Ultra-Low light photometer.
PR-810L model is based on Photomultiplier Tube (PMT) and filters.

Using the largest of the 4 fully automated apertures, the PR-810L can measure 1E-6 (0.000001) footlamberts. A fully automated Neutral Density (ND) filter turret provides 3 decades of filtration (10X, 100X and 1000X attenuation) resulting in a 900,000,000:1 dynamic range in any aperture - wide enough for any contrast measurement task. The total instrument dynamic range is 518 Billion:1.
