Calculating the Flange Back Distance |
uEye Camera Manual Version 3.80
Calculating the Flange Back Distance
To correctly determine the flange back distance of a uEye camera, you need to consider the distance between the lens flange and the active area of the sensor and, additionally, the type and thickness of any materials inserted into the optical path.
The distance in air between the threaded flange and the active area is 17.526 mm with C-mount lenses and 12.526 mm with CS-mount lenses.
This mechanical distance can change due to the material-specific refractive index of the inserted materials. The glass cover of the sensor and all filters inserted into the optical path (see Filter Types table) must be taken into account in the calculation.
