TCCXQ series
Coaxial telecentric assemblies for sensors up to 2/3”
Key advantages
- Completely free from stray light
Compatible with both reflective and diffusive surface objects imaging - High resolution
For sharp-edge imaging and small imperfections detection - Bi-telecentric design
Same degree of measurement accuracy as standard bi-telecentric lenses - Optimal light collimation
For precise direct light measurement applications - Detailed test report with measured optical parameters
TCCXQ optical assemblies integrate the high optical performances of TC telecentric lenses and the LTCLHP series ability to provide accurate and reliable illumination.
Pairing these two Opto Engineering® flagship products results in a system completely free from stray light and back reflections, while marking superior optical performances (in terms of resolution, telecentricity and distortion) even at the highest magnifications.
This optical layout also minimizes the overall height of the system, while the placement of the camera port allows for easy phase and back-focal adjustments.
TCCXQ assemblies can be successfully employed in high-accuracy measurement applications as well as Automated Optical Inspection (AOI) setups.
Notes
- Working distance: distance between the beam splitter's front mechanics and the object. Set this distance within ± 3% of the nominal value for maximum resolution and minimum distortion.
- Working f-number (wf/N): the real f-number of a lens in operating conditions.
- Maximum angle between chief rays and optical axis on the object side. Typical (average production) values and maximum (guaranteed) values are listed.
- Percent deviation of the real image compared to an ideal, undistorted image. Typical (average production) values and maximum (guaranteed) values are listed.
- At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
- Object side, calculated with the Rayleigh criterion with λ= 520 nm
- At max forward current. Tolerance is ± 0.06V on forward voltage measurements.
- Used in continuous (not pulsed) mode.
- At pulse width <= 10 ms, duty cycle <= 10% condition. Built-in electronics board must be bypassed (see tech info).
- Measured from the beam splitter's front mechanics to the camera flange.
Instructions for use
Operation options
LTSCHP LED modules can be operated in two ways:
- standard usage option: through the built-in electronics
- direct LED control usage option
STANDARD usage option (LED control throuh built-in electronics)
Only conitinuous mode (constant voltage) is allowed.
Connection:
Connect the black and the 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.

- Tolerance ± 10%
- Used in continuous (not pulsed) mode.
- At max forward current.
- Tolerance is ±0.06V on forward voltage measurements.
- At pulse width <= 10 ms, duty cycle <= 10% condition. Built-in electronics board must be bypassed (see tech info).
- Shipped not assembled. See LTCLHP instruction manual.
- Some part numbers are not available in all color options (-R, -G, -B and -W). See page of each product series for available colors.
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, builtin 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).
