Transmittance integrating sphere UPB-150-ART

for reflectance measurement

Photometry to determine material properties Material properties is a general term used to refer to the reflection, transmission and absorption properties of a material. Photometry hereby refers to a measurement process through which these properties are determined using a photometer. Integrating sphere photometer The integrating sphere is very common in both broadband and narrow-band photometric applications for diffuse sample illumination and determination of the reflected and transmitted light proportions. UPB-150-ART precision integrating sphere With the 150mm diameter, the UPB-150-ART provides a good compromise in terms of precision of the sphere function and level of the measurement signal. Its manufacture from an aluminum block ensures a very precise alignment of the measurement ports to each other. Another characteristic property are the thin circumferential knife-edges of the measurement ports that enable a high acceptance angle for diffuse light.
