Glan Thompson Polarizer
Glan-Thompson polarizers consist of two cemented prisms made from the highest optical grade of calcite or a-BBO crystal. Unpolarized light enters the polarizer and is split at the interface between the two crystals. The ordinary rays are reflected at each interface, causing them to be scattered and partially absorbed by the polarizer housing. The extraordinary rays pass straight through the polarizer, providing a polarized output.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.
Founded in Beijing in 2011, Beijing FJR Opto-electronic Technology Co., Ltd. specializes in R&D, manufacturing and sales of infrared thermal imaging equipment and complete optoelectronic systems.
The ElFys PD25s series photodetectors adopt ElFys‑patented Black Silicon Induced Junction technology, delivering excellent spectral response spanning deep‑ultraviolet, visible and near‑infrared bands for diverse high‑precision photometry applications. Sub‑variants including H, M, HG and MG are optimised for low‑capacitance, low‑dark‑current and high‑reverse‑bias guard‑ring operations respectively. Multiple packaging configurations are available to satisfy various system‑design requirements.
Fiber lasers and fiber amplification systems require excitation sources with stable wavelength, narrow spectral linewidth and consistent output power.
