IntraLED 3 - LED Cold Light Source intraLED 3

  • High luminous flux (>500 lm) and excellent light uniformity
  • Long lifetime (50,000 hours = 5.7 years in continuous mode)
  • Low power consumption compared to halogen light sources
  • Compact aluminum enclosure is easly integrated (threaded rails on 4 sides)
  • Compatible with light guides from Volpi and Schott-Fostec

The new LED light source intraLED 3 is the ideal lighting system for machine vision and industrial microscopy applications. It emits a very intense and uniform natural light.

The compact enclosure allows it to fit in tight spaces and provides smooth system integration. A real alternative to halogen light sources, the intraLED 3 offers significant cost savings and is environmentally friendly.

V-Lux 1000 - Cold Light SourceV-Lux

 The V-Lux 1000 is a low-cost quality fiber optic cold light source featuring many high-end features such as compact design, constant color temperature, long lamp life and low noise/vibration.

  • Ideal for Microscope Illumination
  • Constant color temperature and light emitting angle
  • Continuous intensity adjustment via crescent shaped diaphragm
  • Low-cost alternative to the Intralux series
  • For use with fiber optic ringlights, goosenecks, and flexible light guides

The V-Lux 1000 is ideal for any microscopy application, because it provides reliable, dependable, high-intensity cold halogen light. It was designed for use with all Volpi fiber optic components in microscopy applications. Although it is factory equipped with DDL Lamps, EKE bulbs may be easily substituted for slightly more light output. It has an integrated resettable fuse transformer. Non-120V power supply systems available. Ringlights and flexible fiber optic light guides purchased separately.

NCL 150 - Cold Light SourceNCL 150

The NCL-150 will provide reliable, dependable, high-intensity cold halogen light.

  • 20V/150W
  • Constant color temperature
  • Continuous intensity adjustment brightness
  • High/Low setings
  • Filter shot
  • Use of DDL or EKE bulbs
  • Long lamp life
  • Low noise/vibration
