Verily Retinal Camera

I joined Verily as a full time Product Design Engineer in 2024, working on the next generation, AI enabled retinal camera.

The Verily Retinal Camera is an ophthalmic camera used to take digital photos of the human eye, offering high quality image capture with no dilation needed, illumination optimization, and advanced burst imaging. The device is a Class II medical device.

As part of my role, I led the design and development of several subsystems.

Light shielding system: I worked on a subsystem intended to shield the camera user from seeing the inside of the device as they were being screened, as well as preventing outside light from entering the imaging area. I optimized the mechanical performance and manufacturability of the system, developing it from a prototype concept to production-ready. This involved the design of sheet metal, die cut, and injection molded parts. To evaluate the design, I created test setups for subsystem motion cycling to characterize the full system reliability. The design exceeded all required specifications for light blocking and cycling.

I also owned the kickoff of tooling for a set of 7 injection molded parts. I created detailed part drawings for each part and worked with international suppliers on DFM schedule to meet an engineering build. After the build, in preparation for production, I worked with the suppliers to run parameter DOEs to improve part quality, fit, and function.

Microdisplay subsystem: I developed the mounting assembly and fixture for a microdisplay to provide focus adjustability to micron level accuracy. I designed and prototyped multiple concepts, created contactless measurement setup with laser displacement sensors, and performed detailed tolerance analysis on the design. The final design exceeded focus requirements and was ready for system integration.

Optomechanics: As part of this role, I was exposed to much of the optomechanical design and built my understanding of optics, optical test setups, and optical requirements. I also collaborated with our domestic & international optics suppliers on optomechanical design of the camera lens tube, ensuring optical performance within mechanical integration of the microdisplay, motor, and PCBs inside the camera enclosure.
