Setting the measurement distance and the pint ring range index

Setting measurement distance
Five types of objective lenses are available for CA-2500 depending on the size of measuring objects. The relation between the size of measuring objects and the measurement distance for each lens is as follows:

CA-2500A, CA-2500S, CA-2500SW, CA-2500ST

Standard lens

CA-2500A, CA-2500W, CA-2500SW, CA-2500WT

Wide lens

CA-2500A, CA-2500T, CA-2500ST, CA-2500WT

Telephoto lens| With low-magnification macro ring (Macro 1)|
---|---|---
Size of measurement object (One-side length of square)| Measurement distance| Size of measurement object (One-side length of square)| Measurement distance|
115 mm approx.| 900 mm approx.| 57 mm approx.| 500 mm|
275 mm approx.| 2000 mm approx.| With high-magnification macro ring (Macro 2)|
420 mm approx.| 3000 mm approx.| Size of measurement object (One-side length of square)| Measurement distance|
| |
27 mm approx.| 300 mm|

Optical lens features varying light intensity and illuminance distribution of the imaging surface if the focus ring is rotated. Therefore, lens calibration has been done lens by lens according to the distance from the lens to the measurement object (distance indicator of focus ring). Each has its calibration coefficient. Correct calibration coefficient can be applied by selecting what kind of lens is used for which focusing distance, in software CA-S25w.
