Can thermal imaging lenses be used with ordinary cameras?

Thermal imaging lens can be equipped with ordinary cameras. The lens of an ordinary camera is usually made of optical glass, and its specialized function is, of course, to refract light, often called magnifying an object.

Optical glass is artificially synthesized. The main reason for the underexposure of infrared rays in ordinary cameras may be the sensor and lens. The attenuation of infrared light by ordinary lenses depends on the lens material, coating and the wavelength range of infrared light.

Advantages of ordinary cameras

First of all, ordinary cameras are mainly used for video chatting, photography and other activities, corresponding to daily life. Surveillance cameras are mainly used for a series of security activities such as security inspections, real-time monitoring, investigation and evidence collection. Secondly, surveillance cameras are controlled remotely and wirelessly.

Generally, the transmittance at the near-infrared end near visible light is still relatively high. In order to filter out stray light interference in bands other than visible light, cameras and photosensitive elements of cameras are usually equipped with visible light passing filters, so that infrared light is attenuated by the filter.

So to use a regular video camera, a camcorder that plays infrared, you need to remove the filter.
