PBS1312-780
Conventional polarizing beamsplitter prisms (PBS) generally have a poor extinction ratio in the reflected channel and are unsuitable for applications such as interferometers that impose extinction-ratio requirements on that channel. Through a uniquely optimized coating design, U-optic offers high-performance polarizing beamsplitter prisms with high extinction ratios in both channels.

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.
