FILTER PROTECTS IMAGER DURING


LASER PROCESSING The compact and robust thermoIMAGER TIM M1 thermal imager from Micro- Epsilon is suitable for temperature measurement applications in metal processing, including the temperature monitoring of metal hardening and forming processes. The addition of an integrated notch filter, however, prevents damage to the detector when the camera is exposed to the lasers used in welding processes. Lasers used in welding and laser machining have a wavelength in the centre of


the TIM M1’s wavelength range and, if left unfiltered, would cause damage to the thermal imager’s CMOS detector. The integrated notch filter blocks these lasers at 1064nm. As a result, the camera can now be used in laser processing applications such as laser welding, laser additive machining and brazing. Additional features of the camera include a high speed (1kHz) linescanning mode,


which allows the detection of extremely small material defects, including cracks on fast-moving metal objects such as steel bars, slabs, pipes and rails. The M1 has a high resolution CMOS detector with 764 x 480 pixels, a


temperature measuring range of 450˚C to 1800˚C and, for harsh environments, can be supplied with a large stainless steel air or water-cooled housing that can operate in 315˚C ambient temperatures. It is powered and operated via a USB 2.0 interface, providing temperature images and profiles of a target area. Of additional benefit the M1 is supplied with the licence-free TIMConnect


operating and analysis software as standard, which includes a variety of process control features, including an ‘image merging’ function.

Rugged in design, the TiS Performance Series Infrared Camera range from Fluke offers up to 320 x 240 resolution and an easy-to-use interface. As a result, it produces high quality focused images that enable users to produce better analysis and presentation of results which can also be shared with colleagues off-site wirelessly, via a smartphone or tablet, using Fluke Connect technology. According to the company, until 31st December 2016, selected models are now more affordable. With the TiS range’s sharply focused image,


there is distinct contrast between areas of varying thermal energy on the surface being inspected. This allows the individual pixels to clearly report the intensity of the energy being focused on them. An additional feature of the camera is


IR-Fusion technology, which combines a visible light and an infrared image into one, giving better clarity. More detail can be seen by adjusting the level of infrared and visible light blending in AutoBlend mode, while ‘picture-in-picture’ helps to clearly identify the exact location by providing the centre part of the display in IR and the remainder of the image in visible light. Also included is SmartView software, which provides a suite of advanced tools to view, optimise, annotate, and analyse infrared images, and generate fully customisable professional reports.

CAMERA SEES ‘INVISIBLE DANGER’


European scientists are developing a surveillance camera using new photonics technology that will dramatically reduce coastal rescue times in low visibility conditions, target Greenhouse gasses and keep people safer on the Underground. The camera uses Multi Spectral


Imaging, a process that captures the same image at different frequencies from the electromagnetic spectrum. Certain combinations of multi spectral images can reveal information that humans cannot see, such as invisible, poisonous or Greenhouse gasses, or fire sources through dense fog. The device deploys the latest photonic


sensing technology, featuring a multi- aperture, multi sensor camera capable of capturing several wavelengths simultaneously in one place. Coordinated in Spain, the SEERS, or ‘Snapshot spectral imager for IR surveillance’ project, has received a grant of €3,750,535 from Horizon 2020 via the Photonics Public Private Partnership. Project coordinator, Anton Garcia-


Diaz, said: “The SEERS project aims to deliver MSI technology in an extended infra-red domain at under €40,000, with improved persistence and gas identification capabilities.”

PORTABLE HIGHLY SENSITIVE CAMERA LAUNCHED


A portable, highly sensitive infrared camera with fast frame rates, the GF335 Broadband Infrared Camera from FLIR Systems combines cooled MWIR detector technology with a compact handheld design. This is a low noise, cooled thermal camera capable of detecting faint heat signatures. It has a cooled 3–5 µm InSb detector and is able to produce ultra sharp thermal images; while its high sensitivity of <15mK and high accuracy of ±1˚C allow users to detect very subtle temperature differences. In addition, on-camera video


recording, playback and analysis are made easy and temperature calibrated snapshots or movies are recorded


to the removable SD card. For longer recordings, non-radiometric thermal MPEG-4 or visual videos can also be stored. Additional features include a powerful eight to one digital zoom and it can be mounted on a tripod with data streamed directly to a computer running ResearchIR. The camera is said to be suited to a wide range of applications, including use on test ranges, non-destructive testing, research and scientific applications.

NEW RANGE OF IMAGE SENSORS INTRODUCED


New from ON Semiconductor is the 8-megapixel KAE08151 image sensor, the second device to use the company’s ITEMCCD technology. This, the company explains, uses the same sub-electron noise floor and imaging versatility as the existing 1080p resolution KAE02150 image sensor. With a 22mm diagonal (4/3 optical format) that matches the imaging path of professional microscopes, the


KAE08151 directly targets high resolution microscopy and scientific imaging applications operating in lighting regimes that can range from sub-lux to bright-light imaging. In addition, a new packaging option is available for both devices in this family which incorporates a thermoelectric cooler (TEC) directly in the package design. ITEMCCD devices combine two established imaging technologies with an output structure that


enables a new class of low-noise, high-dynamic range imaging. The KAE08151 is sampling in Monochrome and Bayer Colour configurations in a CPGA-155 package, with samples incorporating an integrated TEC available in the first quarter of 2017. The KAE02150, already in production, is now sampling in a CPGA-143 package that incorporates an integrated TEC.
