Just as its name implies,1/3’’ Series Fisheye Lenses were made for camera with 1/3'' or smaller sensors. Among the lenses of this series, CH2503 provides a ultra wide angle of view as 225 degrees well beyond a normal field of view and comes with two types of mount-M8 and M12. Its compact dimension-ф14.00*L13.10mm makes it perfect for applications in smart home, like motion sensors, entry sensors, video doorbells etc, where there's always limited room for lenses.
CH2503 is designed to provide a maximum ф3.1mm image circle. In combination with a 1/3 inch sensor, such as OA4689, fisheye lens CH2503 produces a circular image like this →These lenses are composed of glass optical lenses and metal housing, therefore they can work under extreme high and low temperature. They are designed and used in a variey of applications including 360VR, Vehicle surround view, industrial applications,etc. With or without IR Filter options are available for all these lenses. And there are a wide range of filters to choose from.
