OPB-30S05-20-2 30 x 30 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-30S05-20-2 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 30 x 30 mm, making it suitable for use in applications where a larger aperture is required.

The window is made from N-BK7, a popular optical glass known for its excellent optical properties. This material, also known as BK7, is a crown glass with a low refractive index and low dispersion, making it an ideal choice for a wide range of optical applications. The window has a thickness of 5 mm, providing a good balance between strength and weight.

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 the cost of additional coatings is a concern. However, it should be noted that uncoated windows can exhibit higher levels of reflection, which may need to be taken into account in the design of the optical system.

The window is available from OptoSigma, a leading supplier 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. The website also provides further technical details and specifications, as well as options for customization and further processing.
