- 4/04Introducing new hex-shape fiber heads with built-in lens
Being a global leader of fiber optical sensors we have enhanced our portfolio on optical fibers. The new hex shape fiber series with built-in lens combines significant performance enhancement with user-friendly mounting even in tight spaces. Offered at an affordable price they are an attractive - 4/04E3FC - New detergent resistant Photo-electric Sensors
The new M18 shape E3FC family is best fit for tough environments in food processing industry with regular cleaning cycles. Protected by a full-body SUS316L housing the sensor is further filled with epoxy resin at the connector/cable back-end, which guarantees superior protection against - 27/11Diffraction effects in radiometry
Essentially, classical radiometry relies on geometrical optics (to relate source radiance), geometrical aspects of an optical layout, and the irradiance at the detector. One considers the propagation of radiation from points on the surface of the source to points on the surface of the - 27/11Detector metrology
Improved detector technology in the past two decades has opened a new era in detector metrology of optical radiation measurements. Lower calibration and measurement uncertainties can be achieved with modern detector/radiometer standards than traditionally used source standards (blackbodies and - 27/11Absolute cryogenic infrared radiometry at the LBIR facility
The Strategic Defense Initiative (SDI), and subsequently the Ballistic Missile Defense Organization (BMDO) of the U.S. Department of Defense (DoD), has motivated NIST’s work developing calibration methods and standards for space-based sensors used in missile defense. These on-board sensors - 27/11Transfer radiometers and reference detectors
Use of these radiometers depends on a primary standard detector and a secondary transfer detector. We generally employ an absolute cryogenic radiometer (ACR) as the primary standard detector to calibrate the transfer detector, a Si:As blocked-impurity-band (BIB) detector. The transfer detector is - 27/11Infrared cryogenic blackbody broadband calibration
The broadband chamber and the spectral calibration chamber at the LBIR facility are used for calibrating the customer cryogenic blackbodies. The chambers are cooled by closed cycle helium gas at 20 K to provide a background equivalent to space. The absolute cryogenic radiometers (ACRs) in these - 27/11cryogenic infrared radiometry at the LBIR facility

After the Second World War and the partition of Germany, Carl Zeiss was also separated. In addition to the traditional site in Jena, there was now a new firm in Oberkochen. It was not until 1952 that the Optical Measuring Instruments division was able to offer the entire pre-war product line - 27/11Introduction of an Inductive Pickup Sensor
An inductive pickup sensor employing an isolation transformer to achieve substantially improved immunity to capacitively-induced cross-talk signals is provided. A magnetic pickup coil is coupled to a spark plug wire to receive a spark signal. The spark signal developed
