We test the ISO of every Phantom camera model to the industry standard ISO 12232. When it gets to the hot side of the pipe, it will turn to vapor and circulate back to the cool side where it gives up heat and turns back into liquid. Liquid in the heat pipe moves toward the source of heat through capillary action. The other side is bonded to a heat sink which is fan cooled. One end of the heat pipe is bonded to the source of heat, in this case the copper heat sink. The heat pipe is a copper tube that is filled with a liquid under low pressure. The heat pipes carry excess heat away from the sensor area toward the sides of the camera where heat is removed using dual fans. On these cameras the sensor die is attached to the TE cooler, which in turn is bonded to a copper heat sink which has heat pipes attached. However, these cameras run so fast, that additional cooling technology is employed. This technology is used on the v2512, v2012, v1612 and v1212. The TE cooler is typically bonded to a heat sink cooled by an active fan-based cooling system. The sensor die is attached to the TE cooler and by monitoring the temperature of the sensor, the camera can supply more or less power to the TE cooler to adjust the temperature. For many years, Vision Research has used thermo-electric (TE) coolers based on the Peltier effect to control sensor temperature. By keeping the sensor at a fixed temperature, you will get better, more repeatable images. To minimize noise and maximize image quality on any digital high-speed camera, it is important to control the sensor temperature.
