is the largest area that your imager can see at a set distance.
This table lists the horizontal FOV, vertical FOV and IFOV for lens.
(Instantaneous Field of View) is the smallest detail within the FOV that can be detected or seen at a set
distance, the unit is rad. The formula is this:
D:S ( = 1/ IFOV ) is the calculated spot size based on the pixel size of the Thermal
Imager detector array and lens focal length.
Example: If Thermal Imager uses 9mm lens, because the Pixel Size of detector is 25um. Horizontal FOV is
19°, Vertical FOV is 25°, the IFOV is
25um/9mm = 2.78mrad;
D:S theoretical ( = 1/ IFOV theoretical) = 359:1
D:Smeasure ( = 1/ IFOV measure) is the spot size needed to provide an accurate temperature measure.
Typically, D:Smeasure is 2 to 3 times smaller than D:S theoretical, which means the temperature measurement
area of the target need to be 2 to 3 times larger than that determined by the calculated theoretical D:S.
IFOV theoretical represents the smallest objects that the thermal imager can detect or see. IFOV measure
represents the smallest object form which an accurate temperature can be measured by the thermal imager.

To adjust focus, clockwise or Anti-clockwise rotates the IR Lens. When target comes into focus, it shows
a sharper image. When the target moves out of focus, the thermal image becomes blurry.
Correct focus is important in all imaging applications. Correct focus makes sure that the infrared energy
is correctly directed onto the pixels of the detector. Without the correct focus, the thermal image can be blurry
and the radiometric data will be inaccurate. Out-of-focus infrared images are frequently unusable or of little
value.
The thermal image of the Thermal Imager becomes blurry, when the Thermal Imager no correcting after
some minutes or the Thermal Imager changes target. To get fine thermal image, the Thermal Imager need
to correct.
The Thermal Imager has two mode for correcting, Manual and Auto Mode. In Manual Mode, push the
Power button, the Thermal Imager will correct. In Auto Mode, the Thermal Imager can correct automatically
while The thermal image of the Thermal Imager becomes blurry .

6.10-Temperature Measurement
6.11-Emissivity Adjustment
All objects radiate infrared energy. The quantity of energy radiated is base on the actual surface temperature
and the surface emissivity of the object. The Thermal Imager senses the infrared energy from the surface
of the object and uses this data to calculate an estimated temperature value. Many common objects and
materials such as painted metal, wood, water, skin, and cloth are very good at radiating energy and it is easy
to get relatively accurate measurements. For surfaces that are good at radiating energy (high emissivity),
the emissivity factor is >=0.90. This simplification does not work on shiny surfaces or unpainted metals
as they have an emissivity of <0.6. These materials are not good at radiating energy and are classified as
low emissivity. To more accurately measure materials with a low emissivity, an emissivity correction is
necessary. Adjustment to the emissivity setting will usually allow the Thermal Imager to calculate a more
accurate estimate of the actual temperature. More information please see Emissivity Adjustment to get the
most accurate temperature measurements.
The correct emissivity value is important to make the most accurate temperature measurement. Emissivity
of a surface can have a large effect on the apparent temperatures that the Thermal Imager observes.
Understanding the emissivity of the surface, but may not always, allow you to obtain more accurate temperature
measurements.
Surfaces with an emissivity of <0.60 make reliable and consistent determination of actual temperature
problematic. The lower the emissivity, the more potential error is associated with the Imager’s temperature
measurement calculations. This is also true even when adjustments to the emissivity and reflected background
adjustments are performed properly.
Emissivity is set directly as a value or from a list of emissivity values for some common materials. The
global emissivity displays in LCD Screen as E=x.xx.
The following table gives typical emissivity of important materials.

6.12-Reflected Temperature
6.13-Thermal Imager Reporter Software
Using the offset factor, the reflection is calculated out due to the low emissivity and the accuracy of the
temperature measurement with infrared instruments is improved. In most cases, the reflected temperature
is identical to the ambient air temperature. Only when objects with strong emissions with much higher
temperature are in the proximity of the object being measured should be determined and used. The reflected
temperature has only little effect on objects with high emissivity. The reflected temperature can be set individually.
Follow these steps to get the right value for the reflected temperature.
Set the emissivity to 1.0
Adjust the optical lens to near focus
Looking in the opposite direction away from the object, take a measurement and freeze the image
Determine the average value of the image and use that value for your input of reflected temperature.
Thermal Imager Reporter software is supplied with the Thermal Imager. This Software is intended for
Thermal Imager and contains feature to analyze images, organize data and information, and make professional
reports. Thermal Imager Reporter software allows audio annotations and commentary to be reviewed on a PC.
