Established in 2000 Wasatch Photonics produces the world’s finest volume phase holographic gratings and spectroscopic instruments for retail and OEM customers. With this knowledge Wasatch has also specialized on the development and manufacturing of products for optical coherence tomography. Wasatch offers complete OCT systems as well as a line of confogurable modular components, e.g. spectrometers and probes, for customers that want to build highly specialized systems by themselves.
Wasatch Photonics’ Cobra OCT spectrometers fit a surprising amount of resolution, performance, and value into one small box. Beginning with our world-class volume phase holographic gratings, we’ve applied our expertise in spectroscopy to the unique needs of optical coherence tomography (OCT). The compact, high-throughput spectrometer designs provide exquisite detail at depths where other SD-OCT spectrometers struggle.
Ideally suited for use in both research and OEM applications, Cobra spectrometers offer many clear advantages over other devices: compact size, high throughput, minimal polarization dependence, optimal camera design and excellent roll-off performance. The Cobra spectrometer line’s unique engineering and optical design allow us to provide all of these features at a surprisingly affordable price, simplifying the decision of buy vs build.

A line of compact, high performance OCT probes for integration into any system. The engineers at Wasatch Photonics have applied their expertise in spectroscopy, optical & electronic design, and system integration to create superior tools to help you build the exact OCT system you need, faster.
The wide variety of off-the-shelf OCT probes include models that go from handheld to mounted in seconds, scan at 20 or 200 Hz, or look your sample straight in the eye. Each design combines innovative optical design with robust electronics for precise focusing, repeatable x-y-scanning, and high-transverse resolution at working distances >20 mm. Flexible enough for research and robust enough for OEM, we offer fiber-coupled probes that integrate easily with any OCT system.
Take advantage of the rigorous testing and optimization at the system level to expedite one of the most challenging and critical aspects of OCT system design. Have a specific application? Our ultracompact probes allow you to get closer to the sample without compromising performance. Working with bovines? The point & click operation of our animal retina probe makes it easy.
Our modular OCT probes can be used for OCT imaging at 800, 1050, or 1300 nm in research, industrial and OEM solutions.
Looking for easy to use yet powerful software for OCT system control, image capture, and processing? WP OCT software offers unique features to support custom system development, using our components or your own. We provide low-level control and access to all the acquired data, giving you all the tools you need to visualize, acquire and process optical coherence tomography (OCT) data. The software offers modes for 2D and 3D visualization and acquisition. The operator gets a live feed of the OCT image and simultaneously a view of the surface of the sample with high-resolution color camera. By positioning the scan arrow on the surface image the location of the OCT scan can be easily selected.
The image on the screen can be saved in the working directory by a single mouse click. WP OCT software has a unique record feature that allows user to save the past few frames to the disk. This avoids loss of useful data, and allows brief events to be captured. The WP OCT software not only allows standard image formats like .tiff and .png, but also supports medical device standard DICOM (Digital Imaging and Communication in Medicine).
3D Imaging
WP OCT software allows the user to collect three-dimensional OCT data, up to 1024 x 1024 x 1024 pixels. This volume can be visualized in the preview mode and again with a single click by the user. WP OCT software also has custom features to collect volumes of even larger size when needed. The acquired images can be saved as TIFF stacks or in a volume format like .vti. The images can be loaded back into OCT software for visualization. The visualization features allows for volume rendering from different perspective as well as scanning through different planes of the volume. As in 2D mode, the volume to collect is selected by defining the region in the surface image.

Custom Image Processing Plugins
WP OCT software allows user-defined plugins for the custom image processing methods. These plugins can either be entirely developed by the user or Wasatch Photonics can develop custom methods on user-defined algorithms and specifications. The software comes by default with plugins for standard filtering, stack averaging and segmentation. It is important to note that the software uses the GPU to increase the speed of the processing for faster image display and refresh.
Custom Scan Patterns
The most commonly used method to scan the focused beam for OCT image capture is raster scanning. However, certain scenarios and applications require more complicated scan patterns. WP OCT software not only provides standard raster scanning but also additional scan patterns of interest like circular and spiral scans. In addition, WP OCT software allows the user to define custom patterns programmatically. This variety in scanning is crucial for researchers looking to push the limits of standard OCT.
Imaging Systems
Optical coherence tomography is a 3D imaging technology used in a variety of applications including retinal imaging, optical biopsies, and for material and chemical inspection. OCT provides an extremely high-resolution image, on the order of 2-20 μm and it provides imaging depth of up to 2-3 mm in a scattering medium. OCT imaging is rapid, and can easily achieve video rate imaging. Wasatch Photonics OCT solutions provide our customers with a versatile turn-key system. We have the know-how to customize each system to each unique application. Our vertically, integrated design, and in-house OCT expertise makes us the preferred choice for both research and OEM applications.
