Opto Engineering® Collimated Light (CL) LED illuminators have been specifically designed for back-illuminating objects imaged by telecentric lenses. This type of illumination is strongly recommended for high accuracy measurement of round or cylindrical parts where diffusive back lighters would offer poor performances.
Key advantages
- COMPLETE LIGHT COUPLING: all the light emitted by a LTCL source is collected by a telecentric lens and transferred to the camera detector, ensuring very high signal-to-noise ratios.
- BORDER EFFECTS REMOVAL: diffused back-illuminators often make objects seem smaller than real because of light reflections on the object sides, while collimated rays are typically much less reflected.
- FIELD DEPTH AND TELECENTRICITY IMPROVEMENT: collimated illumination geometry increases a telecentric lens natural field depth and telecentricity far beyond its nominal specs.
The illuminator light colour can be defined according to the following options:
/R = red
/G = green
/B = blue
/W = white
/IR890 = infrared, peak at 890 nm
/IR940 = infrared, peak at 940 nm
