300 Grooves/mm, 8.6° Groove Angle, 25mm Sq, DUV Transmission Grating

Product Details Designed for Deep Ultraviolet (DUV) Wavelengths between 190 – 400nm High Performance in Harsh Environments Multiple Diffraction Angles Available in 12.7 or 25mm Square Sizes 2025 SPIE Prism Award Winning Product Omega Optical DUV Transmission Gratings are designed to extend into the deep UV range, covering 190 – 400nm. Featuring good environmental stability and resistance to solarization, these gratings offer high performance and durability for systems operating in harsh environments. These Gratings provide a diffraction efficiency of 20% for wavelengths greater than 190nm and up to 50% for wavelengths between 200 – 240nm. Omega Optical DUV Transmission Gratings are available in 12.7 and 25mm square construction with resolution ranges from 300 – 1200 grooves/mm. These gratings are ideal for applications that require high-performance solutions, such as semiconductor manufacturing and life science analysis. Handling Gratings: Gratings require special handling and are prone to damage from fingerprints and aerosols. Gratings should only be handled by the edges.
