Richter S-2 Focal Plane ^ Microscope
When used with
Precision Lens Standards this unit can verify and calibrate focus scales on lens mounts to
high accuracy. (Lens standard is optional)
A chrome thin-film
reticle is at the focus of the microscope. An aerial image from the lens being tested is
focussed in the same plane as the reticle.
The R-2 collimator
can be used as an artificial infinity in conjunction with the S-2 Focal Plane Microscope,
which can be checked to factory accuracy by the user. |
