Description: Holographic UV diffusers offer controlled, homogenous light distribution from the UV through the near IR range, with transmission levels of 70% at 190 nm. Salient features: 70% transmission at 190 nm; fused silica substrate; maintains angular control; homogenous light distribution; and two piece aluminium construction. Specifications: material fused - silica; transmission efficiency >= 90% (typical); angle tolerance - ±1o; spectral range - 200 nm to 1500 nm; and temperature range - -40°C to 170°C (-104°F to 338°F). These holographic UV diffusers are offered by Edmund Optics Inc.
