The continuous advancement of optical processing technology is truly remarkable, with ion beam polishing technology standing out among numerous polishing methods due to its unique advantages. Ion beam polishing is an atomic-level, stress-free, non-contact polishing process that uses inert gas ions (such as argon ions) to bombard the workpiece surface in a vacuum environment, achieving material removal through physical sputtering. This polishing method offers numerous benefits:
First, the non-contact processing method avoids surface or subsurface damage caused by pre-pressure in traditional polishing processes, ensuring the integrity of the processed surface.
Second, the high-cleanliness vacuum environment effectively prevents the introduction of impurities, enabling the creation of ultra-smooth surfaces, which is crucial for improving the performance of optical components.
Third, ion beam polishing can quickly converge the surface shape, achieving sub-nanometer material removal resolution and meeting the stringent requirements for final surface accuracy.
Furthermore, this technology has wide applicability, suitable for high-precision polishing of most commonly used optical materials without the need to change abrasives or polishing fluids due to material differences.
In summary, ion beam polishing technology, with its high precision, damage-free, and ultra-smooth surface manufacturing advantages, is playing an increasingly important role in the field of optical processing.
