47-944 50.0 x 50.0 mm N-BK7 Precision Protective Flat Window; t=4 mm Uncoated

The 47-944 is a 50.0 x 50.0 mm N-BK7 Precision Protective Flat Window with a thickness of 4 mm, sourced from the reputable optical components vendor, Edmund Optics. This uncoated window is designed for use in a variety of optical systems, providing protection while minimizing optical losses.

The window is made from N-BK7, a popular borosilicate crown glass known for its excellent optical properties. It has a refractive index of 1.5168 at 587.6 nm, making it suitable for use in a wide range of wavelengths. The window's rectangular shape, with dimensions of 50.0 x 50.0 mm, provides a large aperture for efficient light transmission.

The window's thickness of 4 mm ensures robustness and durability, while its uncoated surface allows for maximum light transmission without the potential for coating-induced losses. However, it's important to note that the uncoated surface may be more susceptible to environmental contaminants and damage, so handling and cleaning should be done with care.

This window is classified as a flat window, meaning it has no curvature, and is designed to provide protection without altering the optical path. It's ideal for use in applications where optical quality and protection are paramount, such as in laser systems, imaging systems, and optical metrology.
