Endoscopic Lens Alignment Project
ME 424/426 Senior Design
The Sponsor: Stryker Endoscopy,
based in Santa Clara, CA.
Design a fixture that allows adults with average motor skills to align
and epoxy an objective lens, prism, and negative lens through precision
movements. The assembly time should be less than one set of lenses per
hour. The lenses must not be scratched during handling.
Specifications: Assembly time of 40 minutes,
translation repeatability of 0.001 in, rotational repeatability of 0.5
degrees, and a training time of two hours for an individual with experience
Above is a picture of (from left to right) the prism, negative lens,
and objective lens compared to the size of a dime, and a fully assembled
and cured set of lenses next to a pen.
