Bargains

The SP58 is from the same stable as our SP60, with two differences the RMS screw thread objectives are achromatic and it has critical illumination rather than Kohler. In excellent condition this really is a 'bargain'. 160mm tube length corrected objectives x4 (0.10), x10 (0.25), x40 (0.65) and oil immersion x100 (1.25) with wide field x10 eyepieces giving a magnification range of x40 to x1000. Good size mechanical stage with double vernier scales and coaxial drop-down controls. Beneath the stage is a fully focusing Abbe condenser with iris diaphragm and filter carrier. The microscope stand has low position coaxial coarse and fine focus controls with tension adjustment and safety lock. The LED illumination system is controlled with and on/off switch and brightness control.

This a fine example of the microscope that the RMS recommends for all primary schools. Young people need to see images that they recognise from what they see in real life. The DM1 magnifies x20 which does not seem enough but it makes a ladybird the size of a turtle! This will make sense to any young scientist below the age of let's say 10 years. So often well-meaning relatives give a present of a microscope that magnifies up to x1000. This is like looking at the White Cliffs of Dover from 1 inch away. It makes no sense. Let them see what they know but in greater detail. They can see a bee's sting and the stamens of a flower etc. This unit is in perfect condition.

This really is a bargain. Used only by ourselves and fully guaranteed. An example fo our BM1 long arm with vertical rather than angled eyetubes. The choice of angle of the eyetubes depends on several things including the type of specimen being used and the height of the microscopist to make positioning comfortable. This is effectively a new unit with x10 and x20 magnification options and a flexible LED goose neck lighting system
