FLIR is one of the most popular names of a company that is into the business with thermal imagers, although up until recently they were focused more on the professional side of things. Lately however the company is also seeing the big market potential that affordable consumer level thermal cameras in the form of accessories for mobile devices open up. The result is the FLIR ONE thermal imaging accessory designed especially for owners of Apple’s iPhone 5 and iPhone 5S smartphones. We are talking about thermal imaging accessory and not just for a thermal camera as the FLIR ONE comes with two cameras, one for visual light and one for thermography. FLIR has decided not to go using the built-in visual light camera into the iPhone 5/5S which is much better than the one they have included, but maybe their choice was based on design limitation or who knows. You should be aware of the fact that FLIR ONE comes in the form of a case for the iPhone 5/5S using the Apple Lightning interface and is not compatible with other iOS-based devices. While this design idea is fine if you own an iPhone 5 or 5S, but Apple has already released iPhone 6, so if you want to be able to continue using the FLIR ONE you would need to have a spare iPhone 5 or 5S even if you go and buy the new iPhone model.

We have already mentioned the fact that FLIR ONE comes with two cameras, one for visible light images and one thermal camera. FLIR uses the image data from both devices blending both images using MSX Technology and thus providing physical detail to the raw thermal reading. Normally thermal images do not reveal a lot of detail of the physical objects that you are checking as they contain thermal information, but when you take a visible light image as well and take the outlines of objects from it and blend that data with the thermal image the results are great. Even with lower resolution thermal image this method makes it possible to get a much better looking thermal images that are easier to read and understand, especially from people that are not too experienced with thermal imaging.

The FLIR ONE thermal imaging accessory is based on the small and affordable Lepton micro thermal imager. This small sensor is what makes possible to have a lower resolution FLIR thermal cameras available at very affordable prices. Even though the available 80×60 pixels thermal array from the Lepton sensor is not too much it is still quite useable, especially when you blend the thermal image with a visual one to provide more visual details to the user. It is interesting to note that when displaying real-time images or recording video, FLIR ONE employs an image enhancement that produces a 160×120 thermal image according to the manufacturer of the device.

FLIR ONE thermal imaging accessory specifications:
– Scene range temperature: 0°C to 100°C (32°F to 212°F)
– Weight: 3.9 ounces, 110 grams
– Dimensions: 140 x 61 x 22 mm (L x W x H)
– Battery capacity: 1400 mA/h (maximum thermal imager battery life is approximately four hours continuous use. FLIR ONE does not consume power from the iPhone battery, nor does it charge the iPhone battery)
– Core: FLIR Lepton thermal camera core (80×60 pixels)
– Visible camera: 640×480 VGA (used for FLIR MSX blending)
– Sensitivity: ability to detect temperature differences as small as 0.18°F (0.1°C)
– Charging method: micro USB and 1A wall charger (charges FLIR ONE only)
– iPhone compatibility: iPhone 5, iPhone 5S running iOS 7 or above

The FLIR ONE accessory for iPhone 5/5S is available at a price of $349.99 USD and we have already ordered one to use as a part fo our testing equipment, so soon you will be able to see actual thermal images as well as read our personal feedback from using the device. The only thing that we are not overly happy in the specifications of the device is the temperature range that it operates in, it would’ve been much better if it was a little bit wider than what it is. Other than that we hope to be satisfied with what FLIR ONE will provide us with in terms of resulting thermal images, though we are also looking at other alternatives as well as FLIR is already facing a bit of competition in the field of affordable consumer oriented thermal cameras. There are alternatives that are supposed to offer better specifications at least on paper, but FLIR has the advantage of years of expertise in thermal imaging.

The thermal imaging camera that we are using for testing with and the thermal images that you will see for the moment are from FLIR i7 – a proven and reliable and most of all quite affordable thermographic camera with decent specifications for our need and not so high budget. We have decided to go for the top model from the FLIR i-series of the i7, because it has the highest resolution thermal sensor from the range and we wanted to have the best resolution. Apart from the higher resolution, the bit wider FOV and the two additional measuring modes the FLIR i7 shares the same set of features and other specifications as the rest of the i-series.

The FLIR i3, i5 and i7 thermal cameras operate in the 7.5 – 13 µm range (7500 – 13000 nanometer range), have an image frequency of 9 Hz, use fixed focus lens and can detect objects within a temperature range of -20°C to +250°C, and the thermal sensitivity is 0.10°C with high accuracy of ±2°C or ±2%. The devices are equipped with a 2.8-inch color LCD display, have a MiniSD card slot for flash cards to store the thermal images on – the files saved are Standard JPEG with 14 bit measurement data included (radiometric JPEG format, containing all temperature data). The FLIR i-series of cameras are very easy to use, compact and lightweight, offer up to 5 hours of usage time with a single full charge and provide very good features for normal use packaged in an affordable for a thermal camera device. The price of a FLIR i3 camera currently goes between $1000-1200 USD, for a FLIR i5 you may have to pay $1500-1600 USD and a FLIR i7 will probably cost you around $2000 USD.

You cannot record thermal videos with the FLIR i7 or any of the two smaller models from that product range, you are able to view thermal imaging information live on the device’s display and also save it in radiometric JPEG files on the SD flash card. The produced JPEG files can be open with a normal JPEG photo viewer as a 240×240 pixel image (for the FLIR i7) containing the thermal image data, along with temperature information and a scale representing the thermal range. You can also open them with the FLIR Tools software that you get along with the thermal camera for a more detailed inspection and to output thermal images along with detailed reports for a more in-depth thermal analysis should you need to do so. Do note that while the thermal imaging sensor of the FLIR i7 camera is 140×140 pixels with some image processing the outputted thermal images can be saved with higher resolution and still loo quite good and detailed. However if you need higher resolution for a more detailed thermal inspection you should get a thermal camera with higher resolution sensor if your budget allows it as going up the resolution does lead to an increase in the price.
