49-634 35.0 x 35.0 mm N-BK7 Precision Protective Flat Window; t=3 mm VIS-NIR 400-1000nm
The 49-634 is a 35.0 x 35.0 mm N-BK7 Precision Protective Flat Window, with a thickness of 3 mm, specifically designed for the visible (VIS) and near-infrared (NIR) spectrum of 400-1000nm. This window is sourced from the renowned optical component vendor, Edmund Optics.
This optical element is classified as a Window, more specifically, a Flat Window, due to its rectangular base shape and thin lens design. The window's dimensions are 35.0 mm in width and length, making it a square window, and 3 mm in thickness, providing robustness and durability.
The window is made of N-BK7, a high-quality borosilicate glass from Schott, which is known for its excellent optical properties, including low autofluorescence, high homogeneity, and excellent transmission in the VIS and NIR ranges. This makes the 49-634 an ideal choice for applications that require high-quality optical transmission and precision.
The window features a coating on both the front and back surfaces, specifically the EDMM VisNIR0SP2002000 coating. This coating is designed to enhance the window's performance in the VIS and NIR ranges, providing improved transmission and protection against environmental factors.
