The SP50POL is a new addition to our range and is an excellent quality microscope that can function both as a biological instrument and also as a simple polarising microscope. The main features are consistent with the Winchester range of instruments and includes coaxial coarse and fine focus, quartz halogen illumination and full substage condenser system.
The monocular eyetube head is fully rotatable, and the four position objective turret is complete with x4, x10, x40 and x60 achromatic objectives, matched with a x10 widefield eyepiece.
The circular stage has slide clips, and is graduated through 360 degrees, and can be clamped into position if required. The analyser filter is placed in situ underneath the monocular head of the microscope. Safety features includes a focus stop arrangement that can be set as required, and in addition the x40 and x60 objectives have spring loaded front lenses.
The substage condenser has an iris diaphragm and rotating graduated polarising filter. An excellent microscope for those that require a compound microscope that is also capable of being used with polarised light. Highly recommended.

SP70 Polarising Microscope
The SP70 represents exceptional value and includes the full range of polarisation elements expected of microscopes at a much higher price. The monocular eyetube is notched for eyepiece fixing and is complete with x10 W/F and x5 eyepieces together with micrometer insert. A stage micrometer is also supplied.
The body tube has slide “in/out” analyser filter and Bertrand lens, with an additional slot for the 1/4 and 1 wavelength retardation plates and quartz wedge.
The rotating stage is graduated and has slide clips. Focus is by separate coarse and fine focus controls. The strain free objectives, x4, x10, x25, x40 and x63 fit individually into the very positive locating mechanism on the microscope barrel. There is full lateral adjustment for centring incorporated into each objective top. The focusing substage condenser has a “flip-top” lens, iris diaphragm and a rotating graduated polariser.
The unit is complete with a 6 volt 20 watt light source (110 volts available), with lateral adjustment on the field lens. A mirror is also supplied for field working.

Polariser/analyser attachments
We can also supply simple polariser/analyser attachments to give any compound microscope basic polarisation ability. These will be listed as accessories for most of the compound biological microscopes within our range. We also have polariser/analyser filter systems for a number of our low power stereomicroscopes.
For those requiring graduated rotation we offer an advanced polariser/analyser accessory that will fit most compound microscopes and provides a graduated rotating stage mount.
