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.
