Trijicon specialized in infrared aiming systems for firearms. The company provides solutions for amateur enthusiasts, such as hunters, and professional-level firearms, like the United States Marine Corps and law enforcement departments. 

Thermal Sensor Resolution Ranges

Below we outline the different levels of thermal resolution available.

Low

This range includes detectors spanning from 160x120 up to 384x288. These cameras can provide a generalized idea of heat distribution in their images but lack clarity. On the other hand, they are generally affordable for home use.

Medium

Mid-range includes products with detectors measuring around 640x480, which was considered high until recently. These are good-quality cameras that provide reasonable thermal resolution but come with a higher price tag. 

High

At the higher end of the scale, you'll find thermal imaging cameras with detectors offering 1024x768. This means 786,432 pixels compared to the 19,600 provided by a 160x120 low-range detector. The image quality is much sharper at this level, and you can use it for more sophisticated thermal imaging applications.

At the highest end of the range, you'll find cameras with detectors that can achieve 1920x1200, which is equal to Full HD and offers mind-blowing clarity.

Who Makes the Highest Resolution Thermal Sensor Currently?

With a Full HD thermal resolution of 1920x1200, the Vayu HD camera from Sierra-Olympic Technologies is the highest-resolution LWIR thermal imaging camera available today. It benefits from an uncooled VOx microbolometer array and weighs only 450g with a 25mm lens, rising to 520g with a 50mm lens.

Where to Buy the Best Infrared Camera

There are many superb thermal cameras on the market today, many at prices that even amateur photographers can afford. However, the Vayu HD camera truly stands at the top of the range.

With its lightweight body and stunning resolution, it's an awe-inspiring piece of equipment. This advancement certainly establishes Sierra-Olympic Technologies as a growing name in the infrared imaging market.
