LQ-LED-8channel

LQ-LED-8channel

This light source operates 8 individual LEDs. Customers can choose from a variety of different LEDs for application customization purposes. Each LED is coupled into one single fiber. The fiber bundle can be configured as required, e.g. crosshair, circular, rectangular. The arrangement of the fibers provides specific properties in various imaging applications, especially in KERR microscopy. The easy handling of the device enables you to reliably perform reproducible imaging tasks.
