OPB-15C05-10-5 15 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-15C05-10-5 is a 15 mm diameter, 5 mm thick optical flat window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window, sourced from OptoSigma, is a flat, circular window designed for use in various optical systems where parallel light transmission is required.

The window's geometry is defined by a 15 mm diameter and a thickness of 5 mm, making it suitable for applications that require a balance between light transmission and structural integrity. The N-BK7 material, also known as BK7, is a borosilicate crown glass with a refractive index of approximately 1.5168 at 588 nm, the wavelength provided in the item data.

The window's shape is described as a 'Thin Lens', indicating that it has minimal optical power and is primarily used for light transmission rather than refraction or focusing. The coating parameter is an empty object, suggesting that this particular window is uncoated. Coatings are often applied to optical surfaces to enhance their performance, such as increasing transmission, reducing reflection, or providing environmental protection. However, an uncoated window can be suitable for applications where such enhancements are not necessary.

The item data also provides a 'weblink status' of 'Valid - in stock', indicating that this item is available for purchase and immediate use. The vendor is listed as OptoSigma, a leading manufacturer and supplier of optical components.
