Judge More Than Resolution Alone
Sensor resolution, NETD or thermal sensitivity, pixel pitch, refresh rate and image processing work together to determine the usable thermal image.
Texas Guns Thermal Optics
Explore thermal weapon sights, clip-on optics and handheld monoculars for hunting, scouting, observation and property use. Texas Guns helps you compare sensor resolution, thermal sensitivity, pixel pitch, refresh rate, lens size, native magnification, field of view and mounting requirements.
Sensor resolution, NETD or thermal sensitivity, pixel pitch, refresh rate and image processing work together to determine the usable thermal image.
Lens size and native magnification affect identification detail, viewing width and handling. Digital zoom enlarges the image but cannot add native sensor detail.
Each format has different requirements for recoil rating, zero retention, mount height, eye relief, battery life, controls and overall weight.
Thermal devices detect temperature differences; environmental conditions can affect image contrast and useful range. Detection is not the same as positive identification. Confirm device, mount and firearm compatibility, and verify current hunting regulations for the species, season and location before use.
