Black body radiation is the emission of electromagnetic energy by an object which is in a thermodynamic equilibrium. The blackbody emits an amount of energy depends on its temperature, with ideal blackbody absorbing and re-emitting all the incident radiations it receives at any wavelength.

Thermal imaging cameras comprise a vitally important technological category within military avionics, but they can only be used properly if they are calibrated and tested before being deployed. One of the simplest ways to carry out infrared measurement within the confines of electro-optical test systems is to use specially developed targets.

With the coronavirus pandemic still raging around the world, the mandate is clear: follow the necessary protocols and focus on prevention than cure. For customer-facing businesses/organizations, this involves body temperature screening, spatial distancing, activating heightened hygiene measures, and setting up a Covid-19 responder. While most of these are fairly manageable, the body temperature part can get tricky.

The sky is a large blackbody radiation source. The emitted sky radiation covers all electromagnetic spectrum including the absorption wavelengths of a R-134a gas. The above infrared picture shows an image of a cloud. It can be a dust cloud that reflects the sky radiation or a target gas. CI Systems’ spectral gas imagers can reveal the answer in seconds, without any prior knowledge. In this case it was a R-134a gas. CI Systems’ spectral gas imagers are designed to identify target gas clouds. The explanation below describes the main difference between a FLIR camera and CI Systems’ gas imager.

Blue lasers with best-in-class BPP performances provide optimal weld quality for joining dissimilar metals, thanks to the ability to control the penetration depth and generate minimal defects while processing.
Femtosecond lasers are ideally suited for processing advanced medical devices that incorporate Nitinol. This is true for a range of Nitinol thicknesses, which can be processed with excellent throughput and quality.
Non-contact temperature measurement can be easily performed with Therompile detectors, which respond to the thermal energy emitted by any object within its field of view by producing a voltage that is proportional to the incident power.
