Identifying Issues in Lens Design

Our client had sourced a lens that satisfied its written specification, but it did not result in satisfactory imaging, and they were unable to identify what was the source of the problem or describe to their supplier how the lens needed to be improved.

Optikos reviewed the system requirements and the details of the optical and mechanical designs, and subsequently measured the veiling glare and ghost imaging to determine that the lens design had a significant ghosting problem that was exacerbated by reflections off the image sensor. By modeling the design on the computer and relating that to the observed ghosting phenomenon, Optikos was able to determine which optical surfaces required improved coatings. The customer was able to specify to its suppliers exactly what needed to be changed to mitigate the objectionable ghosting and stray light.
