High Refraction Diamond Turning (HRDT) for NIR Applications
Until now, polymers for high index, heat-resistant, NIR optics could only be molded; prototypes required 8–12 weeks minimum, mold costs raised production break-even points.
Using advanced optical plastics like Ultem™, HRDT can reliably achieve a surface as smooth as 60 Angstroms, with even smoother surfaces theoretically possible. HRDT, a patented process from Syntec Optics, enables direct diamond turning lowering costs by 2 to 5X:
- Suits spherical, aspherical, toroidal, cylindrical, cone and plano shapes
- Works for lens surfaces with multiple diffractive structures
- Supports polyetherimide and polyethersulfone thermoplastic resins
