Spectroradiometers are instruments that scan different regions of the light spectrum, providing simultaneous representations of amplitude versus wavelength of the spectrum.
Get highly accurate measurements using the CS-2000A spectroradiometer. The device has the capacity to measure luminances with ranges that reach down to 0.0005 cd/m2. It can also contrast measurements at ranges that reach 1,000,000:1*4. You can use the CS-2000A with a variety of displays and light sources.
