37-071 75.0 x 75.0 mm N-BK7 Precision Protective Flat Window; t=4 mm VIS 0 425-675nm

The 37-071 is a 75.0 x 75.0 mm N-BK7 Precision Protective Flat Window with a thickness of 4 mm, specifically designed for the visible light spectrum between 425-675nm. This window is sourced from the reputable optical vendor, Edmund Optics.

This optical element is classified as a Flat Window, a type of Window that does not alter the wavefront of the incident light. It is rectangular in shape, with a width and length of 75mm each, making it suitable for applications requiring a larger aperture. The window is made from N-BK7, a popular glass type known for its excellent optical properties, including low dispersion and high homogeneity.

The 37-071 is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the window's performance in the visible light spectrum, providing improved transmission and protection against environmental factors. The coating is applied using advanced techniques to ensure uniformity and durability.

The window's geometry is defined as a Thin Lens, indicating that it has a small thickness relative to its diameter. This characteristic contributes to the window's minimal optical power and distortion, making it ideal for applications requiring high-precision optical paths.
