A: The 5-Step Galileo system uses a rotating drum to switch between five distinct magnification levels. This provides the dentist with **quick, fixed, and repeatable steps** from low magnification (for a wide field) to high magnification (for fine detail), unlike zoom systems which are continuous but less precise.

A: Yes. The MU series often features a **mobile floor stand** with lockable, smooth-rolling casters. Its counterbalanced, articulated arm is designed for easy, single-handed repositioning, making it highly versatile for use in different dental chairs or rooms within a multi-chair clinic or teaching hospital.

A: It uses high-eyepoint, wide-field eyepieces and **parallel light paths (stereoscopic optics)**, which are inherently more ergonomic than working through loupes or the naked eye. The coaxial LED light is flicker-free and adjusted to reduce reflective glare, all contributing to significantly reduced ocular fatigue.

A: The Orange filter blocks the blue light spectrum (400-500 nm). This is crucial because dental composite filling materials are cured (hardened) by blue light. Using the filter **prevents the composite from prematurely setting** while the dentist is manipulating the material under the high magnification of the microscope.
