## Finding Information on an Axsun OCT Product

Excelitas' market leading Axsun SS-OCT laser engines and imaging products are available across a wide range of specifications, in several physical configurations, and with a variety of optional integrated system components such as K-clocks, high-speed data acquisition (DAQ) boards, balanced photoreceivers, motorized variable delay lines, and OCT interferometers.

*Physical* characteristics (e.g. dimensions, connectors, etc.), *functional* characteristics (e.g. features, workflows, software, etc.), and *performance* characteristics (e.g. spectral range, sweep rate, etc.) are often shared across Axsun product categories, necessitating a multi-dimensional approach to presenting technical information.  The articles in this **Knowledge Base** are typically categorized by functionality or physical configuration; performance-related information is conveyed on [individual laser test reports](https://docs.axsun.com/axsun-knowledge-base/ref-manual/ss-oct-laser-engine/getting-started).
