OptoSigma offers the OFSQP-3040R08-20, a rectangular precision polished flat window with dimensions of 30 x 40 mm and a thickness of 8 mm. This window is made of UVFS material with the ID 1965, specifically designed for use at a wavelength of 588 nm.
The OFSQP-3040R08-20 is a flat window, meaning it has no refractive power and is used primarily to protect the optical system or to provide a flat surface for the beam to pass through. The window's rectangular shape allows for efficient use of space and ease of integration into various optical systems.
This particular model is uncoated, which means it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the user does not want to introduce any potential coating aberrations or where cost is a concern. However, it is important to note that uncoated windows may have higher reflectivity than coated windows, which could impact the performance of your optical system.
