Measurement of Material Coefficients, Reflectance and Transmittance: ρ/τ-Photometer

- sphere photometer for the measurement of reflectance and transmittance acc. to DIN 5036-3, CIE publication no. 38
- determination of the following characteristics:

- reflectance ρ
- diffuse reflectance ρd
- reflectance ρ(ε) as a function of the angle of incidence ε
- transmittance τ
- diffuse transmittance τd
- transmittance τ(ε) as a function of the angle of incidence ε
- transmittance τdiff with hemispherical light incidence
- reflectance ρ of plane and convex rear mirros acc. to ECE R46 and ISO 5740
- haze measurements on optical components
