Flat Crystal
Plane optical flats are used to inspect the flatness and planarity of gauge blocks, as well as the flatness of the measuring surfaces and working surfaces of instruments and tools.
Description
The flat optical flat is used to inspect the wrring quality and flatness of gauge blocks, as well as the flatness of measuring surfaces and working surfaces of instruments and tools.
It can also be used to inspect high-precision flat components, such as flat optical elements, high-grade platforms, plates, guide rails, sealing parts, etc.
The flat optical flat is particularly suitable for metrology institutions and laboratories as a standard reference plane and template.
Precautions:
If the desired style is not available in the standard product list, you may contact sales for customization.
