Best Thermal Monocular Buying Guide
These are the characteristics that one should consider when buying a thermal monocular for under $1000
Sensor resolution
A thermal sensor is used to detect the thermal energy and convert it into an electrical signal that is used to display a thermogram image to the user. These sensors are available in different resolutions, examples include
- 160 x 120 pixels
- 384 x 288 pixels
- 640 x 480 pixels
The microbolometer’s sensitivity, detection range, and ability to produce sharper images increase with the number of pixels. Although these cost-effective choices lack a powerful high-end sensor, they do include mid-range sensors that work well over closer ranges.
Display resolution
It can be confusing comparing this to the sensor’s resolution, it’s important however that you consider looking at it, because it denotes the total vertical and horizontal pixels on the screen that displays the thermogram.
Like the sensor resolution, however, the higher the resolution the better the image will appear to the user. Examples of screen resolutions are 4k FHD and HD.
- 4K-3840 x 2160 pixel
- FHD-1920 x 1080 pixels
- HD-1080 x 720 pixels
Magnification
The level of magnification, which is denoted by ‘X,’ shows how much the target image is enlarged relative to the original one displayed without magnification. 3x magnification, for instance, means that the image is 3 times the original.
Magnification is important for spotting distant targets since their faint heat signatures often go undetected at such a distance. Because of this, monoculars frequently come with magnifications for example 2.5x and 4x, with the more powerful ones having a higher magnification.
Refresh rate
This is shown in Hz and refers to the many times that an image is regenerated on the screen per second. A higher refresh rate results in a sharper image, and less lag, especially when one is tracking a moving target and moving the monocular in the process.
Battery life
The thermal sensor and the display are both powered by a battery, therefore the more potent it is the longer the thermal monocular, will work. A good thermal monocular should give you a decent life, of more than a few hours to make sure that you have the best of your time outdoors.
Durability
Even for the ones that cost under $1000, a thermal monocular is an expensive piece of equipment, that may be a real nuisance to repair or replace.
Although damage is occasionally unavoidable, a decent monocular should have some robust qualities like sturdy housing and waterproofing, ensuring that it can handle some of the severity that comes with the outdoors.
Weight
Until you have to move for hours on end with a heavy monocular, this may not seem like a quality of actual relevance.
Although the ideal weight varies depending on the user, it’s good for a monocular to be light enough to be comfortable to use especially for extended periods of time without feeling exhausted.
Color palettes
These are the contrasting colors on the thermogram, that represent objects of different temperatures or thermal energy. If you have a certain preference for the colors that are used on a monogram, it’s a good thing that some thermal monoculars give you the option of different color palettes.
Thermal Monocular FAQs
How do you use a thermal monocular?
A thermal monocular has various uses which include;
- Security Surveillance-When its extremely dark, the thermal monocular can be used to carry out a surveillance, they provide a covert way to monitor your premise without being noticed.
- Hunting-A thermal monocular is a common device used to identify animals that are hidden in thickets. A thermal monocular is also useful to identify wounded targets because the blood released gives off a heat signature.
- Search and rescue-Incase of a disaster a monocular is a helpful device to identify victims through the obstacles.
Can a thermal monocular be used in daylight?
Yes! Many people prefer thermal imaging because it provides the user with the flexibility to use it both during the day and at night. Thermal imaging generates a thermogram image by measuring the temperature difference between a target object and its surroundings. Every object, including ice, emits thermal energy, and the temperature difference between two objects can be as small as 0.001 degree Celsius.
Conversely, night vision makes use of an intensifier tube to boost the ambient light surrounding a target. This means that the bright light present in daylight would be amplified, potentially damaging the intensifier tube or the user’s eye.
