In addition to its invisible light output, the illuminators and heatsinks may

become warm during operation. Therefore the illuminators should be mounted

so as to minimize unnecessary skin contact. If illuminator mounting hardware

is provided, be sure to follow the assembly instructions, as these may affect

illuminator temperature. Ensure the illuminators are mounted so that air flow

is not excessively restricted, as this could also increase the temperature.

Mounting the illuminator so that it is clamped directly to a large piece of metal

will also help reduce its temperature.

The 910 nm infrared light from the illuminators is invisible under most

viewing conditions. A faint red glow may be visible in a dark room, usually only

after allowing 5 minutes your eyes to become dark adapted. NOTE: DO NOT

position your eye closer than 100 mm (4 inches) from the illuminator for an

extended period of time, as this may result in discomfort and unnecessary

exposure to heat and high levels of IR light.

The light output of the illuminators may change slightly for a period after

power is turned on to the camera and illuminators. For applications where

illuminators level is critical, it is recommended that at least 10-15 minutes be

allowed for the illuminators to reach a stable temperature before use. This

warm-up period will also allow the camera circuitry to reach its operating

temperature, resulting in best image quality at low light levels.
