The Model 2010/M can operate as a fully-automated refractometer, providing high accuracy measurement of refractive index and index anisotropy for solid or liquid bulk materials and thick films in the index range 1.0 -2.6 without use of toxic or corrosive index matching fluids. This bulk material index measurement is not an option, but a standard feature provided with every system...

This option measures loss of optical wave guides by scanning a fibre optic probe and photodetector down the length of a propagating streak to measure the light intensity scattered from the surface of the guide. The assumption is that at every point on the propagating streak the light scattered from the surface and picked up by the fibre is proportional to the...

Metricon’s Model 2010/M system transforms prism coupling from an esoteric research technique into a routine laboratory analysis measurement. With the 2010/M, wave guide characterization data which typically requires a skilled professional an hour or more to collect with home made apparatus can now be obtained in 30 seconds or less in a format providing complete documentation of results and measurement...

EssentOptics, a leading producer of UV-VIS-MWIR spectrophotometers for optical coaters, sets a new benchmark for the effective wavelength range of this type of spectrophotometer instrument and announces the expanded Mid Wave IR (MWIR) range configurations for its Photon RT spectrophotometers. By Mid-wave Infrared (MWIR) we are referring to the 3 to 5 µm atmospheric window which is typically covered by detectors...

Pioneering the Optical Measurement segment with the unique UV-VIS-MWIR PHOTON RT spectrophotometer, EssentOptics continues to work closely with its customers worldwide and add new features improving product performance, measurement results and day-to-day work satisfaction. The upgraded PHOTON RT was showcased at the Laser World of Photonics 2015 exhibition in Munich, Germany (June 22-25, 2015). Throughout extensive field tests with our...

EssentOptics is proud to announce successful completion of two important projects in the United States and Israel for the supply PHOTON RT Universal Scanning Spectrophotometers. The spectrophotometers where installed, commissioned and put into operation at Lawrence Livermore National Laboratory (USA) and Rafael (Israel). Lawrence Livermore National Laboratory is presently the United States' leading research and development centre focusing on a broad...

The new version of PhotonSoft program features advanced capability to conduct group measurements of single and multiple substrates. Such function is of great value when determination of optimum angle of incidence for maximum optical performance is required. Example 1: Thin film polariser The thin film polarisers are often used to separate polarisation of incoming beam, e.g. laser beam. For appropriate...

Optical profilers are interference microscopes, and are used to measure height variations – such as surface roughness – on surfaces with great precision using the wavelength of light as the ruler. Optical interference profiling is a well-established method of obtaining accurate surface measurements. Optical profiling uses the wave properties of light to compare the optical path difference between a test surface and a reference surface...

ZYGO's Verifire™ Series of laser Fizeau interferometers represent a complete line of high performance metrology instruments for the measurement of plano, spherical and aspherical surfaces and material characteristics. The systems provide a variety of proprietary acquisition techniques to ensure optimum metrology in a wide range of environments. For acquisition in turbulent environments, ZYGO offers the DynaFiz interferometer. While all Verifire™ models can...

QPSI Technology Shrugs Off Vibration from Common Sources When image stabilisation became available on digital cameras, it vastly reduced the number of photos ruined by camera shake. The new technology eliminated the effects of common hand tremors, greatly improving image quality in many photo situations. In precision interferometric metrology a similar problem, environmental vibration, has ruined countless measurements, like the...
