SYSTEM COMPOSITION

LEICA biological Microscope with professional lenses, recommended for the longitudinal and sectional analysis of fibres and yarns.

-High quality and accuracy Microscope

-Phototube trinocular viewing body with Siedentopf design, to adjust the interpupillary distance without changing the focussing.

-Koehler illumination device for the phase contrast and micro photographs (20W).

-Objective image viewing.

-Polarising filter (for a better sample viewing), blue and green coloured filters.

-High precision focussing system.

-Slide movement device with micrometric regulation.

-On screen magnifications: from 128X to 2000X.

-Highly accurate revolving lenses system.

Note: by using the 0.50X additional lens between the microscope and the video-camera (available as optional) the on screen magnification rate decreases by 50% and the field of vision increases by 50%.

-The mentioned dimensions and final magnifications also depend on the hardware in use.

-The above mentioned magnifications and fields of vision have been calculated by using a 17” monitor with 1280X1024 resolution.

PROFESSIONAL VIDEO-CAMERAwith 1/2’’ CCD; compared to the 1/3’’ CCD, it has a much wider field of vision – hence a wider surface of the sample is visualised – and a quicker reaction to light variations. Complete with achromatic C step connector with 1:1 lens, for the insertion on the microscope, to give the maximum contrast, colour and planarity quality.
