Projection lens selection
The pattern drawing which has to be projected must be inscribed in a 11 mm diameter circle, same diagonal of a 2/3” detector.
For example, the pattern drawing could cover the entire 11 mm diameter area or be like a 8.8 x 6.6 mm rectangle or, again, be a square whose side is 7.78 mm.
Unless the projection optics introduces significant distortion, the shape of the projected pattern will preserve the features and aspect ratio of the engraved pattern.
The projected area size will be equal to 1/M, where "M" stands for the magnification factor of the lens when used as a standard viewing objective.
LTPRXP series can integrate high resolution C-mount lens for 2/3” detectors (11 mm image diagonal), using the mount adaptor included in the product package.
Here is a list of the projection diameters and the recommended projection distances with different types of optics.
