This instrument is used to measure reflected or transmitted distribution of light that is emitted from liquid crystal displays, light fixtures, advertising displays, etc., for the purpose of evaluating diffusion of incident light and visual feeling of samples, including the ones with some special surfaces.
By automatically varying an angle of a light receiving unit, measurements of light distribution are made for each angle for the range of ±80º at 1º interval against a sample's normal line.
Transmittance measurements are also possible by 180º incident light from a light emitting unit.
You can enjoy simple operation using an exclusive control software.
Measurement data by text output (cvs file format) can be used by spreadsheet software.
You can measure diffused distribution of reflected or transmitted light from a light diffusing plate and metallic colored surface, etc.
Dimensions
W 340mm x D 520mm x H 310mm
Light source
Halogen lamp, 12V 50W
Luminous flux
Approx. 3mm
Light receiving angle
-80º ~ +80º ,provided that sample's normal line is 0º.
(It is, however, impossible to measure at the light emitting angle of ±10º)
It is possible to specify any arbitrary angle up to 10 angles.
Measuring interval
To be specified from 1º, 2º, 3º, 4º, 5º
Light emitting angle
Reflectance measurement : 0º to 70º at 5º interval (manual setting)
Transmittance measurement : 180º
Light receiving element
Silicon photo diode
Filter
Filter for visual feeling
Sample size
Minimum : 30mm x 30 mm
Maximum : 110mm x 160mm
Interface
Connection via RS-232C
