Measurement

This chapter describes the preparations for measurement and the
measuring procedures.

3.1 Preparations for Measurement 

3.1.1Precautions for measurement 

z

Installation site 

When selecting an installation site, take vibration, dust and humidity into due consideration.

Vibration can affect measuring accuracy. Dust and humidity can impair optical parts, such as the

objective and prism, and the XY stage and moving parts.

z

Precaution for operation

If focusing, making measurements, or mounting work pieces, take surrounding conditions into

account. Be careful not to bump the objective, stage glass, etc. 

z

Objective and Eyepiece

The supplied objective and eyepiece were finely adjusted before shipment.

To maintain performance and accuracy, handle them with care and do not disassemble. Do not

allow the surface of the lens to be scratched or to be exposed to machine oil. If the lens is soiled,

clean it as described in “4.1 Dusting and Applying Oil”.

z

Stage glass

Since workpieces are mounted on it, the stage glass is likely to be scratched or even severely

damaged. Dust the workpiece before placing it on the stage glass. Exercise care so as not to

bump the stage glass with the workpiece. Do not slide the workpiece on the stage.
