OPB-20S02-4-5 20 x 20 mm N-BK7 Square Optical Parallel Flat Window; t=2 mm Uncoated

The OPB-20S02-4-5 is a 20 x 20 mm N-BK7 Square Optical Parallel Flat Window, featuring a thickness of 2 mm and uncoated surfaces. This optical window is sourced from OptoSigma, a renowned vendor in the optics industry.

The window is designed in a flat, rectangular shape, with dimensions of 20 x 20 mm, providing a substantial surface area for various optical applications. The thickness of 2 mm ensures durability and rigidity, while maintaining a low profile to minimize optical distortion.

The material of the window is N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum, particularly at the wavelength of 588 nm.

The window is uncoated, meaning it does not have any additional layers of anti-reflective or other coatings. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost-effectiveness is a priority. However, it's important to note that uncoated windows may have higher reflectivity at the air-glass interface, which could impact the performance in some applications.

The window is classified as a 'Thin Lens' in our catalog, indicating its potential use in lens systems. However, its primary function is to provide a clear, flat surface for optical beams to pass through, making it suitable for a wide range of applications, from laser systems to imaging devices.
