User's Manual
C-mount interface for universal application to our CCD and Pyroelectric cameras 190-380nm attenuation covers Excimer, Helium Cadmium, and the Nd:YAG UV harmonic laser wavelengths. Attenuation with these ND filters permits the best use of the dynamic range of a beam profiling camera. Attenuation range of 0.3 to 6.0 optical densities (ND). Set consists of three slides with two filters in each slide.
The Six Filters include 0.3, 0.7, 1.0, 2.0, 3.0 and 4.0 optical densities. Two filters can be employed at one time for 0.3 – 6.0 optical attenuation in 0.3 or 0.4 ND steps. 20mm clear aperture will not vignette any of our applicable camera sensors. Damage threshold = 100W/cm2 for CW lasers and 20mJ/cm2 for nano-second pulse width lasers. Additional Beam Splitters can be added for attenuation of high power UV lasers. UV attenuation system uses high quality optics from the leader in laser beam diagnostics.
