UV Vis NIR spectrophotometer is used to measure and analyse how much light travels through the sample and how much is reflected off of it.
EN 9050, EN 410
A glass sample is positioned in the instrument. A light beam traverses the sample, and goes in an integrating sphere with three detectors (Pmt, InGaAs and Pbs).
Choose an 150mm integrating sphere for rough surface glass measurement (solar glass)
Measurable wavelength range: 220-2500nm
Diameter integrating sphere: 60mm or 150mm
Three detectors: Pmt, InGaAs and Pbs
Sample size : 50x50mm for 60mm diameter integrating sphere
Illmited for 150mm diameter integrating sphere
