Definition:Ergonomics is the science of equipment design intended to reduce operator fatigue, increase operator comfort and increase productivity
TECHNOLOGY:
In microscopy design, an understanding of ergonomics together with computer aided design, enables microscopes to be manufactured that accommodate the operator (rather than the operator being forced to assume uncomfortable body positions in order to operate the instrument). This involves ensuring that the microscope eyepieces are at the right level and angle for the user, that the operator can use the microscope while sitting in a comfortable stain-free position, that all controls are easily accessible from a comfortable operating position, and that the microscope setup can be easily changed to suit different users. A badly designed microscope can lead to discomfort, lack of concentration, and ultimately a variety of injuries, such as repetitive strain injury, back, neck, wrist pain, and headaches. A poorly designed working environment can lead to loss of productivity and possible grounds for compensation on health and safety grounds.
APPLICATIONS:
Ergonomic design is particularly important for microscope users that spend long periods at the microscope (for example, cytology screening staff, pathology consultants) although no microscope user should be expected to tolerate an uncomfortable system.
MICROSCOPE CONFIGURATION:
A microscope user should be able to sit 'square-on' to the microscope, with hands and arms resting on the table/ bench. The natural curvature of the back should be maintained. The user should not have to lean forward to use the eyepieces. Minimal movement should be required to operate focus and other controls. Eyestrain can be reduced by ensuring that microscope optics are correctly configured and that the illumination source is aligned and performing correctly. The eyepiece interpupillary distance, diopter settings, and parfocality should be checked.
RECOMMENDED SYSTEM:
All Nikon's bio microscopes and industrial microscopes have been designed for maximum operator comfort and ease of use. Features such as ergonomic eyepiece tube, eye-level risers and ergonomically positioned controls are incorporated in all models.
