Product description

146P microscope equipped with infinity corrected optics offers technical performance for observing samples under light polarizda resulting from wide application in petrography, mineralogy and chemistry of materials as well as in histology and pathology for observacón of numerous structures have birefringence qeu (crystal structures, pigments, lipids, amyloid deposits, ect.).
For this purpose, the microscope has a polarizing filter on the stage that transmits light polarized in the direction NS, and a filter analyzer, above the plate, which transmits only light vibrating in EW. When both polarizers are in posibión orthogonal (at 90 ° apart), extinguished the light generated by the polarizer and not see anything, but if the sample birefringence, birefringence structure will be illuminated on a dark background.

HIGH QUALITY OF IMAGE

Infinity corrected optics and a lighting system that allows you to obtain very high quality images free of aberrations and distortions. For this, the team has a lighting system with diaphragms Köhler camo and openness; precondenser graduate and ABBE condenser (NA: 1.25) height adjustable rack and pinion system. The lighting is provided by a 30 W halogen lamp with dimmer.
The objectives, high quality plan achromatic, are also in the own gun centerable avoiding possible deviations of the beam.

POLARIZATION SYSTEM:

The team has a polarizing filter on the capacitor can be rotated at an angle of 360 degrees and is graduated. The filter analyzer, located in the intermediate tube between the gun and the head has a rotation angle of 90 degrees and graduation with Vernier.
The intermediate tube also has a sliding easily Bertrand lens optical path for observation and a recess Conoscopic accessory for compensating plate inservión between the eyepiece and objectives. The unit is supplied conplaca plaster (1 l), mica plate (1 / 4 l) and a wedge of quartz, which are inserted at 45 ° of the preferred vibration directions of the polarizer and analyzer.

ERGONOMICS:

As important as the technical performance is an ergonomic design that ensures a natural position of the head and body to avoid fatigue when prolonged observations. For this purpose, the microscope has a binocular head 146P Siedentopf type inclined 30 º with adjustable interpupillary distance and diopter correction, and equipped with suitable eye pair eyeglass wearers.
The macro and micro coaxial control are in a lowered position to a more comfortable ride. The right knob is provided with a friction control ring and the left locking lever upper limit of approach to prevent accidentally hitting targets samples.
