49-629 25.0 x 25.0 mm N-BK7 Precision Protective Flat Window; t=4 mm VIS 0 425-675nm

The 49-629 is a 25.0 x 25.0 mm N-BK7 Precision Protective Flat Window with a thickness of 4 mm, specifically designed for the visible light spectrum (VIS) range of 425-675nm. This product is sourced from the renowned optical components vendor, Edmund Optics.

This window is a type of flat window, which is a simple optical component that neither focuses nor deflects light. It is primarily used to protect the more sensitive optical elements in an optical system from dirt, dust, or other environmental contaminants. The window's rectangular base shape, combined with its thin lens shape, ensures easy integration into various optical systems.

The window is made from N-BK7, a high-quality borosilicate glass commonly used in optical systems due to its excellent optical properties. It has a refractive index of approximately 1.5168 at the standard wavelength of 587.6 nm, making it suitable for a wide range of applications.

The window features a standard coating on both the front and back surfaces. This coating, identified as 'edm vis-0 std curve', is designed to optimize the window's performance in the visible light spectrum. The coating status is 'in stock', indicating the product's immediate availability.
