Infrared LED

LED emitting collimated light

When an LED is used for optical encoders, it must emit a uniform, small spot light. L8506 is an infrared LED that emits such a light beam collimated by the combination of an aspheric lens. L8506 uses a non-confined structure chip that does not show an abrupt deterioration often encountered with some types of confined chips. The structure of L8506 is also designed to have high resistance to cyclic temperature changes so it copes with tough environmental conditions required for optical encoders used in factories.
