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.
