- Working distance: distance between the front end of the mechanics and the object.
- The design working f-number (wf/N) is specified. The working f-number could be changed using the variable iris.
- Measured from the front end of the mechanics to the camera flange.
The image of the external walls of the object, captured through the catadioptric system, is inscribed into the short side of the camera detector within a circular crown. On the other hand, the top of the object is directly imaged onto the central part of the detector area: both the lateral and top view of the object are in perfect focus at the same time.
Field of view
The tables show possible combinations of object diameters and heights along with the appropriate working distance and recommended F-number; the “c” parameter for each configuration is also listed.
The “c” parameter describes the dimension of the top view image: it is calculated as the ratio between the central top view diameter and the short side of the detector. The typical ratio between the object height and its diameter is 2/3 which means that, for a given object diameter (i.e. 15 mm), the recommended inspection height will be around 67% of the diameter (10 mm). However, this parameter can be modified to accommodate for different aspect ratios (up to 100%) by adjusting the lens working distance, focus and F-number.

PCCDLFAT: how it works
PCCDLFAT is an accessory designed to increase the central field of view of PCCD optics.
By replacing the pre-assembled protective window with the PCCDLFAT attachment, PCCD optics can inspect the TOP and SIDES of objects with even larger diameters (beyond 25 mm).
Schematics showing the FOVs of PCCD Optics with and without PCCDLFAT. PCCDLFAT extends the central field of view of PCCD optics to image objects with even larger diameters (beyond 25 mm)
