OPB-50S05-1-5 50 x 50 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-50S05-1-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of applications. This square window measures 50 x 50 mm and features a thickness of 5 mm, making it a robust and reliable choice for your optical needs.

The window is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott BK7, offers a high refractive index and low dispersion, making it ideal for use in laser applications and other settings where precise optical control is required.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a natural optical surface is preferred. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust and moisture, so they should be used and stored carefully.

The window's geometry is that of a thin lens, which means it has been precisely shaped to minimize optical aberrations. This makes it suitable for use in high-precision applications where distortion-free optical transmission is crucial.

According to the provided data, the window is designed to operate at a wavelength of 588 nm. This makes it suitable for use with a wide range of light sources, including many types of lasers and LEDs.
