OPB-50C03-P 50 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-50C03-P is a 50 mm diameter N-BK7 round optical parallel flat window with a thickness of 3 mm, manufactured by OptoSigma. This uncoated optical component is designed for use in applications that require a flat window for beam entrance or exit.

The window is made from N-BK7, a popular borosilicate glass known for its excellent optical properties, including a high refractive index and low dispersion. This makes it an ideal choice for a wide range of optical systems, particularly those operating in the visible spectrum.

The flat window design ensures that the wavefront of the light passing through the window remains undistorted, making it suitable for use in imaging systems, interferometers, and other precision optical instruments. The window's thin profile minimizes its impact on the optical path, while its robust construction ensures long-term durability.

The window is uncoated, meaning it does not have any anti-reflective or other surface coatings. This can be advantageous in certain applications where coatings may introduce unwanted reflections or other optical effects. However, it should be noted that uncoated surfaces can reflect up to 4% of incident light, which may need to be taken into account in system design.

The window is available from OptoSigma, a leading manufacturer of optical components. According to the vendor's website, the window is currently in stock, indicating that it is readily available for purchase and delivery.
