Singapore JonDavidson Full time $120,000 - $180,000 per year
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.
