Vortex Optical Coatings have developed processes for manufacturing Infra Red Linear Variable Filters (LVF). An LVF has a coating of wedged thickness, such that the spectral performance continuously changes as one travels along its length. They have been manufactured to cover the following ranges, 900-1700 nm, 1200-2500 nm and 2500nm to 5000nm. This document presents their general properties, the performance of a 900-1700 nm LVF, some applications and comments on producing them in volume.
Quality and precision is a fundamental part of optical component manufacturing and an appropriately specified optic is crucial to get the performance your system requires. The optical surfaces in a system are the main contributors to transmission loss, wavefront errors and aberrations. In addition mechanical specifications can also impact the alignment and stability of an element and consequently the overall system performance.
As point-of-care molecular diagnostics transforms medicine by bringing sophisticated diagnostic testing to the patient, the need for compact optical and detection technologies is increasing. Highly integrated PixelSensor™ multispectral sensors fill this niche well, reducing the complexity, footprint, and cost of OEM instrumentation significantly.
Unlike traditional optical correlation techniques, ASychronous OPtical Sampling (ASOPS) offers a number of advantages in terms of resolution, speed, accuracy and precision. This white paper reports on how the technique of ASOPS can deliver these benefits, with particular emphasis showing the precision available.
In a polarization maintaining (PM) fiber system the quality of a connection plays a crucial role. In order to offer the best overall perfromance, PM fibers must be properly oriented inside the connectors and the alignment features on these must guarantee an appropriate orientation across the mating adapter. Due to different mechanical constructions, not all fibre connectors and mating adapters are suitable for PM applications. The orientation procedures of high-quality PM fibre connectors and the evaluation of their polarisation performance are reviewed according to the current international standards.
