2024 TELESCOPE

The 2024 is the metric version of the flagship instrument in our line of alignment telescopes. It is designed specifically to make measurements of deviations from a reference line, and secondarily, to provide an extremely straight optical reference line for any number of alignment applications.

Specification

Magnification:

Varies automatically from 4x at zero focus to 46x at infinity

Focusing range: Zero to infinity

Straightness of line of sight:

+ 0.002″ (0 to 50′); + 0.004″ (50′ to 100′); 0.5 arcseconds beyond 100′

Field of view: 37 minutes at infinity, 42 mm at zero focus

Effective aperture: 42 mm

Optics: Fully coated optics used throughout

Reticle:

All-purpose, double glass, dustproof; cross-pattern with single lines

Eyepiece:

Fully erect image; diopter scale. Right-angle eyepiece and complete projection accessories available.

Optical micrometer:

• Built-in horizontal and vertical optical micrometers

• Displacement: ± 1.2 mm, direct reading to 0.02 mm

• Accuracy: ±0.005 mm over full range

• Scale graduations are red and black to indicate direction of displacement

Focusing knob:

Drum graduated to show focusing distance in meters

Telescope barrel:

Made of through hardened stabilized stainless steel

Barrel diameter:

57.14492 mm (+0, -0.0076 mm) or 2.2498″ (+0″, -0.0003″) – meets A.I.A. specifications

Barrel length: 23.3 cm

Overall length: 45.1 cm

Approx. weight: 5.23 kg

Features

It has two built-in optical micrometers which measure at right angles to each other. They allow measurement of lateral shifts perpendicularly from the line of sight, in both the horizontal and vertical directions. The 2024 has a built-in autoreflection target on its objective lens and includes our model 509 autocollimation illumination unit.
