The Brunel SP78P binocular is a full specification polarising microscope including Bertrand lens, quartz wedge and wavelength retardation plates. This microscope is very competitively priced and manufactured exclusively for Brunel Microscopes. The binocular head incorporates a lyot depolarising filter to ensure true colour rendition when analysing with plain polarised light.

The Brunel SP78P Binocular specification features a rotating binocular head with x10 widefield eyepieces one of which has a graduated crosshair, a push/pull bertrand lens beneath the binocular head, and a push/pull analysing filter that can be rotated through 90° to cross the polarisers. There is a graduated scale. It also has a filter slot to accommodate the quartz wedge, quarter wavelength and full wave length retardation plates that are all provided as standard with this microscope, a rotating graduated circular stage, with clamping mechanism and lateral adjustment which allows each objective to be positioned centrally in the optical path, and a quadruple objective turret, with an excellent and very positive indexing mechanism, housing x4, x10, x40 and x63 strain free polarising objectives, an abbe condenser, with rack and pinion focusing, filter carrier and iris diaphragm.

The polarising filter is housed above the field lens with a swing out mechanism so that it can be removed easily from the optical path.

One of the most important features of any polarising microscope is the illumination system. Crossed polarising filters obviously  produces a black background, and the brilliance of  the appearance of birefringent objects is dictated by the lighting system of the microscope.  The Brunel SP78P binocular has rheostat controlled quartz halogen illumination, with 6 volt 20 watt lamps located in an easy to reach lamp housing that can easily be accessed from the base of the microscope.

The build quality of this microscope is excellent for the price. It has a modern design with stylish wrist resting inserts on the base. The low position coaxial coarse and fine focus controls are well placed for ease of comfort, and have an inbuilt safety stop and tension adjustment. The fine focus is graduated to facilitate simple depth measurement.
