Wasatch Photonics has announced its new OCT spectrometer, Cobra-S, offering ultra-high speeds of 250000 lines per second and enhanced roll-off performance for deeper sample penetration with the highest image clarity.
The Cobra-S can be designed into near-infrared OCT systems for research and OEM applications. A part of Wasatch Photonics’ Cobra spectrometer line, the Cobra-S is designed for a variety of spectral-domain OCT applications, including ophthalmology, dermatology, angiography, oncology and industrial use.
The maker expects the speed of this OCT spectrometer to be a “major game-changer in optical coherence tomography.”
At 250 kHz, the Cobra-S gives the user line scan rates at least two to three times higher than other current commercial spectrometer models. With a design to provide improved roll-off performance resulting in deeper imaging and higher image quality, the spectrometer offers increased accuracy with superior data, according to the company.
The spectrometer package includes available feature options for athermal opto-mechanics to maintain the performance level over a wide range of operating conditions. The compact and modular design was developed with research applications and OEM compatibility in mind.
Cobra-S is available in multiple configurations to cover different wavelength regions for the utmost flexibility and function.
With most spectral-domain OCT spectrometers providing high-resolution and good phase-stability, there are drawbacks regarding speed and sensitivity fall-off with depth. The company says the Cobra-S addresses both sensitivity and fall-off issues while maintaining very high resolution and phase-sensitivity in this technology.
The company adds that Optical Coherence Tomography (OCT) is currently one of the fastest growing optical diagnostic technologies and is becoming a staple tool in ophthalmology offices. Use in cardiology, dermatology and non-destructive industrial and laboratory testing practices has been growing at a rapid pace.
