Compact Industrial Housing

The housing ensures the internal optics are free from dust and other contaminants, and eliminates perturbations of the beam due to ambient air conditions; crucial considerations in ultrafast laser applications. A manual shutter and beam dump are included to control the S- and P-polarized output beams.

Manual or Motorized Versions

The VA series of variable attenuators offer either manual or motorized rotation of the waveplate, allowing for continuous variation of the intensity ratio of the two output beams while maintaining all other beam parameters.

Two Prealigned Thin Film Polarizers

Two thin film polarizers are pre-aligned in the housing and optimized for wavelength ranges of 350 - 360 nm, 522 - 542 nm, 780 - 820 nm, or 1034 - 1094 nm. The P-polarized output passes through the first thin film polarizer with negligible beam displacement, while the S-polarized output is reflected off both thin film polarizers and offset in parallel one inch.
