UTILIZING THE LENGTH MEASUREMENT FUNCTION OF A MICROSCOPE FOR QUALITY CONTROL

In this article, we shall present the “Points to Consider,” “Usage Guidelines,” and “Recommended Microscopes” when utilizing the length measurement function of microscopes for quality control.

POINTS TO CONSIDER

While some microscopes have the capability to measure length, two operational issues may arise:

(1) The microscope itself is not a traceable measuring instrument.

(2) Calibration, except for some high-end models, must be performed by the user. (Errors may occur due to user operations.)

USAGE GUIDELINES

When used for quality control purposes, there is no issue with internal calibration. However, clarification is needed regarding the standards used in internal calibration. In other words, implementation is feasible if we can meet the following three conditions:

  • Using a microscope with reproducibility capability.
  • The reference device used to check the accuracy of the microscope is transparent.
  • Standards with traceable capabilities are available.

We have customers who have obtained ISO9001 certification and continue to use our products.

RECOMMENDED MICROSCOPES

When utilizing the length measurement function of microscopes for quality control, we recommend the following:

 

Microscope model CT200HD:

 

 

◆ Rare in the mid-range product line. Lens-camera interlocking system

The camera collects data from the lens and automatically utilizes the calibration data stored in the camera’s internal memory:

・ No adjustment required by end-users.

・ Values remain unchanged regardless of end-user operations.

◆ Providing special options with accurate measurement scale

May include calibration certificate and test results table for accurate measurement scale. (Charges)
