1. Product overview

LTCLHP series are high performance telecentric illuminators featuring excellent illumination

stability, precise light intensity tuning and easy replacement of the LED source, specically

designed to back illuminate objects imaged by telecentric lenses.

LTCLHP telecentric illuminators oer higher edge contrast when compared to diused 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 diusive back lighting would oer poor performances because of
the diuse reections coming from the edges of objects under inspection.

2. Instructions for use

2.1 Operation options

LTCLHP telecentric illuminators integrate LTSCHP modules as light sources.
LTSCHP LED modules can be operated in two ways:

• standard usage option: through the built-in electronics

• direct LED control usage option

2.1.1 STANDARD usage option (LED control through built-in electronics)

Only continuous mode (constant current) is allowed.

Connection

Connect the black and brown cables to your +12 / +24 V power supply.

Light intensity adjustment

The built-in multi-turn trimmer allows to control the light (LED forward current) intensity
with a very high degree of precision: you can bring the current intensity from minimum to
maximum with 21 full turns of the adjustment screw. Simply remove the protective cap and
rotate counter-clockwise the adjustment screw to increase light intensity and vice versa.
