WQK2525-AI2 25 x 25 mm N-BK7 Precision Rectangular Window; t=6mm AR 1050-1700nm

This is the WQK2525-AI2, a 25 x 25 mm N-BK7 Precision Rectangular Window with a thickness of 6mm, designed for use in the spectral range of 1050-1700nm. This window is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The window is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties and high damage threshold. The window's rectangular shape, with dimensions of 25 x 25 mm, makes it suitable for a wide range of applications where a larger aperture is required.

The window features an anti-reflection (AR) coating on both the front and back surfaces. This coating is specifically designed for the 1050-1700nm range, ensuring high transmission and low reflection. The AR coating enhances the window's performance in the infrared region, making it ideal for applications such as IR imaging, spectroscopy, and beam delivery systems.

The window's thin lens shape allows for easy integration into optical systems. It is 6mm thick, providing sufficient mechanical strength while minimizing unwanted optical effects such as beam deviation and distortion.
