Product description
Based on a customizable chassis that can be adapted to incorporate additional optical components, the unit is designed to be easily incorporated into any modular optical coherence tomography (OCT) or similar interferometric system architecture.
Optical interface is through a single or dual fiber pigtails which can be specified to length and terminated with all commonly used optical connectors. Internal optical sensors can be used as reference location and travel limit switches.
Our variable optical delay line provides fast and accurate optical path length change in a compact housing. Based on a point-and-return architecture with a customizable chassis that can be adapted to incorporate additional optical components, the unit is designed to be easily incorporated into any modular optical coherence tomography (OCT) system architecture. The optical interface is through a single fixed fiber pigtail which can be specified to any length and terminated with all commonly-used optical connectors.
This unit is designed to be easily incorporated into any modular optical coherence tomography (OCT) or similar interferometric system architecture.
