M3-F custom focus module specifications worksheet

 

Figure 1: M3-F module exploded view

The M3 Design Platform allows us to quickly develop custom micro-mechatronic modules that integrate easily into OEM systems. Simply supply commands via a serial interface to get precision, closed-loop motion.

 

Custom M3-F focus modules accommodate your specifications for board mounting interface, lens travel (macro to infinity), lens thread, motion control interface and more.

 

Cost and delivery will depend on the customization. We can generally provide Proof of Concept prototypes within 8 to 10 weeks after acceptance of the proposal and receipt of your order. Please fill out this form as completely as possible and we will provide a proposal.

 

You might also consider purchasing a standard M3-F developer's kit for rapid evaluation and prototyping.
