Bausch & Lomb StereoZoom 4 Pod 0.7x 3x
$90.00
These are nice examples of the Bausch & Lomb StereoZoom 4 microscope pod that started it all. Being of the gray color, this represents the �first generation� of the instrument. It was introduced in the mid-1950s and remained in production for over 50 years with very little change.
This was by far the most popular of the StereoZoom series, with a zoom range of 0.7x to 3x Magnification can be further varied by exchanging the oculars (B&L has eyepiece pairs from 10x to 33x designed for use with the stereo pod), or by threading an auxiliary objective adapter onto the front of the pod. The later are available in various magnifications from 0.3x to 2x, but they alter the working distance of the pod. This yields a magnification range of 2.1x to 180x depending on the combination of oculars and auxiliary lenses selected.
The pods are in excellent cosmetic condition and fine optical/mechanical condition. The dust seals beneath the ocular tubes are no longer present (the earlier seals tended to dry out and crumble away). Alignment is checked and verified. The gray pods are more difficult to clean than the later generation instruments because the dust glass under the ocular tube can only be reached after complete disassembly of the pod (in later units the dust glass was easily removed for cleaning). These glasses tend to collect a film of outgassing from the lubricants used in the zoom mechanism, and in serious cases can render the pod close to useless. Internal surfaces of the dust glasses and the front objectives are cleaned (photo of pod base was taken before cleaning objectives). Zoom mechanism is relubricated to prevent image shift during zooming
Pod catalog number is 31-26-94. With standard 10x oculars (not included) the field diameter ranges from 28mm at 0.7x to 6.6mm at 3x, with a working distance of 100mm. Instrument remains in focus throughout the zoom range.
To make a complete instrument you need a focusing yoke (included with some of the simpler stand versions), a support stand, and a pair of oculars. Optional needs would include an illumination source. Inquire regarding the availability of complete systems or multiple units.
