Precision accuracy is a critical necessity with any optical component. Rigorous testing to ensure strict compliance with given requirements will always be essential; it is a vitally important demand within any industry sector. Dimensional, surface profiling and optical performance testing are significant aspects of this process, but an additional layer of assurance and quality can be achieved with the use of material verification, employing methods such as refractive index, density testing and transmission measurement. This White Paper explores advanced techniques for precise optical material verification, overcoming the limitations of traditional testing methods.

Near infrared optical coherence tomography has traditionally been limited to imaging depths of just a few millimeters, but with our expanded line of OCT spectrometers, up to 12 mm is possible. In this tech note, we explore and compare three different drop-in spectrometer models designed to serve a wide range of resolution, depth, and size requirements in NIR OCT imaging.

Discover our whitepaper, “Impact of Backgrounds on Virtual Image Quality in AR Glasses.” Optical see-through AR promises seamless overlays, yet real-world backgrounds reshape contrast, color, and uniformity of the virtual image. We quantify how luminance, chromaticity, and spatial structure constrain influence the virtual image using calibrated photometric and colorimetric measurements and additive color-mixing analysis. Learn key trade-offs between visibility and transparency – and optimization guidance for AR systems.
