The OPB-50C05-P is a 50 mm diameter N-BK7 round optical parallel flat window, with a thickness of 5 mm, sourced from OptoSigma. This uncoated optical component is designed for use in applications that require a flat window for optical systems.
The window is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. It is a crown glass with a low refractive index and low dispersion, making it an ideal choice for various optical applications. The glass is also highly resistant to thermal shock and has a low coefficient of thermal expansion.
The window's geometry is circular, with a diameter of 50 mm and a thickness of 5 mm. This thin lens shape is ideal for applications where minimal interference with the light path is required. The window is uncoated, meaning it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not necessary or desirable.
The window is designed to work at a wavelength of 588 nm, although it can be used in a broader spectral range depending on the specific application. It is currently in stock and available for purchase, as indicated by its valid weblink status.
