ir cut filter Optical bandpass filter 650nm 850nm 940nm infrared customizable coated Optical Filters

Laser Mirrors High-quality mirrors for use in laser resonators and other optical devices. The laser cavity contains mirrors and needs to meet some requirements, especially the following: 1. Low reflection loss (for high reflectors) or specified transmittance over a given wavelength range (for output couplers) 2. High surface optical quality (very flat over a large range) (avoid wavefront distortion and thus reduce beam quality) 3. Able to withstand high light intensity, have high damage threshold, and avoid laser-induced damage
