Where to Buy Optical Coherence Tomography Instruments and Components

G&H is an established manufacturer of high quality optical components and optical sub-systems for the biomedical imaging market with manufacturing bases in the UK and the USA.

Our extremely wideband optical coupler offers uniform performance over a 140 nm wavelength range for spectral domain OCT, and can be integrated into modules like our OCT optical delay line. We also offer a compact OCT optical spectrometer with high resolution and image capture rate, completing a line of modular OCT components that may be purchased for research and OEM use, or integrated by our engineering team into a customized, complete system.

Originally developed for ophthalmology, Optical Coherence Tomography (OCT) now spreads over to a variety of applications. The benefit of this technique is the imaging capability of sample structures even at a few millimeters depth with micrometer resolution. For example, invisible defects lying underneath the surface of manufactured parts or different layers in biological tissue and in medieval paintings can be visualized. OCT relies on low coherence interferometry utilizing spectrally broad light sources like superluminescent diodes or femtosecond lasers.

TOPTICA has developed a new optical sampling method: Electronically Controlled Optical Sampling (ECOPS), which speeds up TD-OCT measurements by several orders of magnitude avoiding movable parts in the set-up, using two synchronized femtosecond fiber lasers. The imaging depth remains large and the scan can be hold on any position or zoomed in on interesting features in the OCT image.
