SHP1025
High-extinction-ratio linear polarizers are made by cementing a dichroic material between two glass plates. When unpolarized light passes through the polarizer, one orthogonal polarization component is strongly absorbed while the other is absorbed less. These polarizers are commonly used to convert unpolarized light into linearly polarized light with a high extinction ratio. Compared with other polarizing prisms, linear polarizers offer a larger acceptance angle and can be made with larger apertures, but they are unsuitable for high-power applications.

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.
