Key Features & Uses of OCT Spectrometer

Optical Coherence Tomography (OCT) Spectrometer is a technique used to drive 3D images of the internal layers and structures of a tissue sample unreachable by other techniques or surgery. Like other spectrometers, this spectrometer has the advantage of limiting analysis time by obtaining results with just one exposure. Using a spectrometer, a laser beam is directed at a region of tissue, with a reference beam aimed to a mirror.  An OCT spectrometer’s resolution can be .08 nm or less. The exceptionally low signal to noise ratios obtained using an OCT spectrometer increase reliability and throughput.

This spectrometer employs the highly efficient Volume Phase Grating (VPG) as the spectral dispersion element and an ultra sensitive 1024 pixel array detector as the detection element, thereby providing high-speed parallel processing and continuous spectrum measurement. This device uses a single mode fiber, then collimating it with a micro lans. This technique has flexible options for center wavelength and spectral bandwidth. This device features with easy to use GUI-based software for capturing and manipulating data. This device accepts single mode fiber optic inputs and customizable via grating inserts to match the wavelength of the user’s light source.

This device never requires alignment and can be customized for high resolution preference. Standard fabrication process used in this device is easily transferable. Spectrometer on chip solutions are robust, miniaturized optical engines designed for high performance measurement and at a fraction of size weight and cost of free space systems. This OCT device used in many different biomedical applications with retinal imaging being the most successful and the driving force behind much OCT development.  OCT uses low coherence interferometer in which light source is split between that that entering the eye and a reference path.

Hence, these are the features of the device and for purchasing an OCT spectrometer, always choose a reputed supplier that deals in high quality products.
