Imec presents compact lens-free digital microscope

Compared to conventional optical microscopes, lens-free digital microscopy removes the need for expensive and bulky optical lens components to acquire and visualise microscopy images. In a lens-free digital microscope, images are captured on a CMOS image sensor and digitally reconstructed using software. Imec’s lens-free microscope features a comparable micrometer-scale accuracy as traditional optical microscopes. While being much smaller and less expensive, imec’s microscope captures a larger field-of-view in one shot, enabling shorter sample processing times. The lens-free microscope paves the way to new applications with living cells and tissues.

“This microscope will enable an abundance of applications, where traditional microscopes are just not applicable,” stated Andy Lambrechts, Programme Manager of integrated vision solutions, imec.

“Recently, we demonstrated its ability to be integrated into a bio-incubator in stem-cell research for cell culture monitoring, and for cardio-toxicity testing, where the microscope monitored contractions of cardiac tissue in response to drugs. With impressive results our team has branched out even further and is exploring its ability measure fabrication tolerances and stress in our in-house developed neural probe chips and for defect inspection of thin-film displays.”

“Imec’s lens free imaging solution is now available as a full, ready-to-use demo kit evaluation system including a light source, image sensor, control and read-out electronics and a software interface,” stated Jerome Baron, business development manager of integrated vision systems, imec. “Companies can use it to try out their own applications, supported by our engineers to fine-tune the hardware and software and customise the systems toward their exact application requirements.”

Imec will demonstrate its lens-free microscope at SPIE Photonics West exhibition (booth 4144).
