Different Wave Length Camera

We savgood is committed to deal with different range of block camera module, including day (visible) camera, LWIR (thermal) camera now, and SWIR camera in the near future.

Day camera: Visible light

Near infrared camera: NIR——near infrared (band)

Short-wave infrared camera: SWIR——short-wave (length) infrared (band)

Medium-wave infrared camera: MWIR ——medium-wave (length) infrared (band)

Long-wave infrared camera: LWIR——long-wave (length) infrared (band)


We have many EO/IR cameras. Visible light cameras support optical fog penetration. The wavelength of optical fog penetration is 750-1100nm, which is equivalent to NIR effect, similar to SWIR effect.

In day mode, the sensor can sense all light, including visible light, infrared, and ultraviolet. In day mode, the function of the filter is to remove light other than visible light and make the image appear in color. In black and white mode, the LED light emits infrared rays, and the infrared rays reflect back to the sensor to image.

Normally, IR camera refers more to the monitoring aspect. It corresponds to the near-infrared that is close to visible light. The equipment used is basically the same as that of visible light, but the coating of the lens is different. At the same time, the infrared filter on the surface of the CCD/CMOS sensor is removed. While Infrared thermal imaging is medium and long-wave infrared (far-infrared) with a wavelength of 8-14 microns. The lens is made of germanium and other materials. The sensor is not an ordinary CCD or CMOS. The image obtained is actually a different color that is considered to be given to different temperatures.
