Flange Back Distance
10.1.1.3.1 Calculation of the flange back distance
To correctly determine the flange back distance of a DCx 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 must be taken
into account in the calculation.
