OPB-40S06-10-5 40 x 40 mm N-BK7 Square Optical Parallel Flat Window; t=6 mm Uncoated

The OPB-40S06-10-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This window is rectangular in shape, with dimensions of 40 x 40 mm, making it suitable for use in applications that require a larger aperture. The window has a thickness of 6 mm, providing robustness and stability.

The window is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties. N-BK7 is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for a wide range of optical applications. The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where the natural properties of the glass are desired.

The window is designed to be used at a wavelength of 588 nm, although it can be used at other wavelengths depending on the specific requirements of your application. It is classified as a flat window, indicating that its surfaces are parallel to each other, which is crucial in many optical systems.

The window is currently in stock and available for purchase from the OptoSigma website. With its high-quality materials, robust design, and excellent optical properties, the OPB-40S06-10-5 is an excellent choice for a wide range of optical applications.
