OPSQ-40S06-1-5 40 x 40 mm UVFS Square Optical Parallel Flat Window; t=6 mm Uncoated

The OPSQ-40S06-1-5 is a 40 x 40 mm UVFS Square Optical Parallel Flat Window, featuring a thickness of 6 mm and sourced from the reputable vendor, OptoSigma. This window is a type of flat optical component designed to maintain the direction of an incident light beam while minimizing reflections and dispersion.

The window's base shape is rectangular, with dimensions of 40 mm by 40 mm, providing a substantial surface area for light transmission. The material used for this window is UVFS, which is a type of synthetic fused silica. This material is known for its excellent optical properties, including high transparency, low autofluorescence, and exceptional resistance to thermal shock and chemical attack.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where the natural properties of the material are desired, or where cost considerations are a factor. However, it's important to note that uncoated windows may have higher reflection losses compared to coated ones.

The window is designed to operate at a wavelength of 588 nm, making it suitable for a wide range of applications in the visible light spectrum. Its geometry is that of a thin lens, further enhancing its light transmission capabilities.
