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...

Description: SLS Optics used a Zygo Verifire-AT system to characterise coated flat optical surfaces used in their etalons to better than 1/150 wave.

Recommended Product: Zygo Verifire

SLS Optics  are based on the Isle of Man and were founded in 1995. They make products based on etalons that use coated flat surfaces that are flat to better than 1/150 wave. Since its inception SLS Optics have been using the Zygo GPI-XP system to measure these optics with great success. However for some measurements related to mechanical wedge, the GPI-XP was reaching the limit of its capabilities.

With both expansion and better measurement capabilities in mind SLS Optics looked to Zygo for a better solution. This was found in the VeriFire AT 1000. The VeriFire AT has the "Ring of Fire" technology that reduces coherent artifacts and is more noticeable when measuring such high quality optics. Also, the VeriFire AT 1000 uses a 1024 x 1024 CCD camera for higher spatial resolution and higher data density which in turn leads to more repeatable wedge angle measurements for very parallel surfaces. SLS has specified the highest lateral resolution imaging option available (1k x1k) which underlines its commitment to the tightest performance levels and the very best in Quality Assurance in the production of its ultra-flat precision optics.
