The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
Microinjection is a simple mechanical process usually involving an inverted microscope with a magnification power of around 200x (though sometimes it is performed using a dissecting stereo microscope at 40–50x or a traditional compound upright microscope at similar power to an inverted model).
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

Because of the need for new universities and colleges during the post-war period, there was a demand for microscopes and accessories and Prior developed instruments for this market. The Science Master Microscope, introduced in 1957, was used in schools. The established Prior Monocular Dissecting Microscope was supplied for educational use. [4]
Additionally, Littmann added the stereo telescope system with a common objective magnification changer. [8] In 1965, the Model 100/16 Slit Lamp was produced based on the slit lamp by Littmann. This was soon followed by the Model 125/16 Slit Lamp in 1972. The only difference between the two models was their operating distances of 100 mm to 125 mm.
A traveling microscope. E—eyepiece, O—objective, K—knob for focusing, V—vernier, R—rails, S—screw for fine position adjustment. A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm.
Cover outside water spigots. Before the temperature drops below 32 degrees, outdoor water spigots attached to homes should be opened to allow to drain water out, closed and then covered.
