Photometer SSL L-40

SSL L-40 Photometer is USB photometer for measuring light flicker and illuminance. It is used as light detector in goniophotometer and LightTester measurement systems.

Features

• Transimpedance amplifier (TIA)
• 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)
  
• 4 measuring ranges
  
• Signal bandwidth: 
• Maximum: 15 kHz @ photocurrent > 10 uA 
• SVM requirement: > 2 kHz @ photocurrent > 100 nA
