A series of laser modules for the micromachining, optoelectric and industrial laser industries has been released by Quantum Composers Inc. The modules include high-speed shutters, energy attenuators, motorized slit apertures, filter wheels and motorized lens tubes. The shutters complete an open/close cycle in <40 ms and can be used by customers who need to pick off individual pulses of lasers firing at 25 Hz or slower. The motorized energy attenuators can be used to adjust the output energy of multiple or individual wavelengths from 0 to 100% attenuation, with residual energy of blocked wavelengths at 0.25% or less. The slit apertures provide a square beam that controls the X- and Y-axes and theta rotation.
