Infrared cameras are used for non-contact temperature measurement and for the detection of twodimensional temperature distributions with high thermal resolution on stationary and moving measurement objects. We have introduced the longtime experience in the field of thermography into our infrared camera series.
The devices are durable, robust and suitable for industrial continuous operation. Our infrared cameras are used in process control and monitoring, quality control, early fire detection as well as for measurements in research and development.

UV cameras are a style of video camera that have been optimized for capturing light from the ultraviolet spectrum. This is accomplished by using a UV-pass filter, which will only allow light below the visible spectrum (wavelengths less than 400 nm). UV-A light, also called near ultraviolet, has a wavelength between 320—400 nm and is most relevant to UV photography. UV wavelengths let surfaces appear in greater clarity, and often depict features which are otherwise not apparent.
UV cameras operate in a fashion similar to CCD video cameras, with the main difference being that they record UV-A light. Regular CCD sensors are capable of recording UV light. UV-B light is absorbed by most lens materials, and UV-C light is absorbed by oxygen, making them mostly unimportant. While some video cameras may utilize a UV-cut filter to remove UV light from their recording, these types of cameras employ a UV-pass filter, isolating UV from other light spectrums. These filters are always made of glass, but also tend to allows large amounts of infrared light. Special filters and techniques (e.g. lighting, hot mirror filter) can be used to limit the IR contamination of UV images.
UV recording takes place via either reflected UV photography, or UV fluorescence photography. Reflected UV photography involves the direct illumination of subjects by UV sources, such as the sun. UV fluorescence technology involves the removal of visible light by filtering the light source. This ‘exciter’ filter should be used in conjunction with another UV-pass camera filter, and recording must be done in very dark environment.
The camera lens is one of the most critical factors in capturing UV light. To create a better illuminated subject by also capturing UV-B light, a special and expensive type of camera lens made of quartz or quartz-fluoride allows for the transmission of UV light in the 180—200 nm wavelengths. A less-expensive, but viable option would be to use older (pre-WWII), uncoated or single-coated camera lenses. These thinner lenses without optical polymers can satisfactorily transmit some low-wave UV light.

Thermal night vision cameras is a technology that has been used by the military and emergency services for many years, whether it’s the police detecting criminals or firefighters seeing through blinding smoke. However, the popularity of thermal night vision cameras is continually growing, becoming more accessible and is now frequently being used for everyday activities. This includes being implemented into a number of new cars.
So how is thermal night vision cameras useful in a car? It is essentially a night vision system that displays an image of the road ahead by picking up infra-red radiation that is invisible to the human eye. The image is displayed in black and white on a screen and hot items, whether it is a living object or a car exhaust will glow white, while colder items such as the night sky will appear black.
Now you might be thinking “Why would I need a thermal night vision cameras in my car?” And perhaps it has crossed your mind that it is just another unnecessary extra cost you don’t need when choosing your next car. However, having thermal imaging in your car does have its benefits, especially in terms of safety.
Why is thermal night vision cameras important?
Did you know that, in the US 55% of all fatal accidents occur at night despite only 28% of driving being done at night? Similarly in Germany, half of fatal car accidents happen at night, although only a quarter of all driving is done at night. This means that the risk of driving at night is twice as high as during the day.
Having a thermal imaging system in a car can significantly help to increase drivers’ and passengers’ safety and decrease the number of fatal and serious accidents. The thermal night vision cameras allows drivers to detect animals or pedestrians at a range of roughly 300m, which is far greater than you can see with just the car’s headlights.
This is not only improving the safety of drivers and passengers but also any pedestrians that are walking along the road at night time. The technology also gives the driver more time to react to any sharp corners or obstacles in the road because the device clearly displays the road ahead.

The aim of this study was to assess the temperature changes of selected body surfaces (the arm and forearm) as a response to 90-minute physical exercise as well as to analyze the impact of physiological and morphological factors on the dynamics of temperature change. Methods. A study group that consisted of 12 professional volleyball players was subjected to endurance training which lasted 90 minutes. Numerous physiological and morphological factors were measured, with mean temperatures registered from the body surface of the upper extremities before, immediately after, and ten min after physical effort by a thermal imaging core at room temperature. Results. After physical exercise, a fall in skin temperature resulting from prolonged sweating during the dynamic exercise tests was observed. The temperature changes in volleyball players, recorded in a series of tests, were found to be larger on the front surfaces of their upper extremities when compared to the rear. In addition, statistically significant positive correlation between maximum oxygen uptake (VO2max) and %HRmax, calculated with the decrease in skin temperatures, was found. Conclusions. The strong and statistically significant influence of maximum oxygen uptake on the drop in surface temperature of the upper extremities (arm and forearm) immediately after the exercise indicates that thermography can be used as an additional, non-invasive method that provides information on a player’s fitness level in comparison to other athletes.

In the equestrian sports thermal imaging cameras are often used to determine and locate injuries in performance horses, but a study at the Veterinary Teaching Hospital of the University of Helsinki shows that thermal imaging cameras are a good tool to find health issues in small animals as well. “The research is not yet complete, but my initial findings are very positive”, explains veterinarian and researcher Mari Vainionpää.
“Unlike humans animals cannot tell the doctor what they are feeling. This can make it very challenging for veterinarians to find clinical problems in animals.” In thermal imaging Vainionpää has found an exciting solution. “Thermal imaging cameras really are a great tool to find out whether an animal is in pain, for instance.”
But thermal cameras can do much more. “All organic activity generates heat”, continues Vainionpää. “If there are changes in the organic activity there are also changes in the amounts of heat that are emitted. These deviations in the heat pattern can be detected with a thermal imaging camera. In my experience a thermal imaging cameras can be used to reveal inflammations, bruises, tendon or muscle related injuries, superficial tumors, nerve damage, blood circulation issues.”
Infrared lenses radiation is characterized by wavelengths ranging from 0.750 -1000μm (750 – 1000000nm). Due to limitations on detector range, Infrared lenses radiation is often divided into three smaller regions: 0.750 – 3μm, 3 – 30μm, and 30 – 1000μm – defined as near-infrared (NIR), mid-wave infrared (MWIR), and far-infrared (FIR).
Infrared lenses products are used extensively in a variety of applications ranging from the detection of IR signals in thermal imaging to element identification in IR spectroscopy. As the need for IR applications grows and technology advances, manufacturers have begun to utilize IR materials in the design of plano-optics (i.e. windows, mirrors, polarizers, beamsplitters, prisms), spherical lenses (i.e. plano-concave/convex, double-concave/convex, meniscus), aspheric lenses (parabolic, hyperbolic, hybrid), achromatic lenses, and assemblies (i.e. imaging lenses, beam expanders, eyepieces, objectives).
These Infrared lenses materials, or substrates, vary in their physical characteristics. As a result, knowing the benefits of each allows one to select the correct material for any Infrared lenses application.
