LDI-NIR Laser Diode Illuminator

LDI-NIR

The LDI-NIR is the same great multiline, solid-state laser illuminator as the LDI-7, but offers more power and extends the range into the near-infrared. This affordable multimode laser launch redefines the standards of laser illumination.

Key features

  • 7 laser lines from 405 nm to 730 nm (full visible + NIR)
  • Up to 1000 mW output power per line
  • Dedicated 730 nm NIR channel for deep-tissue imaging & multiplexing
  • No user alignment required
  • TTL & Analog control
