Optical lapping achieves flatness to 1 µm (±1 µm) at YISHUN; polishing extends it to 0.1 µm. Learn what affects achievable flatness and how to specify it in your RFQ.
Surface roughness controls how light transmits, reflects, and scatters in optics. Learn Ra vs RMS, roughness targets by material, and how precision optical polishing achieves them.
Ultra precision machining achieves tight tolerances and fine surface finishes by controlling not one variable, but an entire chain of potential errors. Machine motion accuracy, spindle behavior, cutti
Diamond turning, grinding, and polishing are not three interchangeable ways to achieve the same result. They perform different jobs in precision optical manufacturing. Diamond turning is often the str
Single point diamond turning, commonly abbreviated as SPDT, is an ultra-precision machining process that uses a carefully controlled single-crystal diamond cutting tool to generate highly accurate sur
Optical polishing improves surface performance primarily by reducing microscopic roughness, processing marks, and localized defects that scatter light away from its intended path. For transmissive com
Discover how mirror polishing processing and five-axis mirror machining enable smartwatch case manufacturers to achieve Ra≤0.005μm surface finishes. Yishun Optical delivers precision mold polishing for wearable components.
Yishun Optical delivers ultra-precision mirror machining and component mold core customization for microfluidic chip molds in IVD and POCT devices, Ra≤0.005μm.
A good optical polishing RFQ should tell the supplier exactly what the component is, what condition it is in before polishing, what the finished surface must achieve, how many parts are required, and
