getSpec RAY Flash is an easy and save to handle and compact VIS spectroradiometer. The included easy-to-use software has the full complement of radiometric and colorometric functions requisite for research, diagnostic, and quality control applications. Its miniaturized design makes it suitable for laboratory as well as industrial use.
getSpec RAY Flash measures luminance/ radiance and illuminance/ irradiance as well as photosynthetically active radiation (only cw) of continuously pulsed, single pulsed and cw light sources.
Pulsed sources are measured in illuminance mode using the diffuser cap synchronized with the measured lamp cyclus. Radiometric and photometric values are indicated in exposure per puls.
Furthermore colorimetric values (CCT, chromaticity, color purity, dominant wavelength, CRI) and circadian metrics / photosynthetically active radiation are calculated from the spectral data. Therefore it is suited for the test of pulsed light sources such as flash lights, emergency and traffic lights as well as for the measurement of illuminance in rooms, puplic facilites etc.
Advantages
- USB powered
- optical synchronisation to continuously pulsed sources
- no electrical clock signal necessary
- triggering of single pulses
- easy to install and to operate
- powerful but easy to use software
- DLL and measuring firmware commands
