BaySpec, Goodrich partnership yields next-gen OCT spectral engine

San Jose, CA and Princeton, NJ--Spectroscopy solutions provider BaySpec and Goodrich Corporation's ISR Systems' Princeton team (formerly Sensors Unlimited), a designer, developer and manufacturer of indium gallium arsenide (InGaAs) shortwave infrared (SWIR) imaging sensors and cameras, have announced that their successful collaboration has delivered a new optical coherence tomography (OCT) spectral engine that they say offers 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 2x improvement in the A-line rate to 92k lines per second while the Volume Phase Grating (VPG)-based spectrograph greatly enhances 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 2300:1 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 1.31µm SD-OCT, the system offers superior phase stability for Doppler or polarization-sensitive OCT. The 1.31 µm systems are perfectly-suited for the dental, cardiovascular, endoscopy, biological and biomedical related 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 4 weeks turn around. BaySpec provides calibration and factory alignment with any system order.

According to Doug Malchow, Goodrich's ISR Systems Princeton team's industrial product business development manager, "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. "

Eric Bergles, BaySpec's VP sales & marketing, says, "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".
