Goniophotometers GO-DS 1600/2000
GONIOPHOTOMETERS WITH MIRROR ARRANGEMENT
Applications
  • Measurement and evaluation of light technical characteristics of lamps, luminaires, floodlights, and any other light source for product development, documentation, quality control, research, and education in lighting industries and at test laboratories, governmental institutes, and universities
Characteristics
  • Goniophotometer with mirror
  • Light source remains in its dedicated burning position
  • Lamps, luminaires, and floodlights of all kinds can be measured with highest accuracy
  • Designed for light sources with characteristics dependent on their position (luminous flux, intensity distribution, temperature, geometry, or mechanical stability)
Versions
  • GO-DS 2000 for test samples of maximum size of 2.0 m and 50 kgs
  • GO-DS 1600 for test samples of maximum size of 1.6 m and 50 kgs
Goniometer
  • Stable mechanical base with luminaire and mirror turning axis
  • By use of a special transmission the light source axis is rotated around the mirror axis while remaining in a constant position
  • The luminaire axis can be rotated around 180° for pendent or standing burning position
  • Wiring for electrical supply and measurement is integrated and connected via precision slip ring contacts to the test sample
  • The continuously rotating light source allows smooth movements and shortest measurement times
  • Precision DC motor drives with seven speeds for light source and mirror axis
  • Absolute angle encoders with 0.1° accuracy for both axis
  • Motoric adjustable counter weight
  • Motoric adjustable test sample position
  • Built-in adjustment laser
  • Safe operation by safety clutch and controls, TÜV certificate available
Mirror
  • Mirror in center position
  • Stable adjustable mirror base
  • Selected flat mirror
  • Variation of reflectance and flatness tested acc. to BSI and CEN standard
  • Elliptical shape
  • Mirror dimensions:
    • GO-DS 1600 ab. 1500 mm x 2200 mm
    • GO-DS 2000 ab. 2000 mm x 2800 mm
Photometer
  • Accuracy class L (highest accuracy) acc. to DIN 5032 part 7 including the mirror characteristics
  • Highest precision system-photometer head, thermostated, built-in amplifier and tube for straylight reduction
  • Display unit with calibration in lx and cd for multiple photometer heads
Measurement and Control Unit
  • Digital display of photometric values, angles, and rotation speeds with devices for manual control, remote control, safety controls, test circuits, computer coupling with IEEE-488 Bus Interface
Options
  • Additional photometer heads with stray light tubes and tripods for additional photometric distances
  • Secondary mirror device for extension of the photometric distance
  • Electrical power supply and indicating instruments for test lamps
  • Remote control close to the goniometer with display of photometric values and angles for manual control during mounting and adjustment of test samples
Computer, Software and Services
  • Personal computer and LMT LIMES 2000 Software for automatic measurement and evaluation
  • consulting, user training, mounting, and service
