Binocular tubes to suit all users

Microscope ergonomics to the fore with these latest height-adjustable binocular and trinocular tubes, which have been designed with pathology in mind

Additions to the range of binocular tubes for the Carl Zeiss range of upright Axio microscopes ensures all users are suited.

The latest height adjustable binocular and trinocular tubes have been designed with pathology in mind.

The major problem in ergonomy is getting the microscope stand to the right height for each user.

New reports indicate that the first considerations for good posture should be seat height, then table height followed by the viewing height of the microscope.

Common practice has often been to correct the viewing height by changing the tilt angle of the binocular, but this simply adjusts the posture at the neck to compensate for the inability to make the microscope height match the person.

The addition of mechanical blocks of fixed height goes some way to overcome this but they are fixed, not variable, and therefore angle adjustment is still made to compensate.

In addition the inclusion of height spacers without correction of the optics is likely to present itself in changes to magnification factors, modification of colour, reduction in colour correction and loss of parfocality.

Comfort - but at what cost in performance? In the development of the Axioskop 40, extensive research was carried out on a global basis to discover what was needed to correct for height in races that were naturally short and those that were tall.

The solution was the continuously height adjustable binocular tube.

With its smooth vertical action of up to 50mm and binocular folding adjustment of up to 40mm, it is well able to cope with all users.

Its viewing angle of 20 degrees is shallow for a relaxed neck position.

In combination with the 'taller than average' Axioskop microscope stands, the new height adjustable binoculars are suitable for users of every size.
