Santec MEMS swept source for optical coherence tomography and high-speed imaging


The HSL-mini microelectromechanical systems (MEMS) scanner-based swept source from Santec (Komaki, Japan) scans at rates up to 50 kHz while maintaining a wide scan range over 160 nm for high-speed imaging or motion-sensitive optical coherence tomography (OCT), such as ophthalmology and endoscopy. An external cavity design with a diffraction grating maintains low relative intensity noise (RIN).



SANTEC unveils MEMS scanner based swept source, HSL-mini for high speed OCT

December 15, 2010

DECEMBER 15, 2010 - SANTEC corporation, a leading manufacturer of high speed swept laser sources for OCT, has introduced a new MEMS scanner based swept source that overcomes the speed limit of the polygon scanner based HSL series. The new source scans at faster rates, up to 50 kHz, while maintaining a wide scan range of over 160nm.  These combined features provide significant technological advantages in ultra high-speed imaging or motion-sensitive applications, such as ophthalmology, endoscopy, etc.  The MEMS scanner based system utilizes an external cavity design with a diffraction grating and ensures high specification performance as a swept source, maintaining low RIN, and high repeatability, and boasting industrial-class high reliability.  Additionally, Santec supports the integration of the HSL into the customer’s systems, providing numerous options, and OCT system software.


Santec Corporation was established in 1979. It is headquartered in Komaki, Japan and has subsidiaries in America (Santec U.S.A. Corporation), U.K. (Santec Europe Ltd.) and China (Santec (Shanghai) Co., Ltd.). It is listed on the Nippon New Market - “Hercules” section of the Osaka Securities Exchange. Santec serves customers in more than 30 countries; these include most of the world's major telecommunications companies and telecommunication system manufacturers.

Santec's products include a broad range of optical components and tunable laser light sources for the optical fiber industry, together with a range of fiber optic test and measurement instruments. It is particularly strong in the DWDM, CWDM and PON markets and hasrecently developed products for medical imaging and fiber sensor applications.
