Photometer SSL L-40

SSL Resource - Photometric Testing Efficiency

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 
  • Sampling rate 
  • Maximum: 100 kHz 
  • SVM: 36 kHz (1s measuring time) 
  • P_st^LM : 2 kHz (1-5min) 
  • Photocurrent measurement range: 
  • 0.5 nA - 30 uA (L40) 
  • 5 nA - 300 uA (L40.2) 
  • Linearity <0.1% 
  • USB power supply, RS-232 communication Compatible with SSL photopic measuring heads (LH)
  • Broadband photometer with CIE 1924 photopic sensitivity spectral response
  • Measuring head: LH-33, LH-66, and LH1010 (Spectral match f1'<1.5%, 3%, 6% or 10% to CIE 1924 V(λ) function)
  • Options: temperature sensor, Luminance head (different field of view options in the range of 1.4°-16°), Stray-light tube (different field of view options in the range of 25°-60°)
