Screen Imaging Goniophotometer BTC 2000
Super fast goniophotometric measurement of light sources
/ SOLUTIONS / BTC 2000
SSL BTC 2000 combines screen imaging with a goniophotometer for fast wide angle beam pattern measurement of light sources.
Measurements according to various standards like
UN ECE, FMVSS etc.
can be made significantly faster than with a goniophotometer. The typical measurement times are 5 minutes for H+/-50,V+/-15 degrees or 29 minutes for H+/-90, V+/-90. BTC 2000 produces comparable results to turning goniophotometers with an accuracy of +/-4%. The dynamic measurement range is from 0.3 cd up to 70 000 000 cd.
Measurement parameters:
- Luminous intensity in Zone, Group, Line, Single test points
- Cutoff
- Color and stability
- Beam
pattern
- Axial
luminous intensity
- Maximum
luminous intensity
- Beam distance
- Isolux curves on the road
surface and vertical plane
- Isolux curves on the
horizontal level at luminaire height
- Partial luminous flux and efficacy
- ANSI/NEMA FL 1-2009 test routines to measure
- beam distance
- maximum beam intensity
- runtime of photometric performance of flash lights.
Options:
- Input power measurement
- Spatial color parameters
- Far-field photometer add-on
