37-074 75.0 x 75.0 mm N-BK7 Precision Protective Flat Window; t=4 mm NIR I 600-1050nm

The 37-074 is a 75.0 x 75.0 mm N-BK7 Precision Protective Flat Window with a thickness of 4 mm, specifically designed for the Near-Infrared (NIR) region of the spectrum, spanning from 600 to 1050nm. This window is sourced from the reputable optical vendor, Edmund Optics.

This optical element is a Flat Window, a type of Window that does not alter the wavefront of the incident light, making it ideal for protective applications where the original quality of the light needs to be preserved. The Base Shape of this Window is Rectangular, providing a larger surface area for light to pass through, which can be beneficial in applications requiring high light transmission.

The Window is made of N-BK7, a high-quality Borosilicate Crown glass, known for its excellent optical properties, including low dispersion and high transmission in the visible and near-infrared regions. This material is identified by the Material ID [n-bk7 schott], ensuring compatibility with other optical elements in your system.

The 37-074 is coated with the EDM NIR-I STD Curve on both the front and back surfaces. This coating enhances the Window's performance in the NIR region, providing improved transmission and protection against environmental factors.

The Shape of this Window is Thin Lens, indicating that it has been precisely manufactured to maintain a consistent thickness across the entire surface. This feature is crucial in applications where uniformity and consistency are paramount.
