TYPE FGV MD & MDD STRAIGHT VIEWING TELESCOPE & MICROMETER
Notes on ordering:
When considering placing an order please note the following:
The testing telescope with adjustable focus setting and straight view 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.
When ordering a telescope with digital double micrometer, please specify the unit of display of the digital gauges (arcsec, milliradians).
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 straight viewing and mechanical (MD) or digital double micrometer (MDD) is shown in the right hand .
TYPE FGV MD STRAIGHT VIEWING ADJUSTABLE FOCUS TELESCOPE
Small Size Aperture with
Mechanical Double Micrometer
CA = Clear Aperture FL = Focal Length TE = Tube Extension FOV = Field of View
SD (scale division) = corresponding angle value in arcsec of one scale division of the micrometer screw
TYPE FGV MD STRAIGHT VIEWING ADJUSTABLE FOCUS TELESCOPE
Medium Size Aperture with
Mechanical Double Micrometer
CA = Clear Aperture FL = Focal Length TE = Tube Extension FOV = Field of View
SD (scale division) = corresponding angle value in arcsec of one scale division of the micrometer screw
TYPE FGV MD STRAIGHT VIEWING ADJUSTABLE FOCUS TELESCOPE
Large Size Aperture with
Mechanical Double Micrometer
CA = Clear Aperture FL = Focal Length TE = Tube Extension FOV = Field of View
