Is a 640 or 384 sensor better in a thermal scope? with ben from huntthenight.com.au
Every wondered what the real difference between a 640 and 384 sensor is? In base magnification you might be surprised by the answer!

I came in late. what has the drawing of a saw horse in an open garage for to do with thermals?.. great explanation. I will admit to not understanding the sensor difference and just thought bigger meant better. Now I get it. Thanks
Great video Ben. So how does lens size change the view with the same type of sensor? ie 30mm vs 42mm

Lens size will have an effect on base magnification, eg a 50mm 640 will be 2x, 75mm 3x and 100mm 4x. This will effect other things like field of view, NETD, and also how the unit will work in inclement weather. Field of view will decrease as the lens size increases as the base magnification increases. One other point I didn't make in the video is that detection and identification ranges for scopes that are like for like are identical as well.
What if the pixel distance is different ie 12um to 17um is that also a consideration ??

It’s the same thing Doug, if it’s like for like the pixel density is the same.
