Radiation Pressure Series

The Radiation Pressure Series is Scientech’s newest innovation, designed to accurately measure high power levels from lasers that would normally require expensive, large water-cooled calorimeters. These instruments measure the radiation force exerted by the laser beam on a mirror and significantly improve response time, size, and scalability. The mirrors are designed to reflect ≥99.999% of the laser energy and allow continuous measurement. Radiation Pressure Series instruments actually improve in accuracy as laser power increases.

Power is determined via the following:

P = cF / 2r cos(θ) where

P = optical power θ = angle of incidence F = force c = speed of light r = coefficient derived from mirror reflectivity
