Type FGV

Notes on ordering:

In case of order please note the following hints:

The testing telescope is equipped with an eyepiece f=14.7 mm but can be equipped with eyepieces f=25 mm or f=10 mm on request.
One reticle and one eyepiece are included in the delivery. Please specify the reticle when ordering!
If not specified otherwise, the testing telescope is adjusted to infinity at 546 nm wavelength. Adjustment to other distances or wavelengths is also possible on demand.It is possible to specify the testing telescope either with the article no. or/and with the article description.

The nomenclature of the telescopes with adjustable focus setting and with straight viewing is shown in the right hand graphic.
