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
Accessories
- LMT Pocketlux II for monitoring of illuminance level in target area
