- Luminance Meter
-
The measurement time is greatly shortened. SR-3 can be measured even with a dark sample of 1 cd/m2 or less in about 30 seconds.
-
The new optics system canceled the polarized light error in all wavelength region. (5% or less)
-
Slight light can be measured in high accuracy.(Measuring field 2°, Standard light source A, Accuracy is guaranteed up to 0.5 cd/m2.)
-
The measuring field can be changed by four kinds. (2°/ 1° / 0.2° / 0.1°) All samples can be measured. (Example : Cold Cathode Fluorescent Lamps to Large screen )
-
Application software (CS-900) for Windows is the standard attached.
-
The blinking light such as CRT can be accurately measured, too. Because, SR-3 can do the synchronizing measurement.
-
Four adjustable measuring fields (0.1° ,0.2° ,1 ° ,2°) are selectable for all types of samples.
-
Designed for maximum sensitivity in measuring spot to average luminance.
-
The luminance, chromaticity, color temperature, CIELAB, CIELUV, and color difference are measured, and displayed at once.
-
Because the standard interface is built in, measurements can be performed automatically making it very suitable for inline use. (Please specify GP-IB/RS-232C during purchase)
-
Analog output enables continuous measurement.
-
BM-5A offers high sensitivity by utilizing a Photo-multiplier sensor.
-
BM-7 is a general standard type, and the BM-7FAST enables high-speed measurement.
-
This is a multi function luminance meter, pocket-sized and low cost, measuring angle have three selections, 0.2°, 1°and 2°
-
Wide range measurement with high accuracy, 0.01 to 199,900cd/m(2°type) .
-
Using RS-232C output and the measuring mode select function, it can easily be used for an in-line application.
-
When using the optional extension cable, the detector and display unit can be placed apart.
-
The keyboard unit (optional) expands the range of application. (Deviation, percentage, integral luminance)
