The SP22 microscopes have many features that are normally found on microscopes of a much greater price. The optical parts are made from achromatic corrected glass and are standard Royal Microscopical Society (RMS) size. The monocular head rotates trough 360° and has a widefield x10 good quality  eyepiece.

The quadruple position rotating turret is equipped with x4, x10 ,x40 and x100 achromatic RMS objectives, which when used with the x10 eyepiece gives a magnification range of x40 to x1000 which is ideal for all standard biological microscopy applications. The x40 and x100 objectives have a spring loaded front lens element that retracts the lens into the objective on contact with the slide. In addition the stage has a safety stop with a similar purpose.


The slide platform is a full mechanical stage with drop down coaxial controls that makes fine movement of the stage in the required direction very easy. The double vernier scale also allows position identification on the slide.


The focus system is also coaxial with the coarse and fine focus being ideally placed in a low position towards the back of the microscope body. The focus control moves the stage up and down to achieve focus. Beneath the stage is a fully focusable substage condenser with iris diaphragm that is used to focus the illuminating light in the plane of the specimen, with the iris helping to provide clarity of specimen detail. It may sound complicated, but it is very simple to use in practice and fully illustrated instructions are included.


The SP22 base has inbuilt LED illumination with rheostat control that allows the intensity of the lighting to be adjusted to suit the magnification in use.

The microscope is also available with an inbuilt digital camera (SP22D). The SP22D has the same optical performance and mechanical build as the SP22 but incorporated into the microscope is a 1.3M pixel (1280 x1024) CMOS chip digital camera. The camera system is enclosed within the head and shares the image with the eyepiece. The camera element is attached to a laptop or PC via an USB lead. When the slide is in focus with the standard eyepiece it will also be in focus on the computer. Supplied with the microscope is the USB lead and software that is suitable for Windows 7, 8 and 10 (not suitable for Apple operating system). Step by step instructions are provided that require relatively little computer knowledge to get things working.

The software has a large number of applications

• Video clips and still images

• Time lapse video clips

• Full image colour and exposure control

• Automatic white balance

• Saved image orientation

• Distance, area and angle measurement on still images

• Annotation on still images

• Manual and auto exposure options

An aluminium carrying case is available for the SP22 only.
