Designing athermal lenses for LWIR systems
Introduction Due to advances in materials and manufacturing technologies, the vast majority of lenses used on long-wave infrared (LWIR) cameras are simple: One- or two- element designs with an emphasis on low-cost manufacturing. One effect of this is that most of these cameras are supplied without …

Highlights

Umicore’s revenues were slightly down compared to the first half of 2013 as a result of volume growth being offset by strong metal price and currency headwinds. Recurring EBIT was down 15% due to lower metal prices, currency headwinds and higher depreciation charges, partly offset by cost reductions.
Umicore, Pioneers in Closing the Loop, at Green Week 2014

Brussels, 4th June 2014. Umicore will participate at Green Week, the biggest annual conference on European environment policy, taking place from 3rd to 5th June in Brussels. This year’s theme ‘Circular Economy, Resource Efficiency & Waste’ fits closely with Umicore’s core activities.

Umicore will showcase its...
Methodology for lens transmission measurement in the 8-13 micron waveband: Integrating sphere versus camera-based

Article shared under SPIE's Green Open Access Policy. Available here.

Authors: Norbert Schuster,  Jan Verplancke, Bergeron Salethaiyan, John Franks, Umicore Electro-Optic Materials (Belgium)

ABSTRACT

Transmission is a key parameter in describing an IR-lens, but is also often the subject of...
Depth of Field in Modern Thermal Imaging

This text is an abstract. The full text is available at the SPIE Digital Library.

Modern thermal imaging lenses for uncooled detectors are high aperture systems. Very often, their aperture based f-number is faster than 1.2. The impact of this on the depth of field is dramatic, especially for narrow field lenses. The users would like to...

Update regarding the accident at Olen site

Brussels, 5th of February 2014. Umicore, together with an external expert, has examined the cause of the tragic accident in Olen on 23 January in which two Umicore employees lost their lives. A preliminary report has been submitted to the Health and Safety Inspectorate.

The initial findings indicate that an unexpected accumulation of...
Quantitative comparison of the chalcogenide glass GASIR with Germanium and Silicon for use in LWIR sensor lens design

This text is an online preview. The full version is available as a PDF download.

The cost of a lens is to a large extent determined by the number and complexity of the optical components. Requirements such as resolution, focal length and f-number drive the size and number of elements. This is true especially for imaging optics,...
5.000 Euro für das Albert-Schweitzer-Kinderdorf in Hanau – Umicore unterstützt die Multifamilientherapie

Hanau, 04. Dezember 2013. Kinder und Familien in schwierigen Lebenssituationen zu helfen, ist das Ziel des Albert-Schweitzer-Kinderdorfs (ASK) in Hanau. Dieses Anliegen wird von der Materialtechnologie-Gruppe Umicore seit mehreren Jahren nachhaltig unterstützt. Auch die diesjährige Weihnachtsspende in Höhe von 5.000 Euro kommt...
Umicore’s Electroplating business makes LEDs shine brighter

Umicore is not only a leading recycler, producer of catalysts and of rechargeable battery materials but also a key producer of sophisticated material for LEDs.  LEDs (Light Emitting Diodes) are semiconductor devices that glow when an electric current is passed through it. Umicore’s electrolytes are used as coating for LED carrier...
Two-lens designs for modern uncooled and cooled IR imaging devices

 This text is an abstract. The full text is available at the SPIE Digital Libary.

In recent years, uncooled, or thermal, detectors with a 17µm pixel pitch have become well-established for use in various applications. Examples of applications include thermal imaging in cars for driver’s vision enhancement. This has...
