LDI-4 Laser Diode Illuminator

The LDI-4 laser diode illuminator is a user inspired version of the original LDI-7.  Many researchers were asking for a laser launch that covered only the 4 basic lines: DAPI, FITC, TRITC, Cy5.  89 North listened and we responded.  The LDI-4 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 488nm laser for FITC/GFP and with a 577nm laser for TRITC/mCherry…or both!

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

    LDI-Prime Laser Diode Illuminator

    The LDI-PRIME laser diode illuminator was designed specifically for those researchers whose work demands the 488nm laser.  As this is a premium laser line, we combined it with a collection of 3 other lasers to cover the visible spectrum as simply as possible to give you the power and the performance you need at a price that you can afford.  To keep it simple we also combined all the lasers into a single 400um fiber optic output.
