Volume Holographic Gratings (VHG's) provide the capability of narrowing and stabilizing the wavelength of semiconductor lasers by forming an external cavity laser (ECL). The standard configuration of these ECL's is to use a collimating lens followed by the VHG to provide feedback to the resonator and lock the wavelength. In this configuration both elements have to be carefully aligned.

This product line integrates the VHG in a fast-axis collimation lens (FAC). Besides the advantage of having a single element, the integrated element is also less sensitive to alignment tolerances.
 
QUALITY - Ondax and Ingeneric combine experience and expertise to bring this unique product line to you.

INGENERIC ensures substantial quality insurance throughout the whole manufacturing process. From the incoming component inspection to the precise final control of each processed item, all steps are recorded. If required a customized test set-up can be realized to ensure that there will be no deviation from the measured characteristics when the optic is subsequently used in industrial practice. All digitally saved inspection and measurement reports can be provided upon request at any time.

ONDAX is a leading manufacturer of Volume Holographic Gratings, consistently delivering the highest quality and performance VHG’s.
