R21POL Polarizing Microscope
The Fein Optic R21POL polarizing microscope is the perfect entry-level polarizing microscope. The petrographic microscope is available with LED transmitted light. An intermediate tube holds the Bertrand lens with rotating switch, pluggable analyzer rotates 180°. Slots for compensators: Gypsum full λ plate, Mica 1/4λ plate and Quartz Wedge. Polarizing microscope stage rotates 360° in 1° increments and can be locked into position. Stage is anti-corrosive, anti-friction and coated in graphite. Stress free Plan Achromat 2x, 4x, 40x, and 60x objectives come standard, along with a 0.5x focusing c-mount.
