OCT VARIABLE OPTICAL DELAY LINE
SMALL FORM-FACTOR
PRELIMINARY PRODUCT DATASHEET
The Gooch & Housego Variable Optical Delay Line provides fast and accurate optical path length control in a compact housing.
Based on a customisable chassis that can be adapted to incorporate additional optical components, the unit is designed to be easily incorporated in to any modular optical coherence to mography (OCT) 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.
