Ball and Hemispherical Lenses
Ball and hemispherical lenses are polished spherical optical elements made from optical glass, fused silica, sapphire or other optical materials. High transmission suits lasers with antireflection coatings; easy manufacture and light weight make them ideal for optical communications. 同生科技's comprehensive manufacturing/testing equipment supplies quality optics with a full range, advanced technology, good service and reasonable prices. Substrate, size, technical specifications, wavelengths and transmission are selectable/customizable. Ball/hemispherical lenses are offered in varied materials/specifications with excellent UV/IR transmission from 185nm to 2100nm. High-index glass and sapphire hemispheres come in custom sizes with very low spherical aberration across UV–IR.

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.
