Request InfoWasatch Photonics Inc.Wasatch Photonics Inc. has released the HD 1800 l/mm volume phase holographic transmission grating for optical coherence tomography. The device exhibits a wide bandwidth and offers peak diffraction efficiencies above 80%. The company says that the product resolves the problem of narrow bandwidth- and polarization-dependent losses. The gratings are holographically exposed. They are centered at 850 nm and have an antireflection coating.See full productRelated content from Photonics MediaPRODUCTSPromoted Content January 2024 IssueUltrafast Optical Coherence Tomography (OCT) with Phantom High-Speed CameraOptical coherence tomography (OCT) is a noninvasive/nondestructive imaging technique.
