For Cary 100 and 300 UV-Vis spectrophotometers
The DRA-CA-30I measures reflectance and transmittance inside the spectrophotometer s sample compartment. This diffuse reflectance accessory has an inexpensive, high performance, 70-mm diameter integrating sphere that measures samples with diameters up to 150 mm. The DRA CA-30I easily changes between transmittance and reflectance measurements, and measures both diffuse-only and total reflectance. A Spectralon reference plate, its composition giving the highest diffuse reflectance of materials and coatings over the UV-VIS-NIR spectrum, and an 8° wedge is provided for total reflectance measurements. The CA-30I DRA requires an Extended Sample Compartment for measuring reflectance of samples thicker than 25 mm.
