Neutral Density Filter, Screw On, 0.05-2% Transmission, LBP2 Profilers

For a replacement, please check ND3 Stackable Filter, Green.

The LBP2-ND3 is a screw-on neutral density filter for the LBP2 system cameras, providing transmission between 0.05% and 2% 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 green housing so as not to cause interference effects.  The damage threshold is 50 W/cm², however, distortion due to thermal lensing can happen at as low as 5 W/cm². This filter is not included with the LBP2 Series Laser Beam Profilers, so it must be purchased separately.
