5-2 Orthoscopic Observation
}In principle, polarized light enters the light path, parallel to the optical axis, to enable observation of the optical
characteristics of the specimen. Therefore, swing out the top lens of the condenser. Use 4X to 100X objectives.
1. When using the intermediate attachment conoscopic and orthoscopic observation U-CPA, pull out the Bertrand
lens knob to remove the Bertrand lens from the light path.
2. Insert the analyzer and perform observation.
· When the top lens is swung out, the aperture iris diaphragm and field iris diaphragm will not function nor-
mally.
· If the aperture iris diaphragm is stopped down, the field of view may be restricted.
3. Insert a test plate (sensitive tint plate (U-TP530), quarter wave plate (U-TP137)) into the test plate slot. When fully
inserted, the plate is engaged. To remove the test plate from the light path, pull out to first click-stop position.
For details on other compensators, see the separate instruction manuals.
