The attenuator may be adjusted from 0% to 100% with a shutter closure to insure no residual energy at 0% output. An internal calibration and linearization function simplifies setup and calibration. Attenuator modules can be connected together in a daisy chain providing independent control of energy in multiple wavelength systems. Wavelengths 266nm, 355nm, 532nm, & 1064nm Input Beam Height 60mm (other configurations available upon request) Direction Collinear Polarization Linear, any orientation Fluence 2 J/cm2 max Diameter 6.35mm max Output Direction Collinear, 180 degrees to input Displacement – TBD (150mm min) Beam Expander 2x Polarization Linear, S polarized Tmax 266nm = 95% 355nm = 85% 532nm = 75% 1064nm = 70% Extinction 22dB min (150:1) min Purity Residual energy < 0.25% Range 0 to Tmax, linearized, normalized Resolution 0.2% nominal Controller Comm RS232, w/ bypass output, which allows multiply units to be daisy chained on the same serial port. Baud Rate 57,600 (other speeds available on request). Range 0 to 100% Resolution 0.1% Tact Time < 1s, full range motion, for all four wavelengths V1.0
