Microscopes range from simple toys to complex instruments. The toys are fun in the field, but completely inadequate for the adult amateur microscopist. Educational microscopes, even at the lower-end, are considerably better than the toys, and at the higher end are fine for amateur microscopy. The advanced educational microscopes usually have many of the same features, and handle the same, as the lab-grade instruments, but at a much lower cost due to relatively inexpensive optics. What are the minimum features needed by the amateur microscopist? Here’s what I recommend:

A microscope is a relatively simple (yet precision) instrument, and is deliberately designed with hands-on controls for manipulating both the sample and the optical path. Learning the names and functions of the various parts and controls is an essential prerequisite to making an informed purchase, then properly using the microscope.

Multi-Axis Tilt Platform provides angular adjustment about two axes – tilting and in-plane rotation.

Holmarc beam expanders provide accurate, unobstructed and achromatic expansion of any collimated input source and are easy to use. The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The main advantage of Galilean design is that its overall length is smaller compared to a similar power Keplerian design.
