Abstract: A night vision attachment for a SmartPhone by which the camera of the SmartPhone is enabled to view or take digital photos of objects under very low light ambient light levels. The night vision attachment comprises a housing for receiving and locating components of the attachment and has portions adapted to mate with a wall of the camera through which the phone camera lens images object space. Located in the attachment housing are an image detector sensitive to infrared (IR), an objective lens for forming images on the image detector whereby the image detector operates to generate image output signals representative of detected images, a display arranged to receive the image output signals from the image detector and to generate a visible image; and an eyepiece for viewing images formed on the display and permitting the camera of the phone to focus on the display images when the attachment is mated to a phone. IR LEDs are used to illuminate scenes.
