This is a low cost option for the Picometer. It uses the Light Optical Table instead of the Precision Optical Table.

The Light Table does not have the heavy rigidity which is required for imaging applications, and has a smaller "free volume" for the sample, but uses the same modular optical components as the other ellipsometers. It can carry the He/Ne laser and photomultiplier detector used in the Standard Picometer, or it can carry a 650nm diode laser and a silicon diode detector (which has less flexibility in following a wide range of contrasts in the surface reflectivity).
