                     WHAT ARE THE QUALITIES OF A GREAT THERMAL 
MONOCULAR
Thermal monoculars are quickly 
turning out to be the most 
acknowledged night optic on the 
market. In the last few years the 
thermal monocular has very 
closely followed the mobile in 
regards of development.
The devices have been developed 
with improved specifications & 
more useful features. The design 
has become more durable and 
compact and the overall quality 
has increased significantly. The 
main area in which the 2 
technologies vary is cost. While 
mobile phone technology has 
climbed in terms of cost thermal 
imaging has dropped, making 
thermal imaging gadgets 
affordable personal devices.
So, what are the qualliitiies of a great thermall 
monocullar?
Microbolometer:
The microbolometer is a sensor 
found inside the thermal monocular 
which identifies temperature 
patterns. The resolution of 
microbolometer is measured in 
pixels. Like a television the higher 
the pixel amount is, the greater the

In general, the refresh rate of a 
thermal monocular is the rare at 
which the picture is refreshed on 
screen. This rate is measured in 
“Hertz” with typical refresh rates 
about 9Hz, 30Hz, 50Hz and 60Hz. 
The higher the “Hz”, the more 
frequently the picture is refreshed.
If you’re in search of a recreational 
camera to explore the outdoors, 
then 9HZ will be sufficient. 
However, if refresh rate is more 
important to use as a user, we 
suggest 30Hz or higher. 60Hz is 
highly recommended for activities

The lens of a thermal monocular 
plays an important tile in finding out 
the utmost detection distance of a 
thermal monocular unit. Detection 
distance can differ between ninety 
meters to more than 1.5 kilometers. 
Lens sizes can differ from 9mm to 
100mm.  The bigger the size of the 
lens the better!
While a larger lens may amplify the 
detection distance of the thermal 
monocular, it also narrows the FOV 
(Field of View). For instance a 38mm 
lens will offer you a Field of View of 
19.5’ x 14.7’ whereas a 50mm lens 
cuts FOV down to 7.5’ x 5.6’. So, it’s 
critical to buy a monocular that not 
just offers you sufficient detection 
distance, but also matches your 
requirements in regards of FOV.
Also, it’s critical to take into account 
the image quality vs. distance 
provided by lens sizes & sensor 
resolution.
