UV-Vis Spectrophotometer with integrating sphere

This spectrophotometer is used for absorption and transmission spectroscopy but the integrating sphere allows diffuse and specular reflectance and diffuse transmittance measurements to be performed. This allows absoulte absorbtion to be calculated as losses due to scattering can be accounted for.

Instrumentation

Perkin Elmer Lambda 650, UV/Vis spectrophotometer with 150mm integrating sphere

Software

UV Winlab

Operation

Operated in total reflectance, diffuse reflectance, total transmittance and diffuse transmittance.
Wavelength range: 200 – 830 nm
Resolution: ≤ 0.17 nm
Wavelength accuracy: +/- 0.15 nm
