Background:

Scratches on optical surfaces degrade element performance.
Complete scratch removal is technically challenging and expensive, especially for deep scratches.

Purpose of the Study:

To propose scratch morphology transformation as an alternative to scratch removal.
To develop and demonstrate a method for transforming scratch shapes to mitigate performance drawbacks.

Main Methods:

Measuring scratch morphology.
Establishing scratch transformation models.
Applying transformation techniques using magnetorheological finishing (MRF) and HF etching.

Main Results:

Demonstrated transformation of scratch morphology.
AFM measurements confirmed the effectiveness of the transformation process.
Transformed scratches were found to be acceptable in engineering applications.

Conclusions:

Scratch morphology transformation offers an economical alternative to defect-free fabrication.
This method significantly reduces fabrication time, cost, and risk while preserving optical quality.
