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.


Light transmission is a relative measurement. It describes the signal difference of the measured luminance in a geometrically defined radiation beam path. The measurements are done both without a test sample (100%) and with a test sample. The light source of the measurement device is characterized by a spectrum that corresponds to the standard illuminant type A, C or D50. The spectral responsivity of the receiver matches that of the human eye.


LCRT-2005H-S measurement device


The LCRT-2005H-S is elaborately designed for light transmission measurement of thin, scratched and clear samples. The d/0° measurement geometry comprises of an integrating sphere light source and a luminance measurement device. The monitor detector of the light source and that of the receiver are both equipped with a diode array spectrometer. The spectral measurement data enables precise simulation of the required standard source spectra and the photometric responsivity spectrum of the receiver. The sample is aligned in front of the light source for measurement. The degree of light transmission can thus be determined through diffuse sample illumination for thin scratched samples as well. A manually selected light trap is implemented for haze measurements. Multiple LEDs are used in order to cover a spectral range of 380 nm to 780 nm.


The integrating sphere light source is well guarded against shock and stains by its synthetic coating, LED lamps and the protective glass on the illumination field. In order to minimize any effects by ambient light, the measurement is performed using pulsed light. The device is also equipped with a camera to aid in alignment of the source and receiver for freehand measurements. The device can be powered using four AA batteries or via USB. A hard-top casing is also supplied for safe storage and transport of the device as well as its spare batteries and accessories.

The spectral responsivity of the receiver must match that of the human eye. These properties allow ECE R43 conform measurements.

Light transmission and spectral transmission


Light transmission is the visually sensed light permeability of materials. NIR transmission is a physical measurand without actinic effect on the measurement values. Light transmission is particularly important when it comes to specification of window panes on all types of vehicles and buildings whose transmission is assessed with the photometric responsivity (V(λ)) of the human eye. In connection with thermal insulation screens, solar cell windows transmission in the NIR spectral range can also be of great importance.
