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 TC23xxx

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 TC13xxx, TC12xxx or telecentric

lenses designed for other sensor sizes.
