black
cable to
ground
blue
cable (LED anode) to your power supply
or external strobe controller
Make sure not to exceed
LEDs maximum rates to avoid
electrical shorts.
2.1.2 Direct LED control usage option
Both continuous and pulsed mode are allowed; the built-in electronics can be bypassed in
order to drive the LED directly for use in continuous or pulsed mode. When bypassed, built-
in electronics behaves as an open circuit allowing direct control of the LED source. Please
note that in such case light intensity adjustment is not possible though the built-in multi-turn
trimmer.
Connection
Connect the black and blue cables as shown below (remove the LED anode protective cover):
2.2 LED source axial position
LED axial position is an important operational parameter that must be correctly set to
obtain optimal illumination homogeneity. LED axial position is adjusted at factory by placing/
removing internal or external spacers of various thicknesses.
Each LTCLHPxxx illuminator is configured by default with the number and type of spacers
needed to achieve the best illumination homogeneity with its corresponding TC
23
xxx
telecentric lens model.
The number and type of spacers needed to achieve the optimal light homogeneity can be
different when LTCLHPxxx is used in combination with TC
13
xxx, TC
12
xxx or telecentric
lenses designed for other sensor sizes.
