OPB-50S05-10-5 50 x 50 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-50S05-10-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This square window measures 50 x 50 mm and has a thickness of 5 mm, making it suitable for applications that require a robust and stable optical component.

The window is made from N-BK7, a popular optical glass known for its excellent optical properties. This material, also known as BK7, is renowned for its low dispersion and high homogeneity, making it an ideal choice for a wide range of optical applications. The N-BK7 Schott designation indicates that this particular glass batch comes from the reputable Schott glass manufacturer, ensuring a high level of quality and consistency.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable, as it can simplify the optical design and reduce costs. However, it's important to note that uncoated windows can have higher reflectivity than coated ones, which may need to be considered in the overall optical design.

The window is designed as a flat window, which means its surfaces are parallel to each other. This is crucial in applications where maintaining a consistent optical path length is important, such as in interferometry or beam splitting.

According to the provided data, the window is designed for a wavelength of 588 nm. This makes it suitable for applications that operate in the yellow-orange part of the spectrum, such as certain types of lasers or fluorescence microscopy.
