Special imaging optics

In some applications it is necessary to create a specified measuring diameter in a specified distance.
This can be realized with customer specific optics. Please send both data and you will get an offer for this specification:

Part number:ACC 009/d_D (measuring diameter d (mm) in the measuring distance D (mm))

Example: ACC 009/20_2050: d = 20 mm and D = 2050 mm
