Notes of ordering

Please note the following information when ordering:

On request, the testing telescopes can also be equipped with eyepieces of focal length 25 mm or 10 mm. Unless otherwise specified, the testing telescopes include an eyepiece with a focal length of 14.7 mm.
The eyepiece reticle is already included in the scope of delivery of the testing telescopes. Please specify the desired reticle when ordering!
Unless otherwise specified, the adjustment is made to infinite distance of the reticle image at a wavelength of 525 nm. Adjustment to other distances or wavelengths is possible with the tube extension.
When ordering, please specify the desired unit of measurement (mm, arcsec or mrad) for the display of the digital double micrometer!
When making an inquiry or placing an order, you can specify the article number and/or the article description of the desired product. The article description for testing telescopes with straight viewing, variable focus adjustment and mechanical or digital double micrometer is shown on the right.
