Precision-Optical Engineering has unveiled a version of its Interfire II infrared interferometer, operating at 1.55 µm. A high-resolution near-IR converter from Applied Scintillation Technologies is inserted between a large-format lens and the camera to convert the 1.495- to 1.595-µm band to wavelengths detectable via standard CCD cameras, without fading or lag. A large-format AR-coated input window enables maximum image resolution to be transferred to the attached CCD camera. The system uses two laser diodes, one as a marker beam and one for the measurements, coupled into an optical fiber to deliver precise alignment. With a 35-mm aperture, zoom and focus systems, and remote control, it uses glass lenses and mirrors. The company says that the instrument produces a good signal-to-noise ratio and high sensitivity.
