Healing Through Optics

Using 3D digitization, hyperspectral imaging, fibre-optic probes, various laser types and optical sensors, optical engineering can help develop medical devices that generate a wealth of data in a way that is non-intrusive to the human body.

These devices are used to understand the compo-sition and structure of matter and, with the help of artificial intelligence, provide diagnostic and intervention tools with a high degree of accuracy.

After the André-Laurendeau CEGEP received an Applied Research and Development (ARD) grant in 2014, Optech collaborated with Optina Diagnostics to develop a retinal camera based on hyperspectral imaging. The camera is used to obtain spectral and anatomical information from the back of the eye for early and non-invasive detection of diseases that affect vision, including age-related macular degeneration (ARMD), diabetic retinopathy (DR) and glaucoma.

“The project was a true collaboration where two teams worked in tandem to find the appropriate solution. Access to the Optech team’s expertise, equipment and laboratories was a considerable advantage for accelerating our development.”
– Jean-Philippe Sylvestre, Vice-President R&D, Optina Diagnostics

During this project, Optech helped improve the retinal camera by using digital models to validate the solutions proposed by Optina and then test them. Afterward, Optech designed and prototyped a new and improved optomechanical system for getting more accurate images of the back of the eye.

Partner: Dental Wings
Field: Biomedical

Optech’s specialized optical microsystems laboratory has enabled Dental Wings to carry out several optical micro-assembly projects.

Dental Wings develops digital technology solutions for use in laboratories and dental clinics. In 2013, after receiving an Applied Research Tools and Instruments (ARTI) grant, Optech acquired specialized equipment for microassembling optical components that allowed Dental Wings to complete projects involving cutting-edge expertise.

Partner: Dental Wings
Field: Biomedical
Using these acquisitions, Optech set up a specialized optical microsystems laboratory. The lab is used to reproduce industrial manufacturing conditions with a focus on automated micromanufacturing methods, microassembly and quality control.
“The specialized laboratory set up by Optech for microassembling optical components allowed Dental Wings to complete several projects requiring cutting-edge expertise, and its equipment portfolio allowed us to design and implement processes for assembling high-performance optical microsystems. Without local access to these skills and equipment, we would definitely have had to subcontract a larger part of our development outside Canada.”
– Jean-Marc Perot, CTO, Dental Wings
Over the last few years, Optech has carried out many optics microassembly projects in a number of fields requiring high-precision optical components. In the biomedical field, integrating micro-optical devices into an assembly requires very strict assembly tolerances and the development of reliable, trackable processes that are scalable for industrial production.
