LDI-WF Laser Diode Illuminator for Widefield Microscopy
The LDI-WF is a powerful and inexpensive light engine designed specifically for widefield microscopy. This unit offers the same seven laser lines in the same power range as 89 North’s successful LDI, but delivers the light to your microscope via a 3mm Liquid Light guide. The LDI has built-in homogenization and our 555nm or 577nm laser diodes covers the ‘green gap’ common in other solid-state light engines.

LDI-5 Laser Diode Illuminator
The LDI-5 is the big sister of the LDI-4 laser diode illuminator. Once again we listened to our users who asked for a paired down version of the LDI-NIR. The LDI-5 has increased power over her little sister and expands into the near infra-red with the addition of a 730nm line. This unit is also available with a 488nm laser for FITC/GFP and with a 577nm laser for TRITC/mCherry…or both!
