Total Absolute Measurement System (TAMS)

Whatever detector you choose, TAMS maintains the highest accuracy with the widest wavelength range for angle-dependent measurement. Commonly used in the analysis of glazing found on architectural and automotive glass as well as photovoltaic cells in the solar industry, TAMS is a useful addition to any production lab tasked with the measurement of transmission and absolute reflectance at variable angles.

• Fully automated goniometer design capable of measuring bi-directional reflectance and transmittance and angular resolved scattering
• The accessory occupies the detector compartment only
• Separate detectors for reference and sample beam, both can be exchanged by the operator for other detector modules that are optimized for different applications
• Angular resolution 0.01° for both sample and detector stages
• Angular accuracy 0.02° degrees for both sample and detector stages
• Angular range sample stage +/- 180°
• Angular range detector stage 15° – 345°
• Angular range in reflectance 7.5° – >80°, depending on sample size
• Angular range in transmittance 5° – >80°, depending on sample size (sample – detector inter-reflections occur for angles < 5° that compromises the accuracy)
• Sample size up to 150 x 150 mm with the standard sample holder (200 mm x 180 mm with other means)
• 200 mm Rotating sample platform with M5 screw holes on a 25mm x 25mm grid

Applications

• Absolute measurement of directional Reflectance and transmittance
• BRDF/ BTDF measurements

Unique flexible detector sets

For each application you can choose the best detector set.

• Sphere Detectorsets for maximum accuracy (to capture all additional beams from for example thick and slightly curved samples
• Standard Detectorsets for maximum sensitivity (BRDF/BTDF an scattering measurements)

Autosampler

The TAMS autosampler (fully automated and integrated in TAMS user interface) is capable of performing measurements on a 6 inch wafer at different positions when installed in a TAMS accessory Multisampling is possible by placing a holder for 19 x 1 inch samples or 5 x 2 inch sample. You can also design your own holder into the autosampler.
