Performance
Uncooled thermal lens is widely use in thermal cameras, thermography for observation, industry, medical. There are mainly 3 type lenses.
Athermalized lens is main used for small size, fixed assemble application, such as security camera. Athermalized lens can keep imaging clear in different temperature, no need focus all the time. So it is popular for cameras which is not easy for human to focus by manual, such as camera in tower, mountain far from city...
Manual focus fixed lens is main used for handheld portable device, such as thermal scope, monocular, thermography. Manual focus can adjust imaging freely. So it can get better imaging quality by hand.
Motorized focus lens is main for big size lens. Normally it is hard to focus by hand. Motorized lens is also easy to remote control. Auto focus is available from core, or thirty part auto focus board. We provide fast auto focus time less than 2 seconds.
Connector to thermal core is standard parts if required. We can provide all kind connector according to requirement.
