#VICKERS INSTRUMENTS M41 PHOTOPLAN LAMP PLUS#
Fortunately, this plus can be adapted, with appropriate adaptor, to US power. The microscope comes with a British power plug, expected considering its origin. At widest point, is approximately 6-1/2 inches. Its working distance at 2.5x is approximately 2-3/4 inches. This stereomicroscope is approximately 12.5 inches tall in working position. The position of the dual mirrors are can changed via the adjustment controls on both the right and left side of the transmitted light base. Dual illumination on stereomicroscopes was first introduced by Professor Riddel back in 1853, and continues to be used. more mirror is shown in the third photograph. The microscope comes with dual substage mirrors to illuminate each of the optical paths in the Greenough design. With its three objectives attached, is substantial, and weighs approximately 12 pounds 7.4 ounces. The Greenough microscope is named after its American inventor Horatio Saltonstall Greenough. As are all Greenough stereomicroscopes, with dual porro prisms. With objective markings of 2.5x, 3.5x, and 10x(on the longest objective) Multiplying the eyepiece magnifications by the objective designations yields: 17.5x, 24.5, and 70x. Triple Turret Stereo Microscope with Incident and transmitted light Base This tan Vickers Instruments stereomicroscope with black transmitted light base comes with two matched 7x eyepieces. Highlands& Islands& NI bidders please request a delivery quotation before payment(This will be at cost) Otherwise the item will be carefully packaged for Courier delivery. The light source is controlled by a separate. Too numerous to mention can be seen in the photos. Most other adjustments are by coarse& fine thumbwheels. The slide table has vernier adjustments in both planes. The eyepieces are Complan 10x magnification. Vickers 10x magnification/0.25, Cooke Baker 40x magnification/0.17& Vickers 100x magnification/1.3. The microscope has 4 object lenses on the carousel. I originally obtained it as a beekeeper for pollen identification. It has been well used but all the elements are tight and work with precision. This Vickers Instruments laboratory/scientific/diagnostic microscope is circa 1970's.
