The Agilent Technologies Cary 5000 UV-Vis-NIR spectrometer offers high quality photometric performance within a 175 – 3300 nm spectral range. The Cary 5000 performs absorbance and transmission measurements of both solid and liquid samples. Additional configurations allow the incorporation of an integrating sphere to facilitate external diffuse reflectance measurements. Also, a Universal Measurement Attachment (UMA) is available to perform angle-dependent reflection and transmission measurements.
