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.

Polished qartz or glass domes. The used material HPFS (fused silica) for our quartz domes is a high purity synthetic amorphous silicon dioxide and allows a large field of application, from the deep UV up to the far IR. Quartz domes with 36 mm in diameter are available on stock.

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

These optics for coupling bare fibres are special designed to fit to our monochromators and light sources.

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.

This collimator has been designed for use with our monochromators and light sources in situations where a monochromatic and parallel beam of light is required. Applications include transmission measurement through aerosols and detector calibration.

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.
