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.
SYSTEM COMPOSITION
PROFESSIONAL VIDEO-CAMERA with 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.
