Vibration Isolation Granite Surface Optical Table

Granite Surface Optical Table

Material:

Made by high quality granite. Supply with 0, 00, 000 grade.

Mounting holes are available with extra cost

Features:

1.High precision stability resistant to deform and guaranteed accuracy under

normal temperature.

2.Any cutting or scraching for working surface does not bring about rough

edges which might influence its measuring precision.

3.Non magnetization.

Advantages:

1.large mass, stable, strong anticorrosion

2.Using healthy natural granite tables to displace steel tables.

3.Wear resistance long service life

4.No-rust and anticorrosion
