Opto Engineering LTCLHP Series Illuminators
High Performance Telecentric Illuminators
LTCLHP series are high-performance telecentric illuminators specifically designed to back illuminate objects imaged by telecentric lenses.
LTCLHP telecentric illuminators offer higher edge contrast when compared to diffused back light illuminators and therefore higher measurement accuracy. This type of illumination is especially recommended for high accuracy measurement of round or cylindrical parts where diffusive back lighting would offer poor performances because of the diffuse reflections coming from the edges of objects under inspection.

Features
- Complete light coupling
All the light emitted by a LTCLHP 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 their actual size 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. - Excellent illumination stability featuring no light flickering thanks to very high current stability over time even at low currents.
- Precise light intensity tuning thanks to the leadscrew multi-turn trimmer positioned in the back.
- Easy LED source replacement and alignment for all the LED colors offered by Opto Engineering
