The Zen browser from Carl Zeiss Microscopy, Thornwood, NY, is server-based image databasing software that aids in storage, filing and organization, and backup of large digital data sets such as virtual slide databases. The password-protected software can be accessed via any web browser and includes a user management function to customize access and control administrative privileges. Images are filed together with relevant metadata and customizable supporting documents. Designed to make data and virtual microscopy images accessible to a wider audience, the browser offers a project-based, web-centric database that allows integrated web viewing to enable easier online project publishing. In addition to the web interface, a free Zen browser app for the iPad lets users access their server software and build up a virtual slides database remotely.
