Wedge Optical Windows, Φ25.0mm, Thickness=6.0mm SWIR H-K9L Optical Glass, United Optical Technology Co., Ltd (CAT#: STEM-OP-3078-YJL)

Wedge Optical Windows, Φ25.0mm, Thickness=6.0mm SWIR H-K9L Optical Glass, model 197523, is manufactured by United Optical Technology Co., Ltd.
The two planes of the K9 High Precision Wedge Windows have an included angle of 30 arc minutes. When used in pairs, through the relative rotation of the two optical wedges, the outgoing beam can be positioned in any direction within a pyramid with the incident beam as the axis.
K9 optical glass is an optical material with excellent wide spectrum transmission and high transmittance from 350nm to 2000nm. It has high hardness, can withstand a variety of physical and chemical stimuli, and has low bubble and impurity content. Therefore, it is often used as the substrate for various optical components to make various optical components.

Two non-parallel planes can avoid the interference effect (Etalon effect) caused by the reflected light from the front and rear surfaces of the highly parallel window. At the same time, it can also avoid the optical interference feedback of the laser resonator, which causes poor stability of the laser output, mode jumping, etc.
