Optical Coherence Tomography
Optical Coherence Tomography (OCT)
An Optical Coherence Tomography (OCT) system uses low coherence interference to measure reflectance versus distance into a material. Light from a semi-broadband source (like a Superluminescent LED) is split into a reference arm (with a fixed mirror) and a sample arm (towards the material to be scanned). The reflected beams from the reference and sample arms are recombined and input to a spectrometer that records the interference pattern vs. wavelength. The periodicity of fringes in the interference pattern is directly related to the depth into the sample material through the Fourier Transform.
Products for Optical Coherence Tomography
Ibsen Photonics spectrometer and grating technology are ideally suited for Spectral Domain-Optical Coherence Tomography (SD-OCT) systems due to the following distinct benefits:
High efficiency (optical throughput) for both polarizations due to high efficiency transmission gratings
Compact size
Robust and athermal design
Customizable for multiple wavelength ranges
OEM integration friendly design
Ibsen offers the EAGLE OCT-S spectrometer which is very well suited for SD-OCT. Futhermore, we have extensive experience in designing and volume manufacturing of customized spectrometers.
Below is a short list of spectrometers we recommend for SD-OCT
