For the measurement of spectral irradiance, we offer high-quality entrance optics with near perfect angular response and high throughput.
Laboratory as well as evironmentally protected optics in different sizes are available for nearly any field of application.

Our different range of telescopes is used for making radiance and radiant intensity (or luminance and luminous intensity) measurements from displays, reflecting surfaces and sky objects.
For outdoor applications we offer a special rugged, weatherproof range of telescopes.

We offer an extensive range of lightguides, for indoor and outdoor use.

We also offer a range of motorised and manually positioned goniometer stages for variable angle reflection/transmission measurements as well as detector characterisation and LED/luminaire polar plots.
