Flood Exposure Source, 1000 W Hg(Xe), 6 x 6 in., ± 2.5°, 260 - 320 nm

The 92532 Flood Exposure Source is a 1000 Watt source for the mid UV (260 - 320 nm) spectral range. MUV is used for polymer cross-linking and novel resists. This source irradiates samples with a 6.0 inch x 6.0 inch (152 mm x 152 mm) illumination area with a ± 2.5° collimation angle. Typical output is 34 mW cm-2. An efficient ellipsoidal reflector, coated with enhanced Rhodium for MUV collects up to 70% of the arc lamp output. A 45° primary dichroic mirror spectrally reflects the light after passing through a proprietary design beam homogenizer. The homogenizer, or optical integrator, is similar to a compound fly's eye. It scrambles the arc lamp's non-uniform irradiance to produce many diverging beams. These diverging beams overlap at the collimating lens to produce a highly uniform, collimated beam at the work plane.
