Multiphysics Software

COMSOL, Burlington, MA, has released the latest version of its Multiphysics software. In addition to Version 5.4, it has released to two new products that provide performance improvements and additional modeling tools. COMSOL Compiler allows users to create standalone COMSOL Multiphysics applications. Compiled applications are bundled with COMSOL Runtime™ — no COMSOL Multiphysics or COMSOL Server™ license is required to run it. Specialists can create simulation applications with the Application Builder that was released a few years ago.

Translucent Compound

Foster, Putnam, CT, has introduced a new translucent compound. The technology with ProPell™ T offers lower lubricity and translucency in medical device components when added to lower durometer TPU and Pebax polyamide elastomer compounds. Similar to the existing ProPell product line, ProPell T offers reduced coefficient of friction (CoF) while maintaining critical mechanical properties and improved manufacturing and handling of medical catheter tubing. In addition, it offers a proprietary surface enhancing additive that also provides translucency.

Fast-Curing Epoxy

A one-part, high-strength epoxy is available from EpoxySet, Woonsocket, RI. EB-350M-7 can be cured as fast as 1 minute @ 180 °C. This high-dielectric formulation can be used with intricate microelectronic components that require electrical insulation. It has a high glass transition temperature of 132 °C and is rated for continuous use from –55° to 220 °C with intermittent use to 300 °C. It also exhibits high thermal conductivity making it an excellent bonding choice for any application requiring heat dissipation. The medium viscosity epoxy is specifically designed to be anhydride free. It is ideal for surface-mount applications that require complete cure in one reflow cycle or rapid production operations where structural support is required.

Image Signal Processor

Omnivision, Santa Clara, CA, has launched a high-definition medical image sensor family. The OH01A employs the PureCel®-S stacked-die architecture to provide the compact size, high resolution, and cost-effectiveness required for the next generation of disposable and reusable endoscopes and catheters. The sensor provides 1280 × 800 resolution at a rate of 60 frames per second in a tiny 2.5 × 1.5 mm package. These features make the sensor a suitable imaging solution for many diagnostic endoscope procedures, including airway-management (esophagoscopes, laryngoscopes, thorascopes, pleuroscopes, bronchoscopes, mediastinoscopes) and urology (utero-renoscope) applications.

Light Engine

Lumencor, Beaverton, OR, offers new light engines that produce powerful outputs based on an array of solid state light sources. The SOLA SE UV-nlR and SOLA SE V-nIR light engines turn on and off in unison producing white light that replicates the spectral output traditionally obtained from mercury lamps. The UV output centers on 365 nm and the violet (V) centers on 395 nm. They each efficiently excite nuclear dyes like DAPI and Hoechst. At the other end of the spectrum, a near infrared source at ~735 nm now excites Cy7 and ICG. The 500–600 nm output of the SOLA light engine, obtained from the application of the company's proprietary light pipe technology, excites fluors in the visible (VIS) spectral region such as mCherry, TRITC, and Texas Red.
