Glass measuring scales for stereo viewers

Glass measuring scales are the optimum tool for quick and accurate determination of lengths and distances that are greater than can be seen within the field of view of a measuring magnifier. Scale with divisions of 0.1mm on the clear glass plate and is available in three lengths supplied with a 15x reading magnifier (standard Peak 1962 magnifier) inside an elegant transport box.

These precision glass scale rulers are produced in Germany with hard chrome plated graduations. When measuring lengths and distances it is necessary to ensure that the scale is parallel to the object to be measured, to prevent measuring errors.
