VPWW42-C 1.5 in Dia. AR Coated; UVFS Wedged Window; t=4 mm 1050-1700nm

The VPWW42-C is a wedge window with a diameter of 1.5 inches, sourced from the reputable vendor Thorlabs. This particular model is made from UVFS material, identified as UVFS Mal-1965 in the material database. The window features an antireflective (AR) coating on both the front and back surfaces, denoted as 'tho c bbar', which enhances its transmission capabilities across various wavelengths.

The geometry of the VPWW42-C includes a diameter of approximately 38.1 mm, a thickness of 4 mm, and a wedge angle of 0.008726646259971648 radians. This wedge angle, although small, can significantly reduce beam deviation in certain applications. The window is designed to operate within the wavelength range of 1050-1700 nm, making it suitable for near-infrared (NIR) and shortwave infrared (SWIR) applications.
