We have a small quantity of these extremely well built Vickers microscopes. All original and therefore also collectors pieces. Large stable illumination base with 6v 15watt lighting. Stage with slide clips and usual substage condenser with iris. Coaxial coarse and fine focus controls. Objectives x5, x10 and x40 with x10 eyepiece. Very good value for a vintage British made microscope.

The SP13 Dual Light microscope is exclusive to Brunel Microscopes and is an ideal microscope for the young enquiring mind without having many of the constraints of a standard biological microscope. The laws of light physics dictates that it is not possible to manipulate or dissect whole objects with a biological microscope because of the closeness of the objectives to the specimen, the fact that images are inverted and that usually whole objects are not transparent so that the transmitted light does not get through. However, by having a light shining down onto the microscope stage from just behind the objectives the SP13 can look at the surface of whole objects when using the two lowest magnifications (x40 and x100). The x400 magnification has the objective just too close to the specimen for the top light to get in.
In summary:
Using the top light whole objects can be examined at x40 and x100.
Using the bottom light microscope slides can be examined at x40, x100 and x400.
This unit has a screen rather that an eyetube and eyepiece. Images are shown directly on the screen which also has a SD card slot so that the images can be saved. In addition, there is an amplification button on the screen to make things even bigger. This si a great piece of kit

Imported from the USA, this is a good quality fibre optic light source with a continuous ring light. The ring light can attach to a stereomicroscope head up to 60mm in diameter via three clamping screws. Fan cooling with brightness control. Condition very good and supplied complete with a voltage adjustment unit (110 to 240v adjustment).
