TCDP series are double port bi-telecentric lenses supporting two different cameras to measure objects with different magnification factors. 2X and 4X options are available for imaging one half or one fourth of the full FOV: this can be simply accomplished by switching from one camera to the other with your software application.

Since this technique does not require any moving mechanism we can ensure full magnification repeatability, providing exceptional measurement accuracy with no need of post-zoom recalibration. TCDP optics can fit any camera up to 2/3" format, they can be mounted on CMHO clamping mechanics and paired with LTCLHP collimated illuminators as well as LTRN ring illuminators designed for standard TC series.

KEY ADVANTAGES

Double FOV and magnification
Combining accuracy with flexibility
No need of re-calibrating
Since the two magnifications are fixed
No change in image centering
When switching to another FOV

Notes

Working F-number (wF/#): the real F/# of a lens when used as a macro.
Maximum slope of principal rays inside the lens: when converted to milliradians, it gives the maximum measurement error for any millimiter of object displacement
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 5.5 µm.

TCDP Working principle

TCDP lenses provide two different ports for simultaneous imaging with two different cameras:

Port A images the full FOV at magnification m

Port B images one half of the full FOV at 2X magnification (for TCDP2X xxx) or one fourth of the full FOV at 4X magnification (for TCDP4X xxx)

Fine focusing and phase adjustment

Focusing and adjusting the phase of the two cameras is rather simple. First of all, place a reference object at the nominal lens' working distance.

Add or subtract spacers to the C-mount until best focus is achieved, then rotate the camera phase by untightening the C-mount set screws.

Once the right phase is found, tighten the set screws and lock the camera phase. Do the same for the secondary port: find the right number of spacers for achieving the best image resolution...

....and rotate the camera mount to obtain the best angular alignment of the image.
