WQK7501-AI1 75 mm Dia. N-BK7 Precision Round Window; t=8mm AR 630-1100nm
The WQK7501-AI1 is a high-precision, circular window with a diameter of 75 mm and a thickness of 8 mm. This window is fabricated from N-BK7, a popular borosilicate glass known for its excellent optical properties, including low autofluorescence and high transmittance in the visible spectrum. The window is sourced from Knight Optical, a reputable vendor known for their quality optical components.
This window features an anti-reflective (AR) coating on both the front and back surfaces, designed to minimize reflection and increase transmittance within the 630-1100 nm spectral range. This coating is particularly useful in applications where high transmittance and minimal reflection are critical, such as in laser systems, optical imaging, and beam delivery systems.
The window's geometry is defined as a thin lens, indicating its suitability for use in optical systems where minimal optical power is required. The window's flat design ensures excellent optical quality with low distortion and minimal wavefront aberrations.
