Optics can be as simple as a pair of glasses or contact lenses or as intricate as lens optimization techniques that can navigate multi-dimensional space.
The visual monitoring of manufacturing processes, optical quality inspections, the detection of surface defects and completeness checks for features on complex products have become essential in industry. At this, JENOPTIK Laser, Optik, Systeme GmbH (Jena, Germany) offers a standard range of high-precision lenses for sophisticated applications. Absolute precision, exceptional reliability and secure handling are the quality characteristics of the JENmetar™ Telecentric Measurement Lenses. The lenses in this series work on the tried and tested principle of telecentric imaging for measuring technology. They were specially developed for taking measurements in the quality control process and for image processing. The unity of function and quality in the JENmetar™ series ensures high reliability and reproducibility of the measurements particularly in industrial applications. The JENmetar™ brand mark stands for the warranty for the geometrical accuracy of moving or spatially extended objects due to strict telecentric principles, with an extremly low distortion and high image quality. Besides these characteristics, the JENmetar™ telecentric measurement lenses offer other key advantages: The specified optical parameters apply equally for all wavelengths in the visible spectrum up to the near infrared. There are no restrictions on the use of white light or color image cameras. www.jenoptik-los.com
Deposition Sciences, Inc. (DSI, Santa Rosa, Calif.) announces a line of transparent conductive coatings for use in the visible and near-infrared (NIR) spectral ranges. The new family of transparent coatings is compatible with DSI's dichroic filter technology, enabled by the patented Microdyn® sputtering process. This proprietary technology yields high performance, highly uniform, transparent conductive filters that remain extremely stable while withstanding high thermal loads and changes in humidity.DSI offers a wide variety of optical thin films that operate in the visible and near-IR wavelengths. These now can be combined with the new transparent conductive coatings and formulated to be broadband or spectrally selective, per customer requirements. The new conductive coatings with indium tin oxide, induced transmission silver, and induced transmission gold, all deliver high transmission within selected wavelength ranges from 400nm to 2500nm. These coatings can be applied onto a wide variety of substrates, including silicon, germanium, zinc sulfide, zinc selenide, and most glass types that are compatible with the visible to near-infrared spectral regions. www.depsci.com
Moritex (San Jose, Calif.) announces the introduction of the new ML-0310VF Variable Focus Macro Lens. Designed for use with large format megapixel CCD and CMOS cameras (up to 15.2 x 15.2mm sensor size) Moritex's new Macro Lens delivers the required accuracy to inspect large area components in high resolution. Incorporating a varifocal zoom and variable iris the new Macro Lens provides users with the flexibility to adjust both zoom and focus. This flexibility, coupled with the ability to achieve a variable depth of field, enables the ML-0310VF Macro Lens to deliver leading -edge performance for applications including PCB and wafer inspection, electronic part inspection, automotive part inspection and solar panel inspection. ML-0310VF Macro Lens was developed to provide customers with an optimised lens for inspecting wide areas at high resolution at short working distances (75 -145mm). www.moritex.com
Ocean Optics (Dunedin, Fla.) introduces the Optical Transmittance Spectrometer (OTS), a compact system designed for accurate, repeatable real-time transmittance measurement of optical lenses and other optical components. The OTS is particularly useful for measuring tint color, photopic transmittance and UV cutoff of ophthalmic lenses and for characterizing photochromic, electrochromic and sun lens materials. The OTS covers the 380-1000 nm wavelength range and accepts samples from 10-76 mm diameter and 25.4 mm thickness. The system comprises several components: High-resolution miniature linear CCD-array spectrometer configured for 380-1000 nm; high-power, 20-watt tungsten halogen light source; fiber optic integrating sphere for collecting signal transmitted through the sample; Optics for improved beam collimation and spectral sensitivity distribution; sample fixture (z-stage) to hold sample in place and exclude ambient light and short optical fiber to channel signal from the integrating sphere to the spectrometer. www.oceanoptics.com
