissipation is ca 50x higher than that of the ceramic materials and ca 5x higher than that of the stainless steel. When used in mating adapters with a micron tolerance, the power dissipation improves dramatically. Diamond is a specialist of hard material and has been using tungsten carbide (WC) for long as a ferrule material and mating adapter sleeve.

Company: 

Emberion

Emberion (hall A2, booth 113/3) will introduce a cost-competitive nanomaterial-based linear array sensor for visible to shortwave infrared spectral range designed primarily for spectrometers. The 512 pixel VIS-SWIR linear array provides consistent responsivity with very low noise over a broad (400-1,800 nm) spectral range in room temperature operation and offers a cost-effective solution for SWIR detection.

The dynamic range of the sensor is very large owing to its low noise and non-saturating response characteristics. The sensor comprises a detector array monolithically built on a tailor-made CMOS readout integrated circuit and it provides digital data output with up to 16 bits resolution.  The sensor is designed primarily for spectrometry applications but other potential applications lie in line scan imaging and machine vision areas. Beyond the linear array product introduced, Emberion will offer VIS-SWIR VGA imagers in 2020 and is also developing thermal detectors. 

Hamamatsu Photonics

Hamamatsu Photonics (hall A2, booth 303) will introduce its latest range of high reliability, key components for lidar applications, such as photosensor arrays including APDs and SiPMs (for all relevant wavelengths e.g. 905nm or 1,550nm). They company will also introduce new high power SMD laser diode arrays specifically designed for automotive lidar. 

Lidar is a key technology for automated driving as well as anti-collision applications today. A LIDAR device makes a time of flight (TOF) measurement using a pulsed light source and detector to determine the distance to objects around the vehicle. 

Visit Hamamatsu Photonics' booth to discover the latest products for lidar and many other applications. 

Hübner Photonics

At booth 214, hall 2, Hübner Photonics, with the Cobolt product line, will highlight the addition of 633nm and 785nm single transverse mode (STM) to its 08-01 series. The addition of these wavelengths aims to secure the market position as a major supplier of all laser wavelengths to the high resolution Raman market.

Continuing to address the fluorescence microscopy market, Hübner Photonics introduces a variation of the Cobolt multi-line laser, the Cobolt Skyra. With 457nm, 488nm and 51nm, permanently aligned in a single compact package, the three line Cobolt Skyra becomes a simple drop in replacement to the older generation of Argon ion gas lasers, thereby potentially extending the life of older fluorescence based systems in life science research.

 

iC-Haus

The new iC-HN device family from iC-Haus is suitable for extremely fast control of laser diodes with short pulses of down to only two nanoseconds. Possible fields of laser applications for the iC-HN family include optical image recognition and object detection, as well as applications in robotics, lidar, and augmented and virtual reality.

Having only eight ports and a small 3mm DFN package, the iC-HN family best meets the requirements for a space-saving and highly integrated layout of laser control electronics.

The permissible supply voltage of the laser diodes can be as high as 30V. The laser driver iC can therefore also be used for a free and flexible circuitry of several or different laser diodes. The current setting of up to 2.8A is generated via a control voltage input, which in turn can be controlled by an LVDS signal with short pulses up to 2ns.

Company: 

Laser Components

With the SPAD2L192, Laser Components now also offers a solid-state CMOS sensor for flash lidar applications. With a resolution of 192 x 2 pixels, the single photon avalanche diode (SPAD) array offers very high sensitivity and high temporal resolution. The noise is below 50cps. The in-pixel time-to-digital converter, which features a temporal resolution of 312.5ps and a scale value of 1.28μs, enables a nominal range of up to 192m at a resolution of 4.7cm. The distance measurement is based on the first-photon, direct ToF principle.

The arrays in flash lidar applications do not capture just one point like they do in classic lidar. Each individual pixel provides position information. In the SPAD array presented here, the sensor and evaluation electronics have been mounted on the same chip for the first time, thus the array takes up very little space.

Lew Techniques

Lew Techniques (hall b2, booth 121) will be showing its capabilities in the precision custom manufacture of submounts and carriers for laser diodes, bars, stacks and photodiodes. 

