OPB-20C05-1-5 20 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-20C05-1-5 is a 20 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, sourced from OptoSigma. This window is a type of flat window, designed with a base shape of a circle, and features a thin lens shape.

The window is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high refractive index and low dispersion. This makes it an ideal choice for various optical applications that require high-quality performance.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired, or where cost is a significant factor.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications that use this wavelength, such as certain types of lasers or light-based measurement systems.

According to the vendor's website, the window is currently in stock, indicating that it is readily available for purchase and delivery. This can be crucial for users who need to acquire components quickly for their projects or applications.
