basic information
【Specifications】 ■Regarding the interval of the scale lines, we can produce scales with intervals of 1mm, 0.5mm, and 0.1mm. ■The scale line intervals for low-expansion glass scales are limited to a constant interval. The line width will be the same for a single glass scale. ■In the production of low-expansion glass scales, the length of the scale lines is made to be easily visible, as they are intended to be used with magnifying tools. ■You can also choose whether or not to include numbers. For the numbers, we can provide representations of 0, 1, 2, 3, 0, 10, 20, 30, and Roman numerals. You can choose between front and back text. Please specify your preferences at the time of production. ■Depending on the effective length of the scale and the interval of the scale lines, there may be a few instances of line disconnection or color fading. This is due to unavoidable circumstances in the production process. We appreciate your understanding. *For more details, please download the PDF or feel free to contact us.
