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.
