4 Classified by material:
(1) Soda glass
The optical glass line ruler has the characteristics of high accuracy, high hardness, low thermal expansion coefficient, and good corrosion resistance.

(2) Quartz glass
Quartz glass is a valuable material. Quartz glass is resistant to high temperatures, has a very small coefficient of thermal expansion, good chemical thermal stability, and comparable to general optical glass in terms of bubbles, stripes, uniformity, and birefringence. Therefore, it is an optical material with high stability for optical systems operating in various harsh environments.
(3) K9 glass
K9 glass has excellent mechanical properties and very low levels of bubbles and impurities, with good scratch resistance. Due to its stable chemical properties, there is no need for special treatment such as grinding and polishing. Applied in many fields such as optoelectronics, microwave technology, diffractive optical elements, etc.

Five Scope of application:
1. The standard line ruler is widely used in various levels of measurement units, research institutes, precision machining plants, measurement rooms and workshops, for accuracy testing and calibration of various measuring instruments and devices, as well as calibration in computer software measurement. It is a high-precision benchmark measuring instrument.
2. The glass line ruler can be used to calibrate the indication errors of projectors, tool microscopes, and image measuring instruments.
3.calibrationStandard glass line ruler for biological microscopesSuitable for two-dimensional measurement, use the standard scale of a glass standard ruler to recalibrate or set the scale of the instrument.
4. Re calibrate the accuracy of the workbench or set linear compensation for the grating ruler.
