Below are images to illustrate the difference in thermal lens size. The ATN ThOR 640 2.5X has a 50mm lens and the ATN ThOR 640 5X has a 100mm lens. All other factors including thermal cores are the same on these 2 units. Image Link for ThOR 640 2.5 50mm Image Link for ThOR 640 5x 100mm  |

All other factors including thermal cores are the same on these 2 units. All other factors are definitely NOT the same. The objective lens of the ThOR 640 5x obviously also has twice the focal length of the ThOR 640 2.5X. When both use the same microbolometer, double the magnification of the 5X results in 1/4 the area in the field of view, which requires four times the light gathering capability of the 2.5X. Doubling the objective lens diameter of the ThOR 640 2.5X provides exactly that. |

Using the links was cumbersome, is this what you are wanting to display? http://i932.photobucket.com/albums/ad162/hunttxhogs/50mmvs100mmcomparisonimage_zps05260f0d.jpg HTXH |
