Cemented PBS Prism PBS2015
A polarizing beamsplitter cube separates unpolarized input into orthogonal linear polarizations: P transmits fully and S reflects at 45°, exiting at 90° to P. Two precision UV-fused-silica right-angle prisms are bonded, with a dielectric polarizing coating on one hypotenuse. Any surrounding face can be an entrance, but best polarization performance uses the perpendicular face of the coated prism; a black dot on top identifies it. Laser-line cubes offer Tp:Ts>3000:1. Four transmitting faces have single-wavelength V-type AR coatings with reflection <0.25% at the design wavelength. Ten options are 405, 532, 633, 780, 808, 830, 850, 1030, 1064 and 1550nm.

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.
Driven by the rapid upgrading of intelligent vehicles, optoelectronic sensing technologies represented by laser sensing and infrared thermal imaging have become core pillars for high-level autonomous driving and smart cockpit iteration. Leveraging automotive-grade optoelectronic R&D advantages, Pilot Technology Group launches the VITAL intelligent vehicle solution. By integrating high-power VCSEL laser chips and vehicle infrared night-vision thermal imagers, the system comprehensively enhances vehicle environmental perception and realizes safer, smarter and more comfortable driving experiences.
