Overview

The Theia Technologies CS-Mount 9-40mm f/1.5 5 Mp Telephoto Day/Night P-Iris Lens provides more precise iris control with compatible cameras. The P-Iris lens works with a P-Iris camera’s specialized software to gauge the best iris opening and optimize camera settings to get excellent overall image.

The size of iris opening and amount of light allowed in a lens affects the image exposure, sharpness, and depth of field. Working in conjunction with the P-Iris lens, the camera uses electronics to manage slight changes in lighting conditions to balance these sometimes conflicting demands and optimize an image. In situations when the iris position and the camera’s electronic processing capabilities cannot adequately correct the exposure, a P-Iris camera will automatically instruct the iris to move to a different position. In bright situations, a camera with P-Iris is programmed to limit the closing of the iris to a position that avoids diffraction or blurring, providing a sharper image.

The lens features a focal range of 9 to 40mm providing 36 to 7° horizontal field of view with 4.5x optical zoom and 16x digital zoom capability allowing the user to drill down into the image capturing subjects in high detail. The P-Iris feature adjusts the iris opening to further improve the depth of field, or the distance in front of and beyond the point of focus where objects appear to be sharp simultaneously. This is particularly important in the video surveillance of a long corridor or parking lot.

The CS-mount lens was designed to cover 1/2.5" imagers and smaller including 1/3", 1/2.7" HD size sensors.
