Choosing a Medical Device Camera Sensor

Medical Device Camera Sensor Resolution and Pixel Size Camera sensors are key components of video microscopes and endoscopes, fluorescence imagers, X-ray detectors, multiplexed detectors (i.e. detectors that measure/quantify more than one thing at a time), spectrometers, and imaging interferometers. With many options available and many specifications to consider, choosing a camera sensor for a medical […]

Overview of Optical Technologies for Point of Care Medical Devices

This blog provides an overview of optical technologies for point of care (POC) medical devices that have been developed or show promise. Point-of-care (POC) testing is diagnostic testing conducted at or near the location where a patient is receiving medical care (away from a clinical laboratory). POC diagnostic devices allow for rapid diagnoses immediately following […]

Spectrometer from home materials

Make a real-time, wavelength-calibrated spectrometer using common household items. Like many others, I’m currently working from home due to the ongoing COVID-19 crisis. Fortunately, a significant portion of my optical engineering work, such as research, modelling and design, can be done without going into the office. On the other hand, I generally avoid going into […]
