Model 201 Laser Attenuator / Power Splitter:
The Model 201 includes a polarizer which is a GLAN type design with an insertion loss < 4% and an extinction ratio of >100,000:1. In addition, the optics are designed so the angle of the escape port beam is fixed and will not change with wavelength variations. The internal achromatic ½ waveplate is also airspaced to allow for increased power and lower dispersion.
The Model 201 is a valuable tool for MPM and Ti:Sapphire implementations.
