SSL BTC 2000 Screen Imaging Goniometer
Description
SSL BTC 2000 combines screen imaging with a goniophotometer for a fast wide angle beam pattern measurement of light sources.
Measurements according to various standards can be made significantly faster than with a goniophotometer. The typical measurement times are 5 minutes for H ±50°,V ±15° 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
SSL BTC 20 is a lighter camera based setup for measuring narrow beam light sources.
