iChrome CLE

Efficient and compact Four-Color Laser Combiner

  • Four colors in one compact box
  • 405, 488, 561, 640 nm with > 20 mW each
  • COOLAC automatic alignment
  • Unique modulation capabilities
  • Complete off on all wavelength

TOPTICA's iChrome CLE is a compact laser engine that combines four laser lines in one box. All integrated colors are provided via one polarization-maintaining single-mode fiber. It is available with 405, 488, 561 and 640 nm and up to 20 mW guaranteed output power after the fiber for each laser line. The system guarantees a plug & play installation since it includes TOPTICA's proprietary COOLAC automatic alignment technology.

  • iChrome CLE, four colors

This way the laser combiner system is ready-to-use after one simple click of a button. 561 nm laser light is generated by TOPTICA´s proprietary FDDL (Frequency Doubled Diode Laser) technology. Each laser line, including the 561nm FDDL, can be directly modulated up to a frequency of 1 MHz and TOPTICA's "Complete OFF" mechanism guarantees zero photons in the "off"-state.

The iChrome CLE is designed and optimized for confocal scanning microscopy or other microscopy techniques requiring laser modulation. Modulation behavior is thoroughly tested at TOPTICA, to guarantee best performance at the customer’s site. Of course the unit is equally suited for other imaging techniques, which do not require modulation, but do work with the specified power levels.
