A surface is analyzed for brightness. The sensor measures brightness from the surface optically. 2 blue light flashes with the same angle but different direction are used to measure brightness.  The results of this measurements and the calculated figures for refraction color and polarization are sent to a PC.  The letters showing on the screen are the following for the measured values:

BRI = scattered light from the surface     TEM = ambient temperature


Technical Data:
Power: Powered from PC or PDA (3.2...5V @ 30 mA)
Materials: Housing = ABS natural   Seal = Sealon PTFE   Screws = stainless steel 301
Connection: 9 pole D connector (Palm adaptor available)
Work Distance: 5 thou to touching
Resolution: A number between 0 and 999 within 0.1% accuracy

User Instructions



Like any analytical instrument there are many other things you can do with it. For instance: instead of measuring color you can use it to analyze other surface conditions. The output from your measurement shows in the PC and instead of using the calculated data’s from the sensor you can create your own calibration by using the formula above or other manipulations. Typical applications are the use of the measured values and interpret for different properties like how shiny a surface looks.  


To calibrate to any master and go with the values obtained or any standard in your PC by ignoring the

existing calculated values coming from the sensor. You always can use the values from the sensor as 

default.  You can calculate the new values or put the formula in your PC.
