High Precision Tristimulus Colorimeter SSL LC 800-400x

SSL LC 800-400x tristimulus colorimeter comprises LC 800.4 4-channel photocurrent meter and CH400x measuring head. x denotes two variants of input optics.

It is a good choice for illuminance measuring application in wide dynamic range. Suitable e.g. for goniophotometer, retroreflection or spatial light distribution measurements where low light levels are measured.

Advantages of new version for multichannel tristimulus colorimeter

1. Common input optics

2. Wider dynamic range of 9 decades 

3. 4-channels for separation of X channel to Xred and Xblue (LC-800.4 version)

4. Larger bandwidth at smaller photocurrents 

5. Improved sampling rate 

6. On-the-fly measurement compatible

Measurement quantities:
