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 […]

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 […]

Optical Safety for Ophthalmic Instruments

This blog covers the optical safety limits and maximum exposure limits of wavelengths in the IR, UV and visible light spectrum for ophthalmic instruments. Optical safety for ophthalmic instruments focuses on ocular exposure limits because the eyes are the most light-sensitive part of the body and ophthalmic instruments are intended to interface directly with the […]
