Service:

• We disassemble and clean each major element 

• Replace lubricants 

• Clean optics: oculars, objectives, exposed prism surfaces 

• Inspect electrical system

• Reassemble, align optics, stage, slide tracks, calibrate micrometers 

• Review service before leaving premises on request

Calibration

Calibration is used to determine the value of each micrometer segment or division at the different magnifications.

Micrometer divisions are counted, multiplied by scale and divided by corresponding slide segments * scale.  

Actual power is then divided into the standard (0.1mm). 

Millimeters are converted to microns (u).  

Standard Procedure

We align, adjust to standard in all protocol. We do not over torque and will only under torque at requested preference. 

To over torque is to strip threading and add unnecessary stress to mechanics. 

Therefore, we adjust slide holders, optics, objectives to standard--unless parameters are preset to preference of placement

(e.g. objective order/position). 

In certain cases, we may have to align the fine adjust with the coarse adjust (because the coarse adjust is binding too tightly 

or not tracking). 

This involves an adjustable knurl knob that tightens and releases the coarse adjust. 

If the external lock on the stage is set, you will not be able to move the coarse adjust beyond that point. 

We do not touch locks unless focus cannot be achieved at all. 

We are always happy to provide a maintenance log. 

Ordering Parts

We ask you for

• The make/model/serial number of the microscope

 To receive the correct part directly: 

Please order through the manufacturer, Microscope World or Accu-Scope 

An identification number should be on the part. 

The make/model/serial number of the microscope will ensure that the right part is shipped to you. 

We will install the part at no extra charge or a minimal fee. 

We charge a minimal fee to:

• Install rheostats, switches

• Align leaves of condenser aperture diaphragm 

• Replace springs, ball bearings, tracks of slide holder 

• Increase parfocal length with shims 

Please note that major repairs may require a greater time frame than the 30 minutes maintenance entails.
