LMT RT 500
Measurement of reflectance and transmittance
LMT® RT 500 is a system for measurement of material reflection and transmission properties.
The equipment can be configured for different measurement tasks.
Measured observables
- Reflectance ρ
- Diffuse Reflectance ρd
- Transmittance τ
- Diffuse Transmittance τd
- Reflectance of flat and convex surface rear-view mirrors
- Transmittance τdif at diffuse light incidence (option)
Supported standards
- DIN 5036 part 3
- CIE Publ. No. 130
- ECE Regulations R 46, R 81
- ISO 5740 – 1982
Hardware
- 500 mm diameter integrating sphere with probe holders
- 30 mm diameter of light sensitive surface, fine V(λ)-approximation
- Stabilised Standard Illuminant A source for measurement of ρ and ρd
- Stabilised Standard Illuminant A source for measurement of τ and τd
