LMT Retro 2000

High-accuracy night-time measurement of reflex materials

LMT® Retro 2000 is designed for testing of retro-reflectors used in all kind of applications.
One Photometer head with lens system can be freely positioned at observation angles between

  • 12′ and 120′ (100 ft acc. FMVSS 108 ) or
  • 0.2° and 4° (15m acc. CIE 054)

Sensor design

  • Si-photoelements with fine adaption to V(λ)-curve
  • Optical desgin of the lens system efficiently supresses stray-light
  • Precision photocurrent amplifier for short circuit operation

Projector

  • Planckian radiator with color temperature equivalent to Standard Illuminant A (2856 K)
  • Uniformity according to ECE and DIN requirements ≤ 2 % within 200 mm Ø or
    FMVSS 108 ≤ 5 % within 225 mm Ø
  • Illuminance control circuit via SI-photovoltaic cell feedback
