Ophir Optronics Solutions is a multinational company which sells optronics solutions. The company develops, manufactures and markets infrared optics and laser measurement equipment.Founded in 1976, the company has been traded on the Tel Aviv Stock Exchange since 1991, and is a constituent of its Tel-tech index. Headquartered in the Har Hotzvim industrial park in Jerusalem, Israel Ophir owns a 100,000-square-foot complex that includes the group's main production plant. Ophir has additional production plants in North Andover, Massachusetts and Logan, Utah in the US and sales offices in the US, Japan and Europe.In 2006, Ophir acquired Spiricon Group, a US-based company in the beam-profiling market. Ophir's sales increased sharply from $45 million in 2005 to $74 million in 2007.During 2007, Ophir established a Swiss-based subsidiary to market lenses and components for surveillance and imaging systems in Europe. In May 2010, Ophir acquired Photon Inc., another US-based beam-profiling company. Newport Corporation, a global supplier in photonics solutions, completed its acquisition of Ophir in October of 2011.Ophir Photonics Group The group manufactures, calibrates and sells a complete line of laser measurement instruments for analyzing and measuring laser power, energy, beam profile and spectrum used in industry, telecom, medical and scientific research. Products include reliable and accurate laser power and energy meters, laser beam diagnostic instrumentation, laser measurement tools and spectral analysis instruments, which comply with NIST calibration.Infrared Optics GroupThe Infrared Optics Group designs and produces optical lenses and elements for military, security and commercial markets. All manufacturing is done in-house, using automated CNC and patented Diamond Turning technologies. Ophir has expanded its optical and mechanical design department to offer lens assemblies and broadened its product lines to include the design and manufacture of optical elements for CO2 high power lasers used in industry for laser cutting and welding machines.3-D Non-Contact Measurement Group Optical Metrology Ltd., an Ophir subsidiary, has developed new non-contact 3-dimensional measurement systems using its patented conoscopic holography technology. Optimet sensors provide extremely precise 3-D measurements for applications in the motor, dentistry, electronics, steelworks, mechanics and aviation, quality control, in-process inspection and reverse engineering industries.In July 2008, the FIMI fund invested $23.5 million in Ophir in exchange for five millionshares of the company and 1.75 million warrants, exercisable within five years at $5.75 each.

Experts suggested that applying new diamond-like carbon multiple-layer coatings to front-surface forward-looking infrared lens assemblies reduced the Narcissus effect without compromising durability. Ophir Optronics Ltd., developed a new type of coating, called low-reflection hard carbon (LRHC) to achieve these objectives. LRHC was a multilayer coating with a DLC overcoat layer designed to have a low reflection. The DLC layer thickness had to be minimized to reduce internal absorption but to maintain a minimal thickness to achieve the required durability. Several coatings were designed on Ge, ZnS, and ZnSe substrates with an HC top layer to withstand severe durability requirements for the 8- to 12-μm region. Experimental results for a Ge substrate revealed that the average reflectance in the 8- to 11.5-μm range was 0.62 percent, with average transmittance of 94 percent in the same region. Source

Ophir Optronics | Date: 2010-06-10

A laser power meter incorporating an absorber disc with a peripheral thermopile ring, either continuous or segmented, and an additional temperature detection element in the central portion, that enables measurement of beam size. This detection element can be a thermopile element, generally a ring of smaller diameter than the peripheral thermopile used, and located closer to the center of the absorber disc. With this arrangement the beam size can be measured, in addition to measurements of the power and the position of the beam. Alternatively, this centralized detection element can be a single thermocouple junction located at the center of the disc, which acts as the hot junction of a thermocouple pair. The second or cold junction is effectively located on the disc close to the peripheral thermopile. Alternatively, two temperature measuring elements can be used, one at the disc center and one at the periphery.

A method for centering a circular optical element using a non-self-centering chuck adapted to grip the element at two grip strengths. The element is rotated in the chuck while measuring the lateral position of the elements outer rim with a probe. The positions of maximum and minimum run-out of the element as a function of its angular position are determined. Chuck rotation is stopped at an angular position with the maximum rim run-out positioned at a predetermined point. The grip of the chuck is reduced such that the element is still held in the chuck but can be moved in a lateral direction without damaging its surface. The element is moved in a direction connecting the predetermined point of maximum run-out and the axis of rotation of the chuck, in order to reduce the run-out of the element. The procedure is repeated until the desired centering is achieved.

Diamond Like Carbon (DLC) or Hard Carbon (HC) single layer coatings on optical substrates are commonly used. As a single layer, the resulting average reflectance in different spectral ranges (about 2.5% in the 3-5 μm region) needs improvements. We propose multilayer coatings having a DLC upper layer applied on Si, Ge and other materials. These coatings result in an average reflection of less than 0.5% in either the 3.4-5 μm or the 8-11.5 μm regions. The average transmittance in these regions is more than 97%. The durability is comparable to single layer DLC coatings. These coatings are suitable to front surface FLIR lens assemblies. The effect on the performance of a zoom lens assembly and the reduction of the Narcissus effect is shown. © 2012 SPIE. Source
