Bausch & Lomb StereoZoom 4 Pod, 0.7x to 3x, B&W
Good used Condtion

These are very nice examples of the Bausch & Lomb StereoZoom 4 microscope pods that started it all. Black lower portion and white upper portion (sometimes metal; later instruments, of plastic) mean these were of the later production range. The StereoZoom 4 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 ranging 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.

These pods are in very good to excellent cosmetic condition and fine optical/mechanical condition. The dust seals beneath the ocular tubes are present and remain pliable. Alignment is very good.

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.
