Medical devices and diagnostics
Optical design and analysis for medical devices and diagnostics. Client names are withheld.
Published studies cover a smartphone dermatoscope, laser delivery into a diagnostic cartridge, and an imaging lens for a 4K otoscope.
Typical problems
- A smartphone clip-on imager has to stay sharp when the phone is not seated precisely, without a change to the barrel, retention, or case.
- A diagnostic cartridge has to put more of a laser diode's light onto a small sensing well at more than one cartridge position.
- An otoscope lens has to serve a 4K sensor inside a standard ear speculum, including a catalog-lens path to a prototype.
Published case studies
- Placement-tolerant optics for a smartphone dermatoscope
Redesigned a three-lens smartphone clip-on imager so it stays sharp when the phone is not seated perfectly.
~100x worst-case contrast under sub-millimeter phone misalignment
- Laser light delivery for a diagnostic test cartridge
Co-designed a cartridge lens and lightguide that put far more laser light onto a small detection zone.
25% to 90% optical efficiency into the detection area
- Imaging lens for a 4K otoscope
Designed an otoscope imaging lens for a 4K sensor and fit a prototype version to catalog lenses.
