CDM goniophotometer

Rainbow Light CDM goniophotometer_1A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. Goniophotometers measure the spatial distribution of light visible to the human eye at a specific angular position. With this information we can calculate illuminance, light intensity, distance, light efficacy, and flashing degree.

Edaphic Scientific’s CDM Goniophotometer comes with an optical spectrometer, rotating goniometer, and dedicated software. The dedicated software package has 3D graphics for state of the art representation of lux, CCT, colour, CRI and many other variables.

 

how do the CDM-01 and CDM-02 work?

Rainbow Light CDM goniophotometerThe CDM goniophotometer is very simply to use. Connect the CDM to your Window’s PC or laptop with the provided USB and open the free software. Set the light source into the goniometer. Point the instrument towards the light source and then click start measurement in the software. The user can then scroll through graphics and tables for immediate results. Interpretation of data can be made on the spot or saved for additional analysis later. Data can also be saved as Excel files.

The CDM measures light in the portion of the electromagnetic spectrum between wavebands 380 and 1100nm. Light enters the instrument and a unique spectrochip and CCD turn the photons into electrons for further analysis via the inbuilt computer. The results are displayed instantly on the touch screen in the user-friendly software.

No calibration and no maintenance is required.
