NIR Imaging System Could Help Identify Hard-to-Detect Cancers at Earlier Stage
An optical imaging system developed by MIT researchers could enable physicians to identify tiny tumors deep within the body, leading to earlier detection and treatment of cancer. The system uses fluorescent probes that emit light at different NIR wavelengths, depending on the type of doping element that is used.

Quantum Dots Are Tuned to Build IR Camera Cheaply, Efficiently
To build an inexpensive IR camera, scientists at the University of Chicago leveraged the wide spectral tunability of colloidal quantum dots (CQDs), tweaking the CQDs to develop a formula to detect shortwave IR and another formula to detect midwave IR.

Going the Extra Mile with Contrast Optimization: A Practical Comparison of Micro-Imaging System Optimization
Thu, Mar 28, 2019 1:00 PM - 2:00 PM EDT
This webinar, presented by Zemax, will demonstrate the use of contrast optimization in the development of a micro-imaging system, along with a comparison using other optimization methods. It will also look at results using alternate lens design programs. Contrast optimization greatly simplifies the calculation of the modulation transfer function (MTF), giving imaging system designers a better option for targeting imaging quality. Contrast optimization also improves the speed of MTF optimization, resulting in better design solutions.
