Although the infrared lens has only just emerged, the application surface has not yet been popularized. However, with the general trend of security HD, infrared cameras will certainly wind up.
Infrared (IR) lens technology At present, infrared cameras on the Chinese market mainly use infrared filters to achieve day and night conversion, that is, open the filter during the day to block infrared light from entering the CCD, so that the CCD can only sense visible light; night vision Under conditions with poor lighting conditions, the filter stops working and no longer blocks infrared rays from entering the CCD. Infrared rays enter the lens for imaging after being reflected by the object.
However, in practice, it is often the case that the daytime picture is clear and the picture is blurred under infrared light conditions. This is because the wavelengths of visible light and infrared light (IR light) are not the same and the wavelengths are different, which can result in different focal planes of the image, resulting in virtual focus and blurring of the screen.
The IR lens adopts the latest optical design methods, special optical glass materials, and special advanced film and material technologies to eliminate the focal plane shift of visible light and infrared light.
The special optical glass material solves the problem of infrared imaging, so that the visible light to the infrared light can be imaged at the same focal plane to achieve a clear image; special film technology allows infrared light to be as much as possible. Throughout; multi-layer coating can also minimize the occurrence of ghosting and flash under backlight conditions, even under adverse conditions such as backlighting can also get a relatively high-contrast high-quality images.
Infrared Lens Applications IR lenses have a wide range of applications. They can be used for both infrared and special applications as well as ordinary lenses.
In other words, according to different occasions, the infrared-compatible lens can be flexibly used in conjunction with conventional color cameras, black and white cameras, and day and night conversion cameras.
Black-and-white cameras do not have infrared cut-off filters, but the spectrum of daylight also contains infrared light, so even in daylight conditions, black-and-white camera imaging can suffer from infrared interference. Therefore, using an infrared lens can effectively improve the imaging quality.
