Single Sided Optical Flats is used to check the flatness and suitability of quantitative blocks and the flatness of measuring planes and working plane of instruments and measuring tools. It can also be used to calibrate high precision plane optics, such as plane optical parts, advanced platforms, flat plates, guideways, seals, etc. It is especially suitable for measuring institute and laboratories as standard planes and templates.
Double sided optical flats as the important optical glass components may be used as a reference (test plate) against which the flatness of an unknown surface can be compared or as an optical window. Double side optical flats has high accuracy in flatness and parallelism. Double side optical flats is used for verifying the surface flatness and parallelism of micrometer, lever micrometer, lever-type snap gauge, Micrometer caliper ect. The double sided optical flats are divided into four series, each of which is divided into six groups, each with four pieces.

The advantages of optical flats include their high precision flatness, which enables accurate measurement and calibration in optical systems. Their transparent optical material allows for the passage of light, facilitating the examination of interference patterns and the assessment of surface quality. The parallel surfaces of optical flats ensure consistent performance in various applications, contributing to their reliability. Additionally, optical flats offer versatility in optical testing and metrology, making them indispensable tools for evaluating the flatness of surfaces and the quality of optical components in industries such as manufacturing, astronomy, and research.
