Are there many different types of illuminators?
An illuminator with a halogen lamp (a type of incandescent lamp) is frequently used for displays. The lamp is generally less expensive and has excellent color characteristics. Its total light flux is relatively low and bulb life may be short. For applications requiring brighter light‚ an illuminator with a metal halide (HID) lamp (a type of electric-discharge lamp) is usually specified. Metal-halide lamps may have longer lives, have higher total light flux‚ and a moderate to high-color temperature. These illuminators may be more expensive than halogen illuminators but they typically have longer bulb life and are significantly brighter. Neon-like brightness cannot be achieved with a halogen bulb and long lengths of 3M™ HL High Luminance Light Fiber. <>Newer models of high-performance light emitting diode (LEDs) lamps can also be used with 3M™ HL High Luminance Light Fiber. These new high-performance LEDs generate very high total light flux. The LEDs are small‚ light and energy efficient
Illuminators are used to provide a source of extra light where high brightness is required. Infrared illuminator is one of a kind which finds it uses in many fields related to security. These increase the efficiency of a security camera, as they capture images at night time without the need of any additional source of illumination. Other illuminators like one with metal halide are used when additional brightness is required to illuminate a place. There are other illuminators, as well which find their uses according to the needs.
