Polarimetric Cooled Infrared Detectors
Quantum well infrared detectors are by design inherently suited for polarization sensitive imaging at the pixel level, within the need of filters. IRnova´s QWIP detectors offer both, highly sensitive infrared imagery and polarization sensing within...
Block Engineering's Tunable Mid-IR Quantum Cascade Lasers
Block Engineering's widely tunable mid-infrared Quantum Cascade Lasers are designed for use by researchers and manufacturers. Our next generation design features a six-fold increase in laser power, orders of magnitude better thermal and temporal...
Noise Mitigation Strategies for Infrared Detection
When it comes to infrared measurements, a lock-in amplifier paired with a pulsed light source is an essential tool to increase the signal-to-noise ratio (SNR) for low light applications. This tech note highlights the advantages of using a lock-in...
Bridging the Terahertz Gap with Simulation Software
Technologies that leverage terahertz radiation have potential to be used in areas such as imaging, security, nondestructive testing, and quality assurance. However, these exciting technological possibilities are largely underused and untapped due to...
3 Questions to Ask Before Buying Infrared Interferometry
Important considerations in obtaining infrared optical metrology, for measuring transmitted wavefront error, optical quality, and surface quality. The paper asks questions to help guide the reader in determining need, finding workarounds (if any),...
Diamonds are Forever: Using NIR to Find the Fakes
Cubic zirconia is easy and inexpensive to make and the diamond industry has long considered it an existential threat. Consider a diamond crusted band, what if some of those diamonds are actually cubic zirconia? Most people would never be able to...

– High Dynamic Range (HDR): How it works and what the benefits are
The ImageIR infrared camera series from InfraTec is available with a new function: HDR. The High Dynamic Range (HDR) function enables the analysis of objects with large temperature gradients in a thermal image that shows a very high dynamic range....
Can an Integrated MWIR Camera and Continuous Zoom Lens Save Time and Money?
Midwave infrared (MWIR) cameras with continuous zoom optics provide powerful thermal imaging over a range of distances, but integrating the lens and camera pose unique challenges. This paper explores these obstacles and illustrates how FLIR, as a...
SWIR Shining New Light on New Farming Techniques
The technology to drive precision farming is changing, the evolution includes the move to short-wave infrared (SWIR) imaging. While the spectral content of targets in SWIR is different, the images produced are more visual in their characteristics...
Using Lighting To Optimize Camera Performance
A rule of thumb in imaging is that there can never be too much light. A common problem is finding enough light to clearly image a subject. Utilizing light sources in an efficient and deliberate manner can address this problem by reducing the amount...
When to Choose HOT MWIR Over Uncooled LWIR
Cooled midwave infrared (MWIR) cameras have long held a tactical advantage over uncooled longwave infrared (LWIR) cameras in many airborne and ground-based missions. But while cooled MWIR cameras are highly sensitive, they are also larger, heavier,...
Ordering Options: What Does Your Camera Need?
This paper covers how to best optimize a camera order to improve camera performance. The topics in this paper include: camera ordering options, removing cover glass, removing all the glass within the camera (including the optical window and cover...
How Infrared Cameras Capture Beyond the Invisible
Infrared cameras, also known as thermographic cameras, differ from cameras that capture images within the visible spectrum. In fact, infrared cameras can only capture images of objects that omit radiation in the infrared region, which can be well...
Optical Components for SWIR Imaging
Precision Glass & Optics discusses the challenges of designing optical coatings for shortwave infrared (SWIR) imaging. Also discussed are the many advantages that SWIR imaging devices provide.
See How Forensic Investigators Research Cases Using FLIR Thermal Cameras
Researchers have been looking for an alternative method of detecting the presence of dilute concentrations of blood on fabric. They have found a solution in thermal imaging with FLIR thermal imaging cameras. While blood is not visible on its own in...
10 Steps to Choosing the Right Optical Coating
There are some critical steps you should consider when selecting an optical thin-film coating to maximize your optical systems’ performance. Small changes in requirements can often have a significant impact when evaluating performance and cost....
Infrared Camera Accuracy and Uncertainty in Plain Language
How accurate are thermal imaging cameras, and how are they calibrated? Understanding infrared camera accuracy and sensitivity can help clarify the value of well-calibrated thermal imaging cameras. In this paper, we use layman’s terms to explain how...

DRS Technologies’ Patented Sensor Technology Revealed
Learn the truth about what’s behind DRS Technologies’ competitive advantage over thermal sensor manufacturers – the patented Advanced-Absorber Microbolometer Superstructure, providing better performance through superior image quality and enhanced...
Heat Treating with High Power Diode Lasers
CO2 lasers have been used to case harden metal products for decades, but their low reliability and electical conversion efficiency makes them less than ideal for such heat treating tasks. High-powered laser diode lasers overcome the disadvantages of...
Cladding with High Power Diode Lasers
This article provides an introduction to high-power diode laser technology and its use in cladding. In particular, it compares the capabilities and characteristics of diode lasers with traditional cladding methods as well as alternative laser...
An Introduction to Diode Lasers for Materials Processing
Low-power diode lasers are a well established technology, used extensively in products such as DVD players, computer optical drives, fiber-optic telecommunications and even laser pointers. While these commonly encountered low power diode lasers...
