Optional Accessories - Detachable Mechanical Stage, Sub-stage Halogen Illuminator, Micrometer Eyepiece, Spare Bulbs, Additional Compensators, Wooden Storing Cabinet, etc.

ADVANCED POLARIZING MICROSCOPE Polarizing microscopes are principal piece of equipment used by the geologists to observe the optical properties of minerals. In has indispensable applications for petrography, crystallography.geology or finding stress points in metal,glass and textiles, etc. It permits orthoscopically to examine and identifify the structures of material with highly resolved distinctive images under various magnifications. Stage - Compact ball-bearing centerable rotating stage, 140mm. diameter, graduated with vernier, lock & stage specimen clips Focusing - By vertical movement of stage, coarse adjustment by rackpinion knobs & fine movement by screw-lever mechanism driven by screw-lever mechanism driven by graduated knobs. Illuminator - Koehler's illuminator with pre-centred 20W tungsten halogen source and integral electric transformer with intensity control is concealed inside the base. Input voltage 220 or 110 Volts Intermediate Tube - Built-in focussable Bertrand lens with center adjustable. Built-in analyzer removable from optical path. Analyzer can be rotated 90° with a vernier reading to 6'. Compensator λ and λ/4 can be inserted in the tube as per requirement Compensator - λ-Gypsum Plate (1st order red compensating plate, 560 nanometers) and λ/4-Mica Plate (145 nanometers).. Objectives - Semi-plan Flat Achromatic DIN Objectives P-4x/ 0.10, P-10x/ 0.25 and P-40x / 0.65 SL. Eyepieces - Widefield Eyepieces WF-10x (Paired) and WF 10x with Cross Polarizer - Fully rotatable swing-out Polarizer and abbe-condenser N.A.1.25 with iris-diaphragm Optional Accessories - Objectives P-20x and P-60x, Micrometer Eyepiece WF10x Micro-photographic Equipment, Wooden Storing Cabinet,Detachable Mechanical Stage, etc
