10 Tips for Medical Device Optical-Breadboard Prototypes

When designing a medical device made of complex, multi-functional mutually interacting subsystems it’s best to de-risk those subsystems instead of coming up with a paper design, assembling it, and hoping it works first time. De-risking individual subsystem behaviours one at a time enables more-focused assessments and improves troubleshooting. For an optical subsystem, this de-risking is […]

A Comparison of Detection and Imaging Methods Used in Optical Coherence Tomography

Optical coherence tomography (OCT) is an imaging technique with many current and potential applications in medical devices. The most common medical uses of OCT are in ophthalmology and optometry, in which OCT is commonly used to take cross-sectional or 3D scans of the eye’s anterior and posterior segments. Other areas of active development include dentistry, […]

Tolerancing Simulation for Medical Device Optical Systems

Tolerancing is often an essential step in understanding the manufacturing/assembly requirements of an optical system designed for use in medical devices. The use of optical design software for tolerancing simulations is a valuable tool for identifying the specific manufacturing/alignment errors that can be allowed and their limits. Zemax OpticStudio® is a popular optical design software […]

Revolutionizing Medical Imaging Devices with Optical Imaging

Optical imaging tools can enhance the crucial role of biomedical imaging in accurately identifying diseases and monitoring their progression. Conventional medical imaging devices such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and positron emission tomography (PET) are commonly used in clinical settings (Figure 1). However, these imaging modalities are limited in their […]
