High-Performance Laser Diode Illuminators

The ldi family

The LDI is a multiline, solid-state laser illuminator offering up to 1000mW of output power via a multimode fiber at the price of a low power LED light engine. With feedback-controlled output stability and up to a 100:1 linear dynamic range, the LDI is the ideal light source for a wide range of applications including spinning disk confocal microscopy, structured illumination microscopy, FRAP, photoactivation / photoconversion, and PALM/STORM.

APPLICATIONS

  • Spinning Disk Confocal Microscopy with Crest X-Light
  • Super Resolution SIM Imaging with Crest VCS or Live SR 
  • PALM/STORM 
  • Optogenetics with DLPs or Multiport Illuminator
  • Photoactivation / Photoconversion / FRAP with RAPP GEO 
  • FRAP with SLM or Multiport Illuminator

Features and Benefits

High output power

  • Shorter exposures
  • Faster imaging
  • Faster activation times in optogenetics and photoactivation experiments
  • Faster bleaching times in FRAP experiments

Feedback-controlled optical stability

  • Quantitative imaging, ideally suited for ratiometric imaging
  • More repeatable optogenetics experiments

ease of use

  • Ability to turn power down when needed and maintain stability and quantitative imaging
  • Up to 7 lines covers most of the standard fluorescence probes
  • No user alignment
  • Easy to use and maintain
