SERVICE FOR HIGH SPECULAR MATERIALS

High Specular Bench


Our high specular bench is well suited for backward and forward light scatter characterization for all types of materials and objects. The system measures BRDF and BTDF, which perfectly represents the way any surface scatters incoming light in 2D space.

Co-developed with the Center for National Scientific Research (CNRS), the high specular bench has been extended into the infrared wavelengths (3.39 and 10.6 µm). We can now provide scatter measurements from the ultraviolet wavelength of 280 nm to the infrared wavelength of 10.6 µm with a dynamic range of 1013.

The high specular bench is 10 meters long, giving it a minimum resolution of 0.02° from the specular direction.

This system is for measurement services only and is not part of our equipment offerings.

COMPACT AND PORTABLE MEASUREMENT SOLUTION

Mini-Diff V2


Mini-Diff V2 is a compact, portable solution for optical scattering characterization. You can measure the BRDF and BTDF of any kind of material and object. Mini-Diff V2 accurately captures measured surface characteristics, including roughness, defects, coatings, and paint.

Mini-Diff V2 is delivered with its own suitcase, which includes calibration standards, software, and cables.

ROBUST 2D/3D SCATTERING MEASUREMENT CAPABILITIES 

Mini-Diff VPro


Mini-Diff VPro is a camera-based 3D hemispherical scattering measurement solution. Like the Mini-Diff V2, the Mini-Diff VPro provides BRDF, BTDF, and TIS measurements. It delivers color, reflectance, and transmittance data.

The Mini-Diff VPro is integrated in a single box, which controls stray light and temperature deviation during measurements, and provides a high level of stability and precision. The instrument offers a choice of incident angle on the sample from 0 ° to 60°, motorized and controlled from the Mini-Diff software.

STAND-ALONE SCATTERING MEASUREMENTS SYSTEM

REFLET 180S


The REFLET 180S optical bench is easy to use for spot inspection or quick analysis. REFLET 180S is especially suited for backward and forward light scatter characterization for all types of materials and objects. It allows you to measure the light distribution contained in the radiation lobe of these materials in photometric and colorimetric terms. Moreover, the system measures BRDF and BTDF, which perfectly represents the way any surface scatters incoming light in 3D space.
