BaySpec, Goodrich Deliver OCT Spectral Engine

BaySpec Inc. and Goodrich Corp,'s ISR Systems' Princeton team (formerly Sensors Unlimited Inc.) have announced that their recent collaboration has delivered a new optical coherence tomography (OCT) spectral engine with breakthrough speed, compact size and high optical throughput.

BaySpec's DeepView spectrograph, together with Goodrich's new SU-LDH2 linescan OCT image sensor camera, offers a 2× improvement in the A-line rate to 92,000 lines per second, while the volume phase grating (VPG)-based spectrograph greatly enhancing throughput. In addition to the high performance optical resolution, the camera's higher scanning speeds enable freeze motion artifacts in the patient and in the interferometer.

With a dynamic range of more than 2300 to 1 for high line rates, the new SU-LDH2 camera is ideal for high-end OCT systems for the near infrared beyond 1000-nm OCT applications. At 1.05 μm, the system captures detailed 3-D volumes of the retina, nerve head and choroid layer between blinks of an eye. For both 1.04- and 1.31-µm spectral-domain (SD) OCT, the system offers superior phase stability for Doppler or polarization-sensitive OCT. The 1.31-μm systems are suitable for dental, cardiovascular, endoscopy, biological and biomedical applications.

BaySpec's NIR DeepView spectrographs feature fast f/2 optics and high-efficiency transmission VPGs. Any custom center and total wavelength range can be requested for optimal resolution with standard lead times of only four weeks, according to the company. BaySpec provides calibration and factory alignment with any system order.

"The combination of our InGaAs camera and BaySpec's compact spectral engine system, optimized for OCT applications, has already raised great interest. This will make SD-OCT even more enabling and accessible to the research community and industrial markets and will permit a wide variety of new biomedical and industrial OCT applications in the near future,” said Doug Malchow, Goodrich's ISR Systems Princeton team's industrial product business development manager.

"The performance-to-price ratio and ruggedness of this system will enable new portable, OCT systems that can be shuttled around doctor's offices with ease. We also expect this breakthrough to lead to a host of new industrial applications, too," added Eric Bergles, BaySpec's vice-president of sales and marketing.
