λ/10 High Precision Wedge Windows
The K9 High Precision Wedge Window has a 30 arc-minute angle between its two planes.
The non-parallel planes help to avoid interference effects caused by the reflection of light from the front and back surfaces of high-parallel windows (Etalon effect).
Additionally, they prevent optical interference feedback in laser resonant cavities, leading to poor laser output stability and mode hopping.

These Wedge Windows are commonly used to deflect incident light beams at a specific angle.
When used in pairs, the relative rotation of the two wedges allows the outgoing light beam to be positioned in any direction within a cone centered on the axis of the incident light beam.
etaOptics can also customize wedge windows with various angles and Anti-reflection coating according to customer requirements.
etaOptics offers uncoated K9 Optical Glass windows and a variety of optical windows covering a wavelength range from Visible (VIS) to Infrared (IR).
- Visible (VIS): 350-700nm
- Near Infrared (NIR): 600-1100nm
- Short-wave Infrared (SWIR): 900-1700nm
