Our client is a large MNC with their regional R & D Center in Singapore. R&D in Optical or lens Design, Optical Sensor & System, LightTools, Zemax, CodeV beam shaping optics, objective lenses, ToF systems, micro lens arrays, free form optics and diffractive optical elements.
Responsibilities:

Primarily involves the design of VCSEL beam shaping optics and objective lenses for use in ToF systems operating in the near infra-red or visible wavelength range.
Uses of non-sequential ray tracing simulation tools such as LightTools and Zemax to establish design performance, sensitivity to manufacturing variations, and provide yield estimations.
Help coordinate the manufacturing implementation of lens designs for prototyping and mass production in 3rd party manufacturers, and will need to engage in effective and efficient communication with suppliers on a daily basis.
Assist the Technical Sourcing team in the selection of optical-mechanical manufacturing partners, evaluating their technology and determining their process capability for manufacturing and its suitability for lens designs.
Support mechanical engineers in tolerance, finite element and thermal analysis, and optimise the lens designs to accommodate and ease the assembly or module integration.
Collaborate with engineers across multi-disciplinary teams from silicon architecture, sensor design, systems engineering and applications to ensure appropriate system-level approach to ToF module design.
Assist marketing and customers in the definition of new products by driving feasibility studies, and providing estimation of future product performance.
Perform verification of lens designs and drive manufacturing optimisation and yield improvement with 3rd party manufacturers.

Requirements:

Post-Graduate Degree (PhD or MSc) in Optics or Physics with an emphasis in Optical System Design.
Track record of modelling optical designs as part of a complete system, utilising their in-depth understanding of physics, radiometry and photonics.
LightTools or Zemax or CodeV for illumination system lens design, tolerance analysis and yield estimation.
Experienced in first order ray tracing calculations.
Familiar with the design of optics to perform illumination diffusing and flattening operations, including micro lens arrays, free form optics and diffractive optical elements.
Experience of optical design for low-cost high-volume manufacturing using injection moulded polymers or replication techniques.
An understanding of design and fabrication of thin films for band pass interference filters is desirable.
Extensive experience in setting-up and performing optical measurements in dark room environment, defining and following relevant laser safety procedures.
Experience with Matlab or equivalent software would be highly desirable.
