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 qualities of a great thermal monocular?

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 level of detail you’ll see.

Refresh Rate:

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 such as professional hunting.

Size of the Lens:

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.
