Online — “Light sources and detectors in the mid-infrared have been inferior to those in the visible or near-infrared, in terms of power, bandwidth, and sensitivity, severely limiting the performance of infrared experimental techniques.”

This article demonstrates the generation of femtosecond radiation with up to 5 W at 4.1 micrometers and 1.3 W at 8.5 micrometers, corresponding to an order-of-magnitude average power increase for ultrafast light sources operating at wavelengths longer than 5 micrometers.

The presented concept is based on power-scalable near-infrared lasers emitting at a wavelength near 1 micrometers, which pump optical parametric amplifiers.

In addition, both wavelength tunability and supercontinuum generation are reported, resulting in spectral coverage from 1.6 to 10.2 micrometers with power densities exceeding state-of-the-art synchrotron sources over the entire range.

WEBINAR: THERMAL CHARACTERIZATION OF POLYMERS

USING SETARAM ANALYZERS & CALORIMETERS

Setaram WebinarTuesday, April 24th 2018

Online —  Thermal analysis techniques are typically applied to the study of polymers and plastics whether they are applied to their thermal, structural or compositional characterization.

The webinar will introduce examples of application of DSC (differential scanning calorimetry), TGA (thermogravimetric analysis), EGA (evolved gas analysis), microcalorimetry and manometry related to glass transition, crystallinity, thermal stability, and sorption capacities of polymers.

Custom MIL-SPEC Lenses

MIL-SPEC lens offer temperature resistance

MIL-Spec Lens in useChesham, UK — Resolve Optics is a leading supplier of bespoke Military specification (MIL-SPEC) lenses that offer many advantages over regular off-the-shelf commercial grade lenses.

In different military scenarios – lenses can also be subject to extremes of temperature, for instance the temperature for aerial photography is often less than -30 °C, the temperature on the deck of a ship or for vehicles operating in the desert can often be higher than 50 °C.

Producing a lens or lens system for military use requires careful consideration of its resistance to vibration, shock, temperature and water ingress in addition to ensuring high reliability and top performance. Read more Custom MIL-SPEC Lenses

Smart Leak Detection for Oil and Gas Pipelines

IntelliView’s DCAM w/FLIR A65 thermal camera

FLIR A65 Thermal CameraMeer, Belgium — FLIR Systems has published an application note that describes how IntelliView, a Canadian specialist video analytics company, developed a smart camera solution based on a FLIR thermal camera to remotely automatically monitor oil pump stations for leaks.

Although pipeline leaks often start small, late detection and identification of leaks can be detrimental. For an oil and gas company, delayed detections can cause millions in financial losses, as well as damage to reputation and the environment.

In an effort to avoid these loses, many pipeline operators are taking a more proactive approach to maintaining the safety of their infrastructure and securing high-risk areas from potential leaks.

The application note describes IntelliView’s DCAM (Dual Camera Analytic Module) leak detection solution, a compact combination of visual and FLIR thermal cameras with built-in proprietary leak analytics, wireless connectivity and automatic climate control.
