Vertical integration defines Wasatch’s approach to OCT
spectrometer supply: our patented, industry-leading VPH gratings sit at the
core of a broad, pre-configured Cobra series lineup. Built on opto-mechanically
robust designs, these units deliver high SNR and strong roll-off performance
for clear imaging. Add OCT-specific software development kits, internal
expertise, and high-volume manufacturing, and Wasatch becomes a dependable
partner for application needs at any scale.
What Sets Us Apart:
The reflected light in OCT is very low intensity; therefore, a highly sensitive spectrometer will substantially improve image quality. And since OCT uses a Fourier transform of the spectrum, every wavelength in that spectrum is important. The more uniform the spectrometer response is with wavelength, the better the image quality. Use of a high efficiency, broadband grating in the spectrometer is very important, and Wasatch Photonics offers the industry standard, patented HD gratings.
OCT is an interferometric technique, often using fiber optics for transmission. This makes the system highly sensitive to polarization changes. While most components in a spectrometer are polarization-insensitive, gratings that have strong polarization dependence are not suitable for OCT imaging. Wasatch VPH transmission gratings designed for OCT have very low polarization sensitivity, which is why Wasatch Photonics is the leading supplier of OCT gratings worldwide.
Off-the-shelf optics often fail to deliver high clarity OCT images because excellent optical resolution is essential for low roll off and thus good imaging depth. The spot size of light imaged on each camera pixel must be small to avoid spreading to neighboring pixels, and this must be true for the wide range of wavelengths used in the spectrometer. At Wasatch Photonics, we design and source custom lens sets that match our spectrometer designs perfectly, yielding optimized spectrometer performance for OCT at all wavelengths that far outperforms use of off-the-shelf lenses.
While careful optical design can significantly reduce roll-off in an OCT spectrometer, crosstalk between camera pixels can limit the performance that can be achieved. At Wasatch Photonics, we use high sensitivity, low crosstalk cameras such as the e2v OctoPlus camera in our Cobra-S spectrometers
Data transfer from the camera used to collect OCT spectra may be achieved through a camera link card or over USB cable, depending on the camera model. Camera link communication allows for faster scan speeds and are a more stable platform, but it requires purchase of a camera link card and a computer in which to install it. USB 3.0 communication, on other hand, allows any computer to be used for scanning, but only up to 130 kHz; it also requires camera-dependent software development. At Wasatch Photonics, we offer both options to give you the flexibility you need.
The cameras used in OCT spectrometers have many other uses, and come with extensive, complex manuals of commands for control and data acquisition that can be time-consuming to sift through. That’s why Wasatch Photonics OCT spectrometers come with software development kits – a set of streamlined, OCT-specific commands and sample GUIs that allow you to begin acquiring images in just 30 minutes with any OCT spectrometer we offer, saving days to weeks of software development time with guaranteed results.
Over the past decade, we have worked with a wide range of OCT applications and systems, building the expertise to help you identify the optimal system design for your specific needs. We help you to determine when to use standard products and when a custom solution will best accelerate your timeline and elevate performance.
Our team has extensive experience evaluating the many light sources, probes, and peripherals available on the market to help maximize system performance. Combined with our cross-disciplinary application knowledge and hands-on testing, this perspective allows us to solve new challenges with practical and innovative solutions.
