Diffractive Optics Ltd

In the era of rapid advancement of photonic technology in the new millennium, the demand for precision optical systems and components is growing in unprecedented speed. Diffractive Optics Limited is well positioned and prepared to meet the challenges in this fast growing optical industry.

Established with over 15 years of solid working experience in precision lens design and manufacturing, we are equipped with the latest manufacturing facilities and design capabilities for optical systems from conceptual design through prototyping and mass production.

The core optical engineering capabilities we are actively practicing are
* Diffractive Optical Element (DOE) fabrication
* Aspheric Optics
* Micro-feature Optics

Diffractive optics is an advanced optical technology that achieves some very promising advantages over conventional optics as highlighted below:
* Extreme dispersive power for chromatic aberration correction in high performance imaging lens systems.
* Wavefront reconstruction capabilities enable the fabrication of laser beam pattern generators, 3D holograms and integrated optical systems.

Aspheric optical systems are recognized for their high quality imaging and non-imaging capabilities with fewer optical elements. Most of our designed lens are aspheric or hybrid (aspheric and diffractive combination) that out-perform conventional spherical glass lenses.

Micro-feature optical lenses include optical surfaces of non-continuous relief structures. They may be in the form of fresnel, TIR, microgroove, micro-lens array and diffractives. This new technology opens up a whole range of design freedom for optical systems in telecommunication, surveillance and high-definition display systems.

Diffractive Optics Limited maintain high growth in business through sustained development of proprietary optical manufacturing technologies that allow us to meet or exceed customer expectations in delivering optical systems, subassemblies and components.

They include:
* Injection-compression molding of various polymer optical lenses.
* Metal optics by precision electroforming and Angstrom-level finish polishing.
* Dielectric anti-reflection optical coatings and metallization in protected gold, silver, chromium and aluminum.
* Single point diamond turning.
* Non-contact optical metrology, including phase-shifting interferometry.

We serve a broad spectrum of industries and support the development of optical systems for high-value added products, namely
* Digital imaging lenses
* Microdisplay projection optical engines and head-up display systems
* PIR motion detection lens arrays
* Laser optical modules for precision leveling and CD pickup head
