Light transmission
Light transmission is the visually sensed light permeability of materials. It is particularly important when it comes to specification of window panes on all types of vehicles, display sheets and disks as well as all the other samples whose transmission is assessed with the photometric responsivity (V(λ)) of the human eye.
Regular light transmission
This describes the proportion of light that penetrates through the sample without scattering or dispersion. In addition to the haze value, the proportion of the directed light transmission is also of great importance in wind shields and windows specification.
Measurement of regular light transmission with LCRT-2005-S
Measurement of direct light transmission requires a measurement distance between the light source and device receiver that corresponds to a multiple of the illumination field diameter. The sample is aligned in front of the receiver. This setup correspond to the 0/0 measurement geometry thanks to the quasi-parallel illumination and narrow measurement angle of the receiver.
PMS-RIT stand
The PMS-RIT stand is a useful accessory for the LCRT-2005-S for regular light transmission measurements. The stable base is also suitable for large samples.
LCRT-2005-S spectrophotometer
The LCRT-2005-S can also be used as a spectrophotometer due to its spectral measurement detectors in source and receiver. The spectral range is between 425 and 705nm.
