NA2 / NAK2
(dependent on staff, technique)
0.3 mm (with parallel-plate micrometer)
FOK73 eyepiece (optional): 40x
|Shortest focusing distance
|Compensator setting accuracy
To improve accuracy a parallel plate micrometer
can be fitted over the telescope objective. The parallel plate
micrometer permits direct readings to 0.1mm and estimated readings
to 0.01mm. This makes the NA2 and NAK2 an ideal precise level for
deformation studies or industrial measuring tasks.
The NAK2 model has an internal glass circle for
reading horizontal angles. Combined with the stadia calculation of
distances from staff readings the NAK2 circle adds the application
benefit of detail survey work.
