iChrome SLE

Flexible Laser Engine with 8 Exchangeable Colors

  • Up to 8 diode laser lines in one box
  • Easy in-field-replacement of individual laser lines
  • Option: Two fiber outputs with integrated fiber switch
  • Integrated AOTF for modulation and power control
  • COOLAC – hands-off, self-aligning system

The multi laser engine iChrome SLE provides up to eight different colors from a broad selection covering 405 - 640 nm. Each color is housed in an individual laser cartridge which makes color changes fast and simple – even “in the field”. This great flexibility combined with two switchable fiber-outputs make TOPTICA’s iChrome SLE a great tool for demanding tasks like multi-color fluorescence microscopy.

TOPTICA’s ingenious COOLAC technology automatically aligns the system with a single push of a button. This feature ensures a constant optical output level even under strongly varying ambient conditions and completely eliminates the need for manual realignment - making the iChrome SLE the most flexible multi-line laser system on the market.
