Blue-X-Lite (LED light source)

The Blue-X-Lite is a entry-level professional flicker free lighting solution for DIC. Short wave length, small bandwidth, pulse mode, focusable

  • The Blue-X-Lite can be used in continuous wave mode (CW) or in pulsed mode (Pulse) with 20 W. Due to its fast rise times < 100 ns in combination with special trigger unit it is also suitable for synchronization with DIC systems with stroboscopic illumination.
  • Light intensity can be controlled stepless up to  60% light intensity for continuous wave mode (CW) and 100% light intensity for pulse mode (Pulse).
  • Frame rates: Two versions are available with trigger frequency up to 1,000 Hz or 10,000 Hz.
  • The Blue-X-Lite can be easily attached directly to the stereo bar by flexible arms for individual adjustment of the light direction.
    The fanless design offers the advantage of no vibrations transmitted to the stereo bar.
  • Mounting: 1/4″, 3/8” and M6 threads for tripod or flexible mounting arms (bottom). M4 threads (front) for mounting to VIC-Professional fine adjustment camera mounts.

Blue-X-Focus – LED light source

The new LED light source with 100W power and up to 200W in pulse mode

The Blue-X-Focus is a powerful LED light source, especially designed by isi-sys for digital image correlation:

  • The short, single wave length (blue) improves the optical transfer function properties especially a) at the image boarders for conventional lenses and b) for high resolution, small FOV set-ups such as the Micro 3D stereo sensor.
  • The pulse mode reduces motion blur and maximizes light power at lowest possible heating of the object surface
  • Large beam expansion range from 5° to 60° for small to large field of view. Operation through small windows
  • A polarization-filter (optional) is suppressing direct reflections in combination with a second pair for the sensors
  • The short wavelength can be used in combination with bandpass filters for measuring on hot samples

Further details:

  • Power: Standard operation with 100W in continuous mode or 200W for pulse mode depending on duty cycle. Example for 0,7 duty cycle: 105W @ 240Hz and 2,9ms flash period. Power adjustable manually or external by pulse length and frequency as well as automatically limited depending on temperature.
  • The focusing adapter for standard DIC is from 5° to 60° expansion.
  • Mounting is possible horizontal or vertical via  ¼” threads
  • The cooling air stream is directed from the front inlet to the backside to avoid hot air waves in the images.
