Abstract: The present disclosure provides a near-infrared absorbing filter, including an absorbing type infrared filtering medium having opposite first and second surfaces; an organic coating layer formed on the first surface of the absorbing type filtering medium for absorbing infrared rays; a first multi-layered film structure formed on the organic coating layer with the organic coating layer disposed between the first multi-layered film structure and the absorbing type infrared filtering medium; and a second multi-layered film structure formed on the second surface of the absorbing type infrared filtering medium. The near-infrared filter of the present disclosure is able to reduce the wavelength difference of T50 and T20 of the incident light within the range of from 0 to 30 degrees to less than 5 nm, thereby reducing chromatic aberration effectively and reducing ghost images of infrared reflections. The disclosure further provides an image sensor including the near-infrared absorbing filter.

Abstract: A multi-pass-type Faraday rotator useful in an optical isolator is provisioned with high-efficiency, high-field permanent magnets formed with minimal magnetic material. A high magnetic field is generated by two sets of magnets attached to outer pole plates that are mirror images of each other. Like-type poles of the magnets in each set are disposed against each other above and below the beam path plane of a multi-pass Faraday optic. Each set of magnets is formed of a central block of magnetic material with magnetization oriented substantially parallel to the multi-pass beam path on the Faraday optic, adjoined by adjacent blocks of magnetic material with magnetization oriented substantially perpendicular to the central magnet block and with like poles to the central magnet block where the magnets border the multi-pass Faraday optic.

Abstract: Transparent heat-conductive layers of significant thickness are bonded or adhered to opposing optical faces of a Faraday optic to form a Faraday optic structure that can be used with beam-folding mirrors and an external magnetic field to form a multi-pass Faraday rotator with minimal thermal gradient across the beam within the Faraday optic. The transparent heat conductive layers conduct heat through the Faraday optic substantially parallel to the beam propagation axis for each pass through the Faraday optic structure and thereby reduce thermal gradients across the beam cross section that would otherwise contribute to thermal lens focal shifts and thermal birefringence in the Faraday optic structure. The multi-pass Faraday rotator of this invention is suitable for use with any device based upon the Faraday effect such as optical isolators, optical circulators and Faraday mirrors that are scalable with beam size to power levels in excess of 2 kW.

Abstract: A LARGE NUMBER OF LIGHT-TRANSMITTING CONVENTIONALLY CLAD GLASS RODS ENVELOPED OR SUPERCLADDED WITH A BONDIING MATERIAL ARE GATHERED, ALIGNED, HEATED AND STRETCHED WHILE MAINTAINED IN ALIGMENT TO REDUCE THEIR DIAMETER AND BOND THEM TO EACH OTHER TO FORM A BUNDLE OF MUTUALLY ALIGNED FIBERS. THE MATERIAL FOR THE LIGHT-TRANSMITTING RODS IS SELECTED SO THAT IT WITHSTANDS A CHEMICAL SOLUTION IN WHICH THE BONDING MATERIAL IS SOLUBLE. INTERMEDIATE PORTIONS OF THE ROD ARE IMMERSED IN THE SOLUTION TO DISSOLVE THE BONDING MATERIAL FROM BETWEEN THE INDIVIDUAL FIBERS WHILE THE ENDS OF THE FIBERS REMAINS EMBEDDED THEREIN, FIXED WITH RESPECT TO EACH OTHER AND IN THEIR ORIGINAL, MUTUALLY ALIGNED POSITION.
