There are numerous light-hazard classification standards that may pertain to your medical device: ISO 60601-2-57, IEC 62471, ANSI RP-27-20, ISO 15004-2, ANSI Z80.36, ISO 10936-2, ISO 10939, and so on… In this blog post, I’ll examine certain commonalities and points of potential confusion of the “big 4” incoherent-light-source safety standards: IEC 62471 and ANSI RP-27-20 […]
Moulded plastic light guides are an inexpensive means to “pipe” light around inside a medical device. Their design process makes light guides amenable to a variety of shapes and sizes. Applications include delivering light to an indicator, a switch, or a peripheral diagnostic attachment, thus, these optical guides are an attractive technology for solving a […]
Why Colour-rendering Accuracy is Critical for Full-Colour Medical Device Color Management “A picture is worth a thousand words.” That truism is no-less apt when it comes to medical devices, particularly when an accurate record or real-time presentation of tissue appearance is key to appropriate diagnosis and treatment.
In this post, I’d like to share with you a toolkit that I’ve found works quite well with both my creative process and my workflow: the Jupyter notebook, and the Python/Numpy/Scipy stack.
Five powerful perspectives for the Optics Laboratory Implementing medical device optics projects like a novel measurement scheme, or bringing up a breadboard prototype for the first time, is a dynamic and messy endeavour. I’d like to share five key recommendations for approaching such journeys based on my 25 years of designing and implementing laser-based measurements.
Light from biomedical devices interacts with human tissue, which contains a variety of structures and cell sizes and shapes. In many cases, optical scattering plays a strong role in the propagation of optical radiation. One common approach to simulating scattering is the Monte Carlo technique. Popular optics-simulation software incorporates Monte Carlo scattering, allowing you to […]
