Why is the image quality worse at low temperatures compared to positive temperatures?
At positive temperatures, objects and backgrounds warm up at different rates, resulting in better temperature contrast for thermal imaging. However, at low temperatures, objects and the environment tend to cool to similar temperatures, reducing contrast and leading to less detailed images.
Thermal Vision Common Questions
Does a Pulsar thermal imager emit radiation? Is it dangerous?
Can I use a thermal imager to see through glass?
Can bright sunlight damage a Pulsar thermal imager?
What is the service life of thermal devices?
Why does the unit drain batteries when it’s switched off?
Can I use Pulsar thermal riflescopes on heavy-caliber rifles?
What is zoom zeroing used for?Zoom zeroing enhances the precision of riflescope zeroing by allowing adjustments while the scope is zoomed in. For instance, at 2x magnification, the click value becomes twice as small (e.g., 1.6x2=3.2). Similarly, at 4x magnification, the click value reduces to one-fourth. This allows for finer adjustments to the point of impact, resulting in a more accurately zeroed riflescope. Click values for each scope are detailed in the reticle catalog or user manual.
Why is there no sound when playing videos on iOS devices, even though the microphone is on?
Are the batteries in my Pulsar device charged, or do I need to charge them before first use?
Why does the device body get hot during operation?
Why does a semi-circular flare appear at the bottom of my thermal imaging screen after a shot?
Do I need permission to travel with a Pulsar thermal imager to other countries?
