Infrared laser

Military infrared laser

So how does an infrared laser work? To understand this, you must first know about the light spectrum. A light wave has amounts of energy that is related to its wavelength, which in turn determines how visible it is to the eye. The visible light spectrum has all the colors that the human eye can see, of which in the highest level is violet and the lowest is red. Next to the visible light spectrum, laid out is the Infrared Spectrum. It has three categories >>>

Infrared LED

Infrared LED

An infrared light-emitting diode (infrared LED) is a small device used primarily on electronics which emits light that is on a different wavelength, lower than the visible light. A regular LED is commonly referred to as a small indicator light, which functions as a semi-conductor type of diode. Infrared LED also somehow works in this manner, as well as minimal data transfer between electronic devices (e.g., remote control devices), acts as illuminators for night vision equipments, and several more purposes. From the edge of red >>>

Heat Vision Goggles – New Generation of Thermal Imagery

View trough thermal viewer

Isn’t it fun to see something so easily while in the dark? Nowadays, thermal imaging goggles are great for having fun while doing your hobbies, search and rescue missions at rugged conditions or and even finding lost pet or your hunting trophy in a pitch black environment. The main purpose of heat vision or thermal imagery devices is to see something in the dark through focusing on the heat or temperature radiated by objects and creatures. The heat vision goggles or other thermal imagery device >>>

IR Illuminators – Invisibe Infrared Light Flashlights

PEO PEQ 15 Infrared Laser Illuminator

An infrared light, commonly abbreviated as IR, is an electromagnetic radiation emitted in a longer wavelength than the visible light, with an approximated frequency range of 1 to 400 THz which also covers the range of thermal radiation of objects with temperature close to 67.9 to 70.7˚F or normal room temperature. The International Commission on Illumination (CIE) suggested a categorization of infrared radiation into the following bands: a) Near-Infrared, NIR / IR-A (700 nm to 1,400 nm or 0.7 μm to 1.4 μm; 215 THz >>>

Infrared Security Camera – Excellent Protection through Invisible Light

Infrared Security Camera

Protection is very important these days as anytime, anywhere, and somehow criminals, burglars, and other dangers could get inside your home and cause havoc and chaos in your family unlike anything you’ve ever known. Well that could be a little too exaggerated, but it is possible, though by a very small chance would you let that small chance put your family’s safety at risk? Through the use of infrared security cameras, you can take advantage of the dark and prepare for coming dangers even before >>>

Thermal Cameras – Track the Danger Through Heat!

Thermographic Camera (photy by Etan J. Tal)

One of the most innovative inventions for detection and surveillance is the Thermal Camera. There is a wide range of security cameras that you can choose from but most of these works only when significant to a low level of light is present. The Thermal Camera is the only one that can function and track movement and images in total darkness. It tracks the heat due to radioactivity and atomic activities of the objects and is currently used to for a number of things from >>>

Night Vision Riflescopes and Weapon Sights

Military Tactical Gear

Night vision is basically an enhanced ability to see one’s surroundings with a minimal presence of light. It is a combination of an adequate amount of spectral range and intensity range. The former refers to a sensing technique which perceives radiation invisible to the human eye or is not in range with the “visible” light spectrum for humans. Compared to nocturnal and several other animals, humans have poor night vision because of a certain layer of tissue in his eyes called the “tapetum lucidum”. It >>>

Thermal imaging scopes and viewers

Thermal Scope View (by Arno / Coen)

The increase in radiation emission is directly proportional to the increase in temperature of an object, hence, one what one can see through thermal imaging cameras are varying levels of temperature of images. Warm objects tend to become highlighted from dark colored objects which are supposed to be cool ones such as the environment. There is a sort of luminance or glow against a cool and dark background. This technology has been largely utilized by firefighters to locate the central part of the fire, to >>>

Thermal Imaging Basics

Infrared imaging (picture by Passivhaus Institut)

According to the Law of Black Body Radiation, anything that has a temperature above zero emits an infrared radiation which produces images called thermograms. Any image of the radiation emitted in the infrared range of around 9,000 to 14,000 nanometers in contrast to common cameras with a range of 450 to 750 nanometer (according to the electromagnetic spectrum) is distinguishable and can be perceived through thermal imaging cameras. Therefore, through thermal videography, one’s sight is extended and heightened in the sense that he is able >>>

Infrared Scope – Insights to the First Night Vision Devices

PVS-14 Military Night Vision

Night Vision goggles, scopes, cameras, and other equipments are the brain child of the very first person to ever create Infrared Night Vision Devices—Dr. Vladimir K. Zworklyn. He was task to develop infrared devices for use by the masses and not intended to be used by the military. After its discovery, Infrared technology has migrated from providing commercial uses to civilians to war purposes by the military. The company that started developing these first military tools was named AEG, or Allgemeine Elektricitats-Gesellaschaft or literally meaning >>>
