摘要

IMAGING SYSTEM FOR INVESTOR Microscopes Prefocus BASED ON INVESTOR Porro SECOND DEGREE WITH MODIFICATIONS, comprising: TWO MAIN roof prisms (1-2) placed with their faces hypotenuse (7-8) PARALLEL AND FACING; PREMIUMS TWO STRAIGHT SIDE (3-4) NOT FACED; SPHERICAL CRYSTALS DOS (5-6), wherein the roof prisms SIDE (3-4) ADOSADOS BY ONE OF THE SIDES TO RESTRICT THE RIGHT ANGLE TO FACE HIPOTENUSA (7-8) ONE OF THE MAIN PRISM (1-2) WITH THE pERPENDICULAR TO ARISTA said main PRISMA, REMAINING FREE FACE HIPOTENUSA (9-10) upside to 45. UNDER THESE SIDES SITUATED hypotenuse VAN SPHERICAL CRYSTALS (5-6). ONE OF THE MAIN SURFACES HAS PRISMS (20) perpendicular to the ARISTA POLISHED, to demarcate a crystal plane.
