Optical system

The optical system is based on the standard RMS 160mm ‘tube’ length and can accommodate an interchangeable range of standard RMS eyepieces. The compact hand-held form has an inverted design with the optical path folded three dimensionally using one Z axis mirror and two XY axis mirrors. The objective lenses, have been specifically miniaturised for the microscope in order to reduce size and weight.

The aluminium optical chassis assembly is decoupled from the external moulded casing, providing a high level of protection from physical shock.

The optical system is illuminated by a white-light balanced miniature light emitting diode. The tube mounting collimates the light source providing a narrow beam. Illumination/contrast levels can be adjusted by moving the light arm angle. The PCB design provides variable brightness control with power options from internal batteries or the external mini USB connection.
