By using innovative optical designs, efficiency between the lamp and the fiber coupling has been
dramatically increased. This enables lamp life to be extended by a factor of five, with no loss in
light output. For example, using a standard 150 Watt EKE quartz halogen lamp, with the
illuminator at full intensity, lamp life is increased from 200 to 1,000 hours. A slide potentiometer
adjusts lamp intensity from 0 to 100%. Optional iris dimming is available when constant color
temperature is required.
