OPB-20C01-1-5 20 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=1 mm Uncoated

The OPB-20C01-1-5 is a 20 mm diameter N-BK7 round optical parallel flat window with a thickness of 1 mm, uncoated and 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 of N-BK7 Schott, a popular optical glass, known for its excellent optical properties and high transmittance in the visible spectrum. The window has a diameter of 20 mm and a thickness of 1 mm, making it a suitable choice for applications where a thin, lightweight, and durable optical component is required.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it should be noted that uncoated windows can exhibit higher reflectance at the air-glass interfaces, which can be a consideration in high-precision optical systems.

The window is designed to operate at a wavelength of 588 nm, making it suitable for use in a wide range of applications in the visible spectrum. It is currently in stock and available for purchase, with more information available on the OptoSigma website.
