: Measures the sensor's ability to detect tiny temperature differences. A lower number is better; high-end optics like those from Pulsar often feature sub-25mK or even sub-18mK ratings for better detail in fog or rain.
: This is the most critical factor for target identification. Entry-level sensors are typically , mid-range units use , and high-end professional models feature buy thermal vision
When reviewing thermal optics, focus on these technical parameters which directly impact performance: : Measures the sensor's ability to detect tiny
: For tracking moving targets without blur, look for at least 50 Hz . mid-range units use
