OPB-20S05-P 20 x 20 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated
The OPB-20S05-P is a 20 x 20 mm N-BK7 Square Optical Parallel Flat Window, featuring a thickness of 5 mm and manufactured by OptoSigma. This window is a type of flat optical component designed to maintain the direction of an incident light beam while minimizing reflections and distortions.
The window is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high homogeneity. N-BK7 is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal material for various optical applications.
The window has a rectangular base shape with dimensions of 20 x 20 mm, and a thickness of 5 mm, providing robustness and stability. The uncoated surface ensures high transmittance for the central wavelength of 588 nm, making it suitable for applications where anti-reflection coatings are not required.
The window is available from OptoSigma, a leading manufacturer and supplier of high-quality optical components. According to the vendor's website, the item is currently in stock, ensuring quick delivery and availability for immediate use.
