OFB-20S05-4 20 x 20 mm N-BK7 Square Precision Ground Flat Window; t=5 mm Uncoated
The OFB-20S05-4 is a high-quality optical window from OptoSigma, designed for precision applications. This window features a base shape of 20 x 20 mm, making it suitable for use in a variety of optical systems. The window is made from N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion.
The OFB-20S05-4 has a thickness of 5 mm, providing robustness and stability in its operation. Despite its thickness, the window is categorized as a 'thin lens', indicating its minimal impact on the optical path. This makes it an ideal choice for applications where minimal distortion is required.
Notably, this window is uncoated, meaning it does not have any anti-reflective or other coatings. While this may result in higher reflective losses, it also means the window can be used in a wider range of wavelengths, making it a versatile option.
