A line of short-pass filters is available from Iridian Spectral Technologies Ltd. The devices include the four laser lines at 514.5, 532, 633 and 785 nm. The passband ripple is ±<2%, and the optical density is >6. The short-pass filters allow access to the anti-Stokes spectrum much closer to the laser line than was previously possible with dielectric thin-film filters. They meet MIL specifications for environmental testing and mechanical durability and are RoHS-compliant.
