PTCal150

Safe and effective treatment with phototherapy and photodynamic therapy (PDT) relies on precise dosimetry. In hospitals and in clinical research, the PTCal150 is the benchmark for precise measurement of the spectral irradiance of all phototherapy and PDT light sources. 

Designed with research-grade optical components, the PTCal150 spectroradiometer provides optimally accurate patient exposure data and offers total confidence in phototherapy radiometer calibration. 

Determine heating characteristics and gain insight into the temporal variation of irradiance to guide the application of phototherapy and PDT. 

A compact dual monochromator with precision cosine-corrected input optics provides excellent stray light performance over a very wide dynamic range, enabling accurate measurement of tungsten filament, LED, metal halide, xenon arc, fluorescent and dichroic light sources.
