Keuffel & Esser Optics and Metrology Mount, 71-5082
This item is a Keuffel & Esser optical and metrology cradle mount. It has the standard 3.5 inch by 8 TPI thread in the base for attaching to standard tripods, dollies, and trivets. The upper side of the carrier has a dovetail four inches wide but 10 inches in length. There is a cylinder head cap screw on one end of the dovetail, and it looks like there is a position for a second such stop screw, however it is not present. The mount is in very good condition. The part number on the cradle is 71-5082. It does not seem to be a current production item � BrunsonKC does not list it in their catalog. The green texture paint would indicate the cradle was made during the 1960�s, possibly early 1970�s.

Microscope with 10x Crossline 32mm
This microscope is very modular. The central component is the drawtube with focusing mechanism. The body of the instrument is fitted with a long 1 inch diameter threaded flange which is supplied with a locking ring. The thread allows the microscope to be attached to various Gaertner instruments, such as the precisions cross slides, instrument bases with cross-support arms, among others. The rack and pinions focusing has a range of 38mm. The nominal optical tube length of the microscope is 160mm.
Eyepieces are supplied with matched eyepiece adapter tubes so the optical tube length is maintained when switching eyepieces. The tube adapters are usually fitted with spider cross lines and therefore no attempt should be made to clean them! These microscopes are all fitted with the standard M250-242 adapter tube with 90 degree spider lines. The ocular is a type M242 Ramsden 10x, also standard.
Gaertner objectives are continuously threaded over their entire length (RMS standard thread) and have a locking ring. The continuous thread allows precise adjustment of the magnification ratio of the instrument when using micrometer eyepieces or filar eyepieces. Focal length of the objectives supplied with these instruments is 32mm (Gaertner part number M220).
As outfitted, the instrument has the following characteristics:
� 40x total magnification.
� 38mm working distance
� 2.75mm diameter object field
An optional component, the image erecting eyepiece adapter, may be installed instead of the eyepiece adapter tube. Depending on the adapter chosen, the eyepiece angle can be either 60 degrees or 90 degrees from the microscope axis, and an erect image is obtained due to the use of a special roof prism. Due to the extended optical tube length of the prism, the above characteristics would be slightly altered. We have these adapters listed elsewhere.
These microscopes are in good condition. They are in excellent mechanical and optical condition. Cosmetically, they show some evidence of use and may have minor alterations that do not affect typical function of the instrument (such as the addition of a tapped hole in the body tube).

Unknown Massive Steel Linear Stage, 2-inch
This is a really massive linear translation table with a 2-inch range of motion. The platform runs on cross-roller bearings. The table is constructed of steel and has provisions for mounting a micrometer drum and stop unit on either side. In the current configuration, the spindle is fixed to the base, the stop to the moving table. The stop block has three selectable positions . The stop segment is independently adjustable. The micrometer spindle holder may be installed in four separate positions. On the opposite side it appears the spindle may be mounted on the upper table with the stop block facing the opposite direction (see fourth photo).
The base is heavily reinforced with cast webbing (see fifth photo). Both the entire top surface and the four corner positioning feet are precision ground to a mirror finish. The included micrometer spindle is a Mitutoyo 0-1 inch, reading to 0.0001 inches.
Stage dimensions:
Base width � 8 inches
Base length � 10 inches
Table dimensions � 8 inches square
Table height � 2.750 inches
Weight of table � 30.5 pounds
The stage is in superb condition, although there is no manufacturer�s mark anywhere. There is a certification sticker on the side of the table marked Reichert-McBain. McBain has manufactured numerous inspection type instruments for metrology although I am not aware of them having manufactured actual stage components such as this.
