Standard glass scale is just like a kind of very precise ruler, and on its surface, accurate divisions are equally marked. You may measure the length by counting its divisions. The scale is frequently used, and even built in precise instruments, machining tools as length measuring standard scale. Also it is often used for scale calibration, as well as traceability of measurement standard.
Shibuya optical products are offered with extremely high accuracy varied and different measuring length, pitch and line width, and at a reasonable price. Besides, Shibuya has its own specially designed unique ones.
Shibuya Standard Glass Scale's standard temperature of measuring length should be fixed at 23 ˚C, that is most common environment in workshops of Japanese manufacturer. For further detailed information, please contact with us first.

* In case of that Inspection Report and Traceability Certificate is requested, your item will be measured at one direction 10 random points (23 ˚C) by Shibuya, and then the inspection report and traceability certificate will be issued (chargeable). As for X Y axes or further request, please contact with us for details.
* The measurement (10 random points, 20 ˚C) by JQA (Japan Quality Assurance Organization) or by JSPMI (Japan Society for the Promotion of Machine Industry) is also available. Please contact with us for details.
