LB-581
Polarizing Trinocular Microscope
FOR TRANSPARENT OR SEMI-TRANSPARENT SPECIMENS
Specifically designed for use in routine and university level teaching laboratories. The LB-581 polarizing microscope features a highly robust construction and first class optics designed to provide a long life and excellent quality images.
Designed with students in mind the number of removable components is minimized and the operation made as simple as possible. As standard a set of four, very high quality, strain-free, achromatic objectives form the heart of the instrument. A set of inserts allow viewing of all standard mineral types. The optics are also fully corrected so that changes in the viewing angle from the prism in the head during interocular distance adjustments does not cause any color changes.
