LDI-4-488 SF Laser Diode Illuminator

The LDI-4-488 SF laser diode illuminator is a user inspired version of the LDI-4.  Many researchers were asking for a laser launch that covered only the 4 basic lines: DAPI, FITC, TRITC, Cy5. and specific 488nm laser  89 North listened and we responded.  The LDI-4-488 SF also features single 100 micron fiber output for applications such as TIRF.  The LDI-4-488 SF has only the lines you asked for.  While we reduced the number of lines inside the box, we made no compromises on the quality and performance you’ve come to expect from 89 North.  This unit is also available with a 470nm laser for FITC/GFP and with a 577nm laser for TRITC/mCherry…or both!

The LDI-4-488 SF is a multiline, solid-state laser illuminator offering 4 laser lines across the visible with powers up to 200mW. The unit offers feedback controlled output stability and up to a 100:1 linear dynamic range.  LDI-4-488 SF gets the job done with the same great performance found in earlier models

High output power Shorter exposures
Faster imaging
Faster activation times in optogenetics and photoactivation experiments
