Other design features |
- Common position of focuses for both magnifications - s'F' = 168 mm
- Diffraction limited aberration correction
- Switching between magnifications through moving internal lens, without the device dismantle
- Other intermediate magnifications are available with condition of focus shift, see above data for f‘ = 178 mm (7")
- Correction of focal shift by slight shift of the movable lens around its base position
- Other combinations of magnifications on request
- Design can be customized
