    I would assume 8 microns would be ridiculously awesome. I heard 10 microns possibly a while back but nothing about the possibility of 8 microns.
    Would 8 microns with a 320 core look better than 12 or 17 microns with a 640 core??

    To my understanding the micron core size has nothing to do with the quality, or lack there of, the image. Just the size of the core itself. The smaller the micron number the smaller the overall unit can be and cheaper.

    While I'm not an optics expert, this is also my understanding. The resolution is based on the number of pixels in the sensor element. Physically smaller transistor/line width sizes mean smaller (ergo, cheaper) sensors but not better resolution. 320 pixels is still 320 pixels on your viewing screen.

    All things being equal, micron size will affect image quality, but all things are never equal between these companies. The smaller micron size will allow you to produce a comparable or better image from a smaller size of lens when dealing with the same number of pixels and level of native magnification.

    I don't know that smaller thermal sensors are necessarily cheaper, but since they can work well with smaller germanium lenses, the cost and weight of the scope is brought down. I don't know if it is still true today, but a few years ago, the lens itself was upwards of 50% of the cost of the entire scope, germanium lenses being that expensive to produce.

    Put another way... "Typically measured in micrometers, or “microns,” when you’re looking at a camera’s pixel pitch, keep in mind that lower numbers are better— the smaller the pixel pitch, the more image detail you’ll get in a smaller package."

    I believe you are correct and the way you stated it makes so much more sense than the way I stated it. Basically I was trying to say what you are saying I just did not do a very good job of wording it. Thank you for the information
