Broadband Thermal Infrared Cameras
Broadband Midwave (MWIR) infrared cameras capture light in the 1.5 μm – 5 μm (1,500 nm to 5,000 nm) electromagnetic spectrum and Broadband uncooled thermal cameras in the 3 μm – 14 μm (3,000 nm to 14,000 nm) spectral band. They are designed and manufactured with specialized lens and detector coatings, as well as unique electronics to give the user the ability to visualize across various spectral bands.
These cameras are produced for a niche group of users/consumers that need a detailed image that is unable to be produced with other types of infrared cameras. Producing a Broadband Infrared Camera (IR) does cost more, however, the image that comes from such a camera is unparalleled in details and valuable information.
Very few companies manufacture a broadband camera that sees from Midwave through the Longwave length (3 μm – 14 μm), such as our 8640 Broadband 3 μm to 14 μm | Thermal Infrared Camera.
There are many applications that would benefit from the unique properties that Broadband Thermal Infrared Cameras can offer. In the industry field, companies that image furnace tubes, such as refineries, chemical plants and utilities, can place a 3.9 μm flame filter in front of the sensor and see through the flame or measure boiler or furnace tube temperatures all with a low cost $14,995 Uncooled Broadband Camera versus a $85,000 Cooled 3 μm – 5 μm MWIR Camera.
Since neither CO or CO2 gas emits energy at 3.9 μm, the flame on a stove or furnace is invisible to these Broadband cameras. This allows a gas stove manufacturer to measure the steel griddle temperature with no interference from the flame.
Your typical IR camera cannot give you the temperature measurement of a thin plastic sheet or of plastic, nylon or rubber balloons. However, since plastic emits at approximately 4.3 μm, you can use a Broadband IR Camera to measure its surface temperature. Until the last few years, this was only possible with a cooled $80,000 MWIR Camera.
These Broadband Infrared Cameras are also valuable to scientists. NASA could easily use one to image the Sun, finding different deviations in the Sun’s thermal energy. These cameras could also be used to make an imaging spectrometer to identify different metals or plants on the ground or the soil on Venus or Mars.
