Buy Low Illumination IR Camera

May 12, 2017

As an important part of IR camera, the function is to focus the CCD light on the infrared camera, so that the scenery is imaged on CCD. The amount of light it can ingest directly determines the clarity of CCD imaging. Measure the amount of light in the lens intake, called the amount of light, the lens into the amount of light with the F value (Aperture). F Value =f (focal distance)/d (the effective caliber of the lens), it is inversely proportional to the caliber, and the focus distance is in proportion. In the same focal length, the larger the aperture of the lens, the smaller the F value, the greater the amount of light into the lens. The common lens f value is 1.2, 1.4, there is also F1.0 lens. Therefore, in order to make the IR camera get the ideal low illumination effect, it is necessary to configure a lens that fits or configures a smaller F-value.
