An illuminating optical lens article of manufacture for use with a light emitting diode (LED) mounted on a circuit board is provided. The lens has (a) a base portion defining a rim on a plane having a bottom surface around a longitudinal axis for mounting over the LED; (b) an integral refractory outer surface of the lens extending towards the longitudinal axis from the base; (c) an integral refractory inner surface of the lens extending from the base forming a cavity shaped and sized to receive an LED; and optionally (d) a plurality of grooved sections for receiving an adhesive formed on the bottom surface of the base portion. The base is adapted to be mounted on the circuit board onto which the LED is mounted. The integral refractory outer and inner surfaces each define a predetermined geometry adapted to direct and focus light emitting from the LED to a predetermined path. The lens is fabricated with a tolerance range of within 0.15 mm or better. The lens can be incorporated into a luminaire system and mounted on to a circuit board using adhesive polymers. The assembly of the lens into the luminaire system can be automated using robotics.
