Photometer / Tristimulus Colormeter SSL LC-800.x

SSL LC-800.x Photometer is laboratory grade photometer with 1-4 channels ('x' denotes the nr of channels). 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 photocurrent meter

1. Wider dynamic range of 9 decades 

2. 4-channels for separation of X channel to Xred and Xblue (LC-800.4 version)

3. Larger bandwidth at smaller photocurrents 

4. Improved sampling rate 

5. On-the-fly measurement compatible

Measurement quantities:

• Illuminance Ev (lx),
  
• Optical flicker frequency (Hz), Flicker index, Percent flicker (%), Duty cycle (%), EV,MEAN, EV-max, EV-min, Flicker risk (IEEE 1789)
  
• New flicker parameters SVM (IEC TR 63158) and Pst LM (IEC TR 61547-1)
