OCT spectrometers
for system integration
Choosing the right OCT spectrometer for your application
Instruments for Spectral Domain Optical Coherence Tomography (SD-OCT) consist of a broadband light source, a 2D galvo scanner, an interferometer, and an OCT spectrometer. Depending on your application, there are many things to consider when choosing the right OCT spectrometer.
While ophthalmology retinal scanning is a major application for SD-OCT, there are many other uses that require different wavelengths and optical bandwidths. In general, SD-OCT systems must resolve interferometric fringe patterns in a large number of scan points on the sample with as low roll-off of the depth measurements as possible.
To support this, our OCT spectrometers offer the market’s highest sensitivity and best diffraction-limited resolution, with Modulation Transfer Functions (MTF) optimized to make optimal use of the integrated high-speed line-scan camera. This results in OCT spectrometers offering industry-leading roll-off in compact form factors, for integration into high-performance systems at a competitive cost.
OCT spectrometer sensitivity and roll-off
The high sensitivity of our OCT spectrometers is obtained through in-house manufactured transmission gratings with the highest diffraction efficiency on the market, often >95 % for the entire OCT bandwidth.
We have produced OCT spectrometers covering bandwidths from 60 to 300 nm with detectors of 1024, 2048, or 4096 pixels. Our focus is on performance when building fully customized spectrometers or adapting existing solutions to meet your needs. Our spectrometers offer best-in-class roll-off and sensitivity, enabling record high-quality OCT images.
