The MX3 has the same optical specification as the mx1 and has the same potential
magnification range of x5 to x120 with additional eyepieces and objectives. The objectives
are on a dovetail slider which makes changing the objectives pairs very simple, x1,
x3, x4 and x6 are available. The working distance at x20 is 57mm.
The MX3 has a raised base accommodating both incident and transmitted illumination
systems. The incident lamp is fitted behind the objectives and shines down directly
on the specimen area. The lighting is controlled by a rocker switch that allows either
the incident or transmitted options to be used alternately.
