tEchnology proDucts Analysis, test and measurement
laser alignment kits Newport has released its Lakit Series, a family of laser power alignment tuning kits. Ideal for laser tuning and alignment in research setups, the kit includes the new 1917-r laser power meter and a broad selection of optical detectors, making it easier for the researcher to match the laser type. each kit contains an optical power meter, a detector, and the corresponding mounting assembly to simplify product selection, setup, and to reduce costs. the Lakit Series tuning kits utilise three
types of detectors: silicon (Si), germanium (Ge), or thermopile. they operate in wavelength ranges from 200nm to 10.6µm, and up to 100W average power. the 918D Series is designed for low power lasers (<2W/cm2) and operates in the visible or in the infrared spectrum. It features an integrated oD3 attenuator. the 818P Series thermopile detectors are
an ideal choice for measuring the average power for high-power lasers that operate both in continuous wave and pulsed modes. the broadband flat spectral response ranges from 0.19 to 11µm, with a high damage threshold and very high sensitivity to optical power.

interferometer offers accuracy and value
4D technology has introduced the AccuFiz Fizeau interferometer for measurement of precision optics. the compact AccuFiz interferometer offers an excellent combination of accuracy, quality and value, for surface shape and transmitted wavefront quality measurements of optical components and systems. the interferometer provides
high accuracy at mid-spatial frequencies, enabling optics manufacturers to measure polishing artefacts typically missed.
handheld flash probes
Gentec-eo has extended its Flash Handheld Laser Probes family of products with the introduction of the new Flash- IPL probes, specially designed for IPL sources. the Flash-IPL is configured to measure intense light pulses at slow repetition
Standard system features include a touch-
screen remote, fully motorised controls and tool- free height adjustment. the standard Smart Zoom ensures repeatable lateral resolution at all zoom settings. Included 4Sight wavefront analysis software features an intuitive interface and is easy to use. the AccuFiz product line offers a
selection of laser sources, aperture sizes, mounting configurations and accessories for a wide range of applications and budgets. optional Dynamic Interferometry capability lets users make measurements – despite
vibration and air turbulence – without an air table.

rates up to 350 J/pulse, with its unique single shot calibration. thanks to the calibrated apertures of 1cm2
, the user will get a direct
measurement of the fluence (J/ cm2
). Also available upon request,
a special model for large beams, with a 55mm Ø optical aperture.

lenses and optics Macro lenses for thermal cameras
Flir Advanced thermal Solutions has released two high performance macro lenses for use with its Sc645 and Sc655 thermal imaging cameras. Available in a choice of 2.9x and
5.8x magnification, the Flir close-up lens enables accurate temperature readings of small objects such as fuses, printed circuit boards and analysis of very small components and processes. the 2.9x close-up lens can resolve elements
as small as 50µm within a field-of-view of 32 x 24mm (40mm diagonal). the 5.8x lens operates over a larger field-of-view (64 x 48mm, 80mm diagonal) and can resolve elements as small as 100µm. the close-up lenses are manufactured
patterned optical coating technology
ocean thin Films now offers its Pixeltec patterned optical coating technology for Indium tin oxide (Ito) thin films. this lithographic patterning of optical coatings produces sharp features, while maintaining the high quality performance of sputtered Ito coatings, ideal for precision electro-optic devices requiring optically
to the highest quality standards and are easily connected to Flir thermal imaging cameras. the Sc645 and Sc655 are high-resolution
uncooled infrared cameras that offer high sensitivity and high functionality. both cameras provide a 640 x 480 pixel Ir resolution, as well as Gige and USb 2.0 HS compatibility. the cameras are ideal for infrared research, product development and non-destructive testing
applications. they can record thermal distribution and variations in real time, so heat patterns, dissipation, leakage, and other heat-related factors in equipment, products and processes can be identified.

improve beam homegenity
edmund optics has introduced a range of Laser Speckle reducers, which are ideal for a wide variety of beam homegenisation, 3D scanning, metrology, and interferometry applications. the devices remove local interferences and
greatly reduce speckle noise in laser systems. this is done by dynamically diffusing the laser beam. Diffusing angles of 1°, 10° and 20° are offered, providing maximum versatility for a wide range of uses. Laser Speckle reducers are compact for ease of handling and integration. they feature integrated drive electronics and provide vibration-less speckle reduction. Laser Speckle reducers utilise four electro-
transparent films that are electrically conductive. Pixeltec microlithography enables micron-
scale patterning of Ito and Index Matched Ito (IMIto) without the downsides of traditional etching or ablation processes. the Ito can be patterned with no damage to the substrate and other coatings.

optic polymers, which selectively move each Laser Speckle reducer's central diffuser along the X and Y axis to form a circular pattern of motion. As a result, the laser speckle pattern is adjusted to appear as a uniform distribution of light. to take advantage of maximum laser speckle reduction, the user would position the Laser Speckle reducers perpendicular to the laser beam and use a collimated laser source, with beam diameter equivalent to the Laser Speckle reducers' clear aperture.
