HOW AUBOR USES SINGLE POINT DIAMOND TURNING TO ELEVATE OPTICAL LENS PRECISION
At Aubor Optoelectronics, precision is not just a requirement—it's our philosophy. As global demand grows for high-performance infrared sensing lenses, imaging optics, and AR/VR modules, the need for ultra-precise manufacturing capabilities has never been greater.
At Aubor Optoelectronics, precision is not just a requirement—it's our philosophy. As global demand grows for high-performance infrared sensing lenses, imaging optics, and AR/VR modules, the need for ultra-precise manufacturing capabilities has never been greater. One of the key technologies that sets Aubor apart in the optics manufacturing world is our use of Single Point Diamond Turning (SPDT)—a process that allows us to shape optical surfaces with nanometer precision.
What is SPDT and Why Does It Matter?
Single Point Diamond Turning is a form of ultra-precision machining that uses a natural or synthetic diamond cutting tool to produce complex optical surfaces, including aspheric and freeform geometries. Unlike conventional CNC machining or polishing methods, SPDT can achieve surface roughness levels under 10 nm Ra and form accuracy in the sub-micron range, which are critical for optical performance in infrared and visible light applications.
This capability is especially vital in the manufacturing of non-spherical Fresnel lenses, PIR sensing optics, and polymer-based IR lenses, where optical uniformity and surface quality directly impact signal consistency, sensitivity, and false alarm rates.
SPDT at Aubor: Where Optical Design Meets Manufacturing Excellence
At our dedicated optics factory, Aubor has invested in multiple SPDT lathes equipped with high-speed air-bearing spindles and nano-resolution linear scales. These machines are operated by our in-house lens engineers and CAM programmers, who collaborate closely with optical designers to translate simulated lens profiles into mold inserts or directly-turned prototypes.
Our SPDT process is not limited to prototyping. We routinely use diamond turning to:
Fabricate custom mold cores for high-precision injection molding of Fresnel and PIR lenses.
Generate freeform surfaces used in AR/VR waveguides and compact imaging optics.
Polish high-refractive index plastic materials such as COC, COP, and PMMA without inducing thermal damage or surface stress.
By combining SPDT with our in-house coating and molding capabilities, Aubor achieves end-to-end control over optical quality—from nanometer-level tool paths to final lens performance under real-world conditions.
Real-World Application: Enhancing PIR Sensor Performance
In recent PIR lens development projects, our SPDT-finished tools enabled the successful injection molding of Fresnel arrays with highly uniform facet angles. This led to enhanced infrared beam convergence, improved signal-to-noise ratio, and reduced false triggering under thermal turbulence. We also achieved better consistency in detection distance and field-of-view (FOV) alignment compared to lenses made from traditional tooling.
In security monitoring and smart home systems, where PIR sensors are expected to distinguish between human movement and environmental noise, such manufacturing precision is the key to reliability.
