Which problems do we solve:

• Sunsensors for terrestrial applications are either not reliable enough or not affordable for volume applications.

• Sunsensors for space are very expensive and generally bulky or not reliable enough for long duration missions.


Lens R&D

Commonality between space and terrestrial markets

• High reliability• Low cost

• Volume production (with small satellites becoming more important)


Applied core technologies

• Unattended machining of the housings

• Wafer scale manufacturing of the membranes

• Housing integrated connector

• Vision based pick and place assembly

• Fabless operation to the largest extend possible.

extended temperature sunsensors Lens R&D

BiSon64B

• BiSon64 sunsensor with additional baffle to restrict albedo sensitivity


Transport box annex flight cover


• Needed to protect baffle during transport

• Cover can be re-used as remove before flight item

Conclusions

• Lens R&D is specialized in high reliability sunsensor with a very good quality to cost ratio.

• Integrated connector and Pick and Place assembly allow for cost effectiveness in volume production.

• Obtaining heritage will largely improve the competitiveness.

• New developments are on the way to secure additional markets and the future.