Product types include tungsten/copper (WCu) submounts with super-sharp edges (<5µm radius), allowing precise mount-edge positioning of laser diodes. WCu inserts brazed to solid copper bodies maximise heat-sinking while minimising expansion mismatch between carrier and die. 

Submounts in aluminium nitride (AlN) with photo-patterned metallisation provide high-precision circuits. Metal structures can be tailored to meet individual requirements for soldering, wire bonding, electrical and thermal performance. 

WCu- and AlN-style mounts selectively coated with a thin layer of AuSn solder allow accurate and consistent mounting of the laser die. Strict maintenance of metal coatings and solder alloy consistency ensure optimum reflow results.

Mounts for photodiodes on ceramics with wrap-over conductors are available. Circuits can be defined on multiple faces allowing greater interconnect flexibility, and ceramic can be precision-machined for greatest functionality.

Company: 

LightPath Technologies

LightPath Technologies (hall b3, booth 362) will be showing its new line of thermal imaging lens assemblies, which includes the new DT/molded BD6 7100353 (35mm) and the 7100383 (50mm). These lenses are made from LightPath’s BD6 glass that delivers optically athermal performance and is suitable for high volume, cost effective manufacturing. 

LightPath leverages a combination of manufacturing technologies – precision glass molding (PGM) and precision diamond turning (DT) – to address both the high-volume growth of the commercial market as well as the demanding performance and reliability of high-end defense applications.  With lens focal lengths ranging from 1.5mm to 60mm, along with custom design capabilities, LightPath Technologies has a lens solution for a broad array of thermal imaging applications.

In addition to its line of thermal imaging lenses, LightPath’s Geltech glass-moulded aspheric lenses and ISP Optics Infrared components will be on display.

LTB Lasertechnik Berlin

The Demon-NIR extends the well-established Demon Echelle Monochromator series providing wavelength ranges from 190nm to 1,100nm and resolving powers of 75,000 to 200,000.

Ophir

Ophir will demonstrate how users can measure critical beam parameters in industrial environments at high power levels with Ophir BeamWatch Integrated. The solution was developed for the use in automated production lines and is based on Ophir’s non-contact laser measurement technology.

BeamWatch Integrated accurately captures and analyses focal spot data of industrial lasers for wavelengths from 980nm to 1,080nm. The system provides real-time measurements of focused laser beams with a power density that is too high for traditional measurement devices. Beam parameters measured in real time include focus spot width and location, focal shift, centroid, M2, divergence, beam parameter product, Rayleigh length, beam tilt angle, and absolute power.

Because there is no contact with the focused beam, there is no wear on the instrument nor does the instrument temper with the measurement, making the system ideal for 24/7 production use. Fast measurement times allow the laser beam to be checked automatically during the loading/unloading phase.

Company: 

Nanoscribe

In Hall a3, booth 325, Nanoscribe, technology leader for 3D printers in the nano- and micrometre range, will present a brand-new printer platform that will advance industrial micro manufacturingmarket.

Company: 

Zemax

Zemax senior optical engineer Zach Derocher will introduce TrueFreeForm, a grid-based surface optimisation of freeform surfaces in optical design, on Monday 24 June, at 11:00-11:20, in hall B2, booth number 356.

Some lens design applications use parametric functions for representing freeform surfaces. Most common perhaps is a linear combination of Zernike functions. There is a downside to parametric approaches, though, namely that optimisation of parameters typically forces the entire surface to change with each variable. In his talk, Derocher speaks about a grid-based surface where sag contributions are specified on a rectangular grid. Optimising on sag described in this fashion allows local influence on a specific region of the surface that is only as wide as twice the grid spacing.

Grid-based surface optimisation in OpticStudio lens design software allows flexibility in designing freeform optical components that is not possible with traditional surface types. The system Zemax focuses on is a corrector plate with the rear surface specified by a variable grid sag surface. The goal of the corrector plate is to correct for Wavefront error introduced by a Zernike phase surface. Derocher will describe the tests and report on findings, including the importance of constraints on the grid variables and techniques that improve the calculation efficiency.
