Day/Night Exchanger
Jun 2007
Sunex Inc.Request Info
Specifically Designed to Work with Pixim DPS Chipsets
CARLSBAD, Calif., June 4, 2007 -- Sunex has introduced a product that it said provides true day and night capability to C- and CS-mount cameras based on Pixim chipsets.

The new Sunex CSS-EXM-IRC21 is compatible with C- or CS-mount cameras and joins the existing M12-EXM-IRC21 with integrated lens mount (M12) in Sunex’s day/night switcher line, the company said. In low-light conditions the exchanger maximizes the light transmission to the sensor; in full-light conditions the exchanger optimizes the color rendition of the image.

One signal inserts the infrared (IR) cut filter between the lens and the sensor for daytime operation, optimizing the color rendition. The opposite signal exchanges the IR cut filter with a clear antireflective-coated window to maximize the light transmission in low-light conditions. The latching solenoid requires power only to switch, minimizing power consumption and heat generation, Sunex said.

The compact size is ideal for miniature cameras and allows the flexibly to choose different lenses based on application. With a small footprint and mounting holes designed specifically to mate with the Pixim reference PCB, both exchangers are drop-in solutions to make an existing camera design a true day/night camera, according to the company.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
