Bright line & bright field reticles, English units
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 509) is included with the instrument.
