For holding optical reference lines |
 |
|
|
The 2062 alignment telescope's apparent simplicity belies
its extremely precise and useful nature. It is
designed to hold an optical reference line for other
instruments, for use as a boresight telescope, or to
evaluate equipment on its own using the principles of
autocollimation. All standard spherical
adapters and optical squares will fit the 2062. It has an autoreflection target on its objective lens,
and comes complete with an
autocollimation illumination unit (our model
508, operating on 110-220 volts, 60 Hz). This item
may be purchased without the built-in autoreflection target by
specifying model number 2062-NAR.
