OPB-20S03-1-5 20 x 20 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-20S03-1-5 is a high-quality optical window from OptoSigma, designed for use in a wide range of optical systems. This window is rectangular in shape, with dimensions of 20 x 20 mm, making it suitable for applications that require a larger aperture. The window has a thickness of 3 mm, providing excellent rigidity and durability.

The window is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties. N-BK7 is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for many optical applications. The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable.

The window is designed to be used in parallel optical systems, where it will maintain the collimation of light passing through it. It is in stock and available for immediate purchase, with more information available on the OptoSigma website.
