Gaertner 14x Ramsden Ocular Adapter with Glass

$40.00

This is a type M250-240 eyepiece adapter for use in Gaertner measuring microscopes. It is a bit shorter than the normal adapter because it is exclusively used with the shorter focal length M240 14x Ramsden ocular (not included).

Unlike the typical adapter with a 90 degree spider cross line installed, this adapter has the type M204S glass scale. This disk has a 10mm long scale graduated in 0.1mm increments, numbered every 10th line. There is also a cross line indicating the center of the field of view.

The sleeve is in excellent condition, but the glass scale is quite dirty. It also appears that some of the pigment used to fill the engraved lines has been rinsed away – the lines are not uniformly dark. For that reason this is priced as would be an empty adapter tube – a new reticle may be installed at the user’s discretion.
