M20 Brightfield Reflected Light Metallurgical Microscope
The Fein Optic M20 metallurgical brightfield microscope is available with reflected light only. This microscope is perfect for viewing small metal parts or any type of parts that required high magnification and will not allow light to pass through them. The brightfield plan achromat metallurgical infinity corrected objectives offer clarity and high resolution for viewing the smallest details in parts. 12v, 50w halogen reflected light illumination provides bright light. Ergonomically inclined head places user in the best working position, creating less tension and fatigue after prolonged microscope use.
