Model : Steropes-LED

Description :

Obtaining good measurement results requires good and stable lighting. With this in mind Admesy developed the Steropes LED light source, which is a stable, accurate light source controlled by a built-in colorimeter resulting in a very high stability of the light output.
With the Steropes the user is certain to have a light output at 0,1% accuracy. Combined with our colorimeters or spectrometers the stabilized light of the Steropes offers the best measurement results.
