Measuring just 48.92 mm in diameter and 60.04 mm deep, Polaris Industries' SUBCAM-CL infrared (IR) camera enables inexpensive imaging for underwater applications. Submersible up to 100 ft., its built-in white IR LED provides a 15-m IR range. With its heat- and water-resistant glass design, it can operate in rugged conditions.
The camera includes a 0.25-in. charge-coupled device (CCD) chip that supplies over 350 TV lines of resolution and a minimum illumination of 0 lx, with the IR imager on at a lens stop of F2.0 and a color temperature of 5600 K. It consists of an array of 542 by 496 CCD pixels and provides a 1-V p-p output into a load of 75 Ω.
Other features include an internal sync system, a signal-to-noise ratio of better than 45 dB with the automatic gain control (AGC) off, automatic white-color balancing, and a white-balance range of 3000 K to 5000 K. An electronic shutter spans the range of 1/60th of a second to 10−5 s.
The unit operates from a 12-V dc supply consuming 230 mA, and its IR portion requires 12 V at 150 mA. Its operating-temperature range is −20°C to 50°C. Rated to operate at a relative humidity up to 85%, it's made of aluminum with an original anodized finish. It also weighs just 150 grams.
Priced at $299.95, the SUBCAM-CL comes with an attached 20-m cable. The black-and-white SUBCAM-BW has an 80-m cable and costs $249.95.
