MKS Instruments has announced the L50(150)A-LP2-35, the newest addition to the Ophir line of LP2 laser power/energy sensors with high damage threshold


Ophir will be displaying the BeamSquared, an M2 laser beam propagation system designed to help users optimise laser performance. A robust, portable device, BeamSquared automatically measures the propagation characteristics of CW and pulsed lasers in less than a minute. It can optionally measure wavelengths above 1.8µm in manual mode, including CO2 and terahertz. BeamSquared is designed for continuous use applications, from scientific research to rapid prototyping, fabrication and machining.

FluxGage - A Photometric Test System for LED Luminaires Based on Solar Panels

This article is brought to you by: 

We present a novel photometric test system for LED luminaires. The new photometric system called 'FluxGage' uses solar panels to detect and measure light. By placing a diffuser and a black pinhole array over a solar panel we achieve a detection surface that is also an absorber. This enables the system to be the same size as the DUT (Device Under Test), as opposed to an integrating sphere, which is at least 3 times larger than the DUT. Simulations and experimental results show that this system can measure total flux with an uncertainty of 4.3%.

Ophir RM9-Thz radiometer

MKS Instruments has announced the Ophir RM9-Thz radiometer, a low noise, high sensitivity sensor for measuring low power levels of 50nW to 100mW from short pulse or CW lasers in the 0.7 to 10THz wavelength range


BeamWatch is the only non-contact beam monitoring system for high power YAG, fibre, and diode lasers used in industrial material processing applications

How is laser Power/Energy measurement affected by incidence angle?

This article is brought to you by: 

Modern laser applications demand ever-increasing accuracy in the measurement and control of the laser beam. Various types of sensors and instruments are in use today, the choice depending on the type of measurement needed. However, even given the correct choice of equipment, there are measurement conditions that can seriously affect the accuracy of the readings obtained if not correctly taken into account.

Ophir Pyro OEM Sensors – What options are available?

This article is brought to you by: 

Pyroelectric sensors have been used widely in the laser industry for many years to measure energy. They allow measurement of individual pulse energy or pulse-to-pulse variation for rapidly pulsing lasers, something that cannot be done with photodiode or thermal sensors. They also are not limited to visible or near-IR wavelengths like photodiodes, allowing measurements into the deep IR and THz regions. Ophir has recently introduced a new series of Pyroelectric OEM sensors based on the “PE-C” line of standard Pyroelectric sensors, which were introduced in 2011. This document presents the various options available to customers, lists the advantages of the new series over existing products, and mentions the capabilities of the new line.

BeamTrack 3A-QUAD

Ophir Photonics has announced its BeamTrack 3A-QUAD, a high sensitivity thermal detector that combines multiple functions, power, energy and position in a single, compact sensor
