Automated Reflectance and Transmission Measurement System (ARTA)

The ARTA includes a 60 mm integrating sphere detector, a built in polarized driver capable of measuring BRDF/BTDF with a variable slit and variable sample holder, and a GlanTompson polarizer. Sample measurement spot can be as small as 2x2 mm. Angles of incidence: 0-85° for Transmittance and 5-85° for Reflectance. Compatible with the LAMBDA 950/1050/1050+.

Used in academia, glass, optics, and thin film industries, the Automated Reflectance/Transmittance Analyzer (ARTA) is a drop-in accessory for the LAMBDA™ 950, 1050 and 1050+ UV/Vis/NIR spectrometers. It uses a goniometer to rotate a sample with respect to the beam (varying angle of incidence) and independently rotate an integrating-sphere detector with respect to the sample (varying angle of detection). For any incidence angle/detection angle pairing, spectra may be collected for s- and p-polarized light in the wavelength range of 250–2500 nm.
