85-291 25 x 25 x 2 mm UVFS; UV Transmission Grating Beamsplitter; 300 Grooves/mm Uncoated

The 85-291 is a UV Transmission Grating Beamsplitter, sourced from the renowned optical components vendor, Edmund Optics. This grating, measuring 25 x 25 x 2 mm, is designed for use in the ultraviolet (UV) spectrum, offering high transmission rates for UV light.

The grating features 300 grooves per millimeter, providing a high level of dispersion for UV light. The blaze wavelength is 250 nm, indicating the wavelength at which the grating is most efficient. The blaze angle is 8.6 degrees, contributing to the grating's high efficiency.

The grating's orientation vector is (1, 0, 0), meaning it is oriented in the x-direction. The order is -1, indicating the diffraction order of the grating. The grating side is 'Back', suggesting that the grooves are located on the back surface of the grating.

The grating is made from UVFS (UV Fused Silica), a material with a high transmission rate in the UV spectrum. The material ID is 'uvfs mal- 1965', providing a unique identifier for this specific material.

The grating is uncoated, meaning it does not have any additional layers applied to enhance its performance or protect it from environmental factors. This may make it more susceptible to damage, but it also reduces the risk of unwanted reflections or other optical effects caused by coatings.

According to the vendor's website, the grating is in stock, indicating that it is readily available for purchase and delivery. The website also provides a link to further information and specifications for the grating.
