The Revelation XSP-200X Microscope is ideally suited to both young and old observers, looking to begin macro exploration. The Revelation XSP-200X Microscope boasts a solid, all metal construction with a range of features that encourage, not punish the inexperienced. The locked-on eyepiece prevents accidental loss or damage of this essential element. The smooth rack-and-pinion focus system possesses a slip clutch and focus stop mechanism to prevent over focussing and damage to the objective lens and glass slides. Subject illumination is accomplished by the use of a tilting mirror, located beneath the slide stage.
