M40 Brightfield Metallurgical Microscope
The Fein Optic M40 metallurgical brightfield microscope is available with reflected light only or with reflected and transmitted light. 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 Semi Apochromat metallurgical infinity corrected objectives offer clarity and high resolution for viewing the smallest details in parts. 5W LED illumination is long-lasting. Ergonomically inclined head places user in the best working position, creating less tension and fatigue after prolonged microscope use.
