Neutral Density Filter, Screw On, 5-20% Transmission, LBP2 Profilers

For a replacement, please check ND1 Stackable Filter, Red.

The LBP2-ND1 is a screw-on neutral density filter for the LBP2 system cameras, providing transmission between 5% and 20% depending on the spectral range. It can be stacked and combined with other filters. The filter is placed at a small wedge angle in the red housing so as not to cause interference effects. One filter is included with the LBP2 Series Laser Beam Profilers.  The damage threshold is 50 W/cm², however, distortion due to thermal lensing can happen at as low as 5 W/cm².
