RTI Light Probe

Measures the brightness on monitors with the same spectral response as the human Eye

The RTI Light Probe is designed to comply with the needs of QA in modern X-ray departments. With a monitor and a lux adapter, the Light Probe measures the brightness on monitors and film viewing boxes and the ambient light in the room. The Light Probe has the same spectral response as the human eye. That makes it reliable for all different types of measurements, independent of the light source. The spectral response complies with the CIE V(λ) curve.
