Servicing and Repairs
The Servicing and repair of microscopes is the main focus of our business.
At JB Microscopes we offer a full and comprehensive service for most makes and types of microscopes, including, Stereo, Compound, Fluorescence, Inverted, Student, and Teaching.
The maintenance of Microscopes is very important to ensure good working order high accuracy and to prolong their lifespan. Working and environmental conditions can slowly degrade the optical and mechanical performance of a microscope to the extent that the end user will find it increasingly difficult to produce consistent results. Regular service routines can help pinpoint potential problems before they become too serious. This makes it more cost effective than waiting until there is a specific problem when major repair work may be needed. We recommend that your microscopes are serviced at least once a year or more frequently if the instrument receives particularly heavy use.
We are also happy to help you with any microscope related problems you may be having. Servicing can be just one microscope or 50 it is not a problem. We provide a friendly, conscientious and value for money service.
Servicing and repairs cover the optical, mechanical and electrical components of the microscope and a typical service will include the following schedule.
Viewing Head
Remove head assembly, inspect, check alignment, clean and re-assemble.
Remove eyepieces, inspect, clean and re-assemble.
Objective Turret
Remove all objectives, inspect for lens contamination, clean and re-assemble to turret.
Check turret rotation and alignment.
Stage
Where appropriate, remove stage and stage clip assembly. Check N – S and E – W mechanisms. Re-grease if necessary and re-assemble. Check stage clip tension.
Clean stage platform and re-locate on main body.
Condenser
Remove condenser. Check and clean lenses and filters. Check Iris diaphragm. Clean and re-assemble. Check condenser alignment controls are working correctly.
Field Diaphram
Check field iris lens and diaphragm for correct operation. Clean.
Light Source
Check that light source controls are working correctly and adjust alignment if necessary. Check for correct bulb fitting. Check transformer unit, if applicable, for correct operation.
Main Chassis
Check that all fitments on main chassis are secured. Clean and lubricate parts where necessary.
Check that fine/course controls are working correctly. Check that tension and stage locking controls are working correctly.
Final Settings
After completion of the above the following is carried out.
Where appropriate set microscope for Koehler illumination.
Check objectives against test slide for optimum numerical aperture.
Check and set eyepieces for par focal and graticule alignment where appropriate.
Check illumination and filter controls where appropriate.
Attachments
In addition to the above, microscopes with the following attachments will have extra work carried out as specified.
Phase Contrast
Set and check all phase contrast objectives/condenser using phase telescope and test slide.
Polariser
Check polariser and analyser lenses for location and alignment.
Fluorescence
Check mercury bulb for hour’s usage and alignment. Set for optimum light penetration. Check fluorescent filter cartridge and other lenses in light train. The above work will be carried out to comply with our quality standards. Additional work necessary as a result of damage, malfunction or repairs will be charged for over and above the contracted/quoted service price. The scope of service may change as a result of different types of microscopes i.e. metallurgical, operating, or stereo. However the above is intended as a general specification that covers most commonly used microscopes.
