The 2030 is essentially the same as the 2022 alignment
telescope but has a right angle eyepiece and a two-reticle
system consisting of a dark field, bright line reticle as well
as a bright field, dark line reticle. These features
specifically enhance the unit's accuracy and ease of use when
autocollimating. The 2030 includes a
built-in autoreflection target on the objective lens. An autocollimation illumination unit
(our model 508) is
included with the instrument, operating at voltages from
110-220VAC.
