LMT VELAS® GO-CL 6580
Precision and accuracy of VELAS® goniophotometer laboratories is on a par with all LMT® goniophotometers, last but not least due to the usage of class L photometry acc. to DIN 5032-6.
Vehicle goniometer for in-situ vehicle lighting assessement
- Goniometer with light source rotation (turn-table) and moving photometer (acc. to CIE 070, IES LM-75)
- Turn-table Ø=6.5m diameter for loads up to 3500 kg
- Horizontal angle -180° ≤ H ≤ 180°, resolution 0.01°
- Vertical angle coverage typically -7° ≤ V ≤ 6° typical (≙ 8m height), resolution 1 mm
- Vehicle dimensions according to UNECE category M1 (length ≤ 7.0 m and width ≤ 2.0 m)
- Test distance 25m
- Tactile measurement system for determination of vehicle position on turn-table
- Electric servo controls with absolute angular encoders (all axes software or manually controlled)
Photometric equipment
- Class L photometer according to DIN 5032-7:2019
- Imaging luminance measurement device (ILMD, type II acc. CIE 244:2021) for rapid capture of luminous intensity distributions
Test & measurement application
