Product Description

2024BL Alignment Telescope

Bright line & bright field reticles, metric micrometers

Like most of our alignment telescopes, the 2024BL uses the design of the 2022 as its basic building block. However, the 2024BL has metric micrometers as well as 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 2024BL includes a built-in auto-reflection target on the objective lens. An autocollimation illumination unit (our model 509) is included with the instrument.
