Lens Milling and Grinding

Our milling and grinding process consistently upholds a superior level of product quality by achieving precise shapes, tight tolerances, and smooth surface finishes in accordance with rigorous standards. The automated procedures effectively minimize defects, thereby enhancing overall product quality. This ensures the production of optical components tailored for applications where precision is of utmost importance in the field of optics.


Lens Grinding and Polishing 

Our lens grinding and polishing process is a multi-step journey towards perfection. It commences with manual abrasive rough grinding, followed by high-speed fine grinding for meticulous shaping and smoothing. We conduct regular thickness checks to maintain defined tolerances. Traditional pitch precision polishing and CAD/CAM-integrated high-speed precision polishing ensure exceptional surface accuracy and reduced irregularities. Every lens is meticulously inspected using our in-house metrology tools, such as interferometers, spectrophotometers, and micrometers, guaranteeing precision, optimal performance, and top-notch quality.

Experience precision redefined with Q-flex 300 MRF™ Polishing Machine. Its dynamic adaptability, rapid size adjustments, and versatile optimization capabilities make it the ultimate choice for achieving unparalleled results in optical polishing. From challenging spheres to intricate freeform optics, elevate your polishing game with Avantier’s cutting-edge innovation.

Precision Optics Polishing with Satisloh SPS-200

Our in-house Satisloh SPS-200 efficiently polishes spheres, aspheres, and freeform surfaces (5-200 mm). This versatile machine handles optical surfaces like cylinders and toroids. With advanced features like Synchrospeed, Variospeed modes, and ADAPT technology, it ensures precision in producing customer aspheres and freeform optics.

Precision Lens Cutting with Sidai SPCM-M1

At Avantier, we kickstart our lens manufacturing journey with the cutting-edge Sidai SPCM-M1. This cutting system allows us to monitor infeed speeds with unparalleled precision, resulting in flawless lens diameters and bevels. The integration of automated cycles, including robot-assisted loading and unloading, guarantees precise lens centering and beveling. Our commitment to automated precision machining and rigorous quality control ensures consistent production of high-quality optical components, optimizing operational efficiency.

Immersive Ultrasonic Cleaning Process

Our lenses go through a thorough immersion and ultrasonic cleaning process. Our expert technicians immerse and rinse the optics repeatedly in solvent until they are pristine. Ultrasonic cleaning ensures efficient and non-destructive removal of contaminants, maintaining optical component cleanliness and performance throughout the manufacturing process.

Optical Coating

Avantier specializes in the process that involves applying thin films to optical components, enhancing light transmission, modifying reflection, or manipulating polarization. These coatings come in various types, including filter, beam splitter, high-reflective, low-reflective, and anti-reflection coatings, each serving distinct purposes. Cutting-edge technologies like IAD E-Beam, IBS, PARMS, and APS are employed in the production of these coatings.
