Reticles

Reticles are a part of collimatorstesting telecopes and autocollimators. All reticles have a diameter of 12 mm and a thickness of 1 mm.

The clear aperture of a reticle used at the illuminated side of an autocollimator is 6 mm and at the eyepiece side 10 mm. One Exception are autocollimators with reticle turret. Here is also the illuminated side 10 mm.

The clear aperture of reticles used in collimators or telescopes is always 10 mm.

General Selection Criteria

General information:

  • The clear aperture of a reticle used at the illuminated side of an autocollimator is 6 mm and at the eyepiece side 10 mm. One exception are autocollimators with reticle turret. Here is also the illuminated side 10 mm.
     

  • The clear aperture of reticles used in collimators or telescopes is always 10 mm.
     

Please review the following to aid in correct reticle selection for your specific application:

  • Not all reticles can be used as the eyepiece and collimator reticle. Please note therefore the examples of application for the different reticles or contact us.
     

  • If the focal length of the objective lens is greater than 300 mm or, for example, a small mirror diameter leads to a strong stop down, reticles with larger line widths are recommended due to the better contrast ratio.
     

  • If you choose an autocollimator or testing telescope with 90° viewing and reticles with lettering (e.g. coordinate division etc.) please specify the direction of use (A, B, C, D) with your order!

Examples for Reticle Combinations

Note: The reticle combinations are valid for autocollimators as well as for combinations of testing telescopes and collimators.

Determination of Wedge Error of Optical Components:

Collimator reticle: Diaphragms (208 740...208 759)
Eyepiece reticles: Crossline (208 111...208 115)

or

Collimator reticle: Crossline (208 111...208 118)
Eyepiece reticles: mm-scale (208 304)


Fast Angle Measurement:

Collimator reticle: Polar coordinate reticle (208 241, 208 860) or mm-scale (208 401)
Eyepiece reticles: Crossline (208 111...208 115)

Adjustment for Sharpness of Optical Systems and Testing for Resolution:

Collimator reticle: Siemens star (208 201, 208 202) or resolution test (208 211...208 217)


Eyepiece reticles: Crossline (208 111...208 115)

Adjustment of an Autocollimator to a Mirror or of a Collimator to a Telescope:

Collimator reticle: Crossline (208 111...208 118)
Eyepiece reticles: Double crossline (208 123, 208 125, 208 127)

Note: The reticle should be chosen, so that in symmetry adjustment a bright gap appears between the double crossline and the single crossline.


Angle Measurement (Determination of Angle Deviations):

Collimator reticle: Crossline (208 111...208 118)
Eyepiece reticles: Angle graduation (arcmin) (208 411...208 431) or line graduation (208 436...208 443)

For use in autocollimators / collimators with reticle turret:

Collimator reticle: Angle graduation (arcmin) (208 411...208 431)
Eyepiece reticles: Crossline (208 111...208 115)

Angle Graduations For Eyepieces

Example of application:

As eyepiece reticle for the measurement of tilting angles of plane mirrors in arcmin

Note: The angle graduation for autocollimators (AK) is designed to directly indicate the tilt angle of the mirror to be measured. If corresponding reticles are used in testing telescopes (F) to determine the angle of view, the result must be multiplied by 2.

Angle Graduations For Illumination Sleeves

Example of application:

As collimator reticle for the measurement of tilting angles of plane mirrors in arcmin

Note: The angle graduation for autocollimators (AK) is designed to directly indicate the tilt angle of the mirror to be measured. If corresponding reticles are used in collimators (K) to determine the angle of view, the result must be multiplied by 2.
