LDI-7 Laser Diode Illuminator

LDI-7

The LDI-7 laser diode illuminator is the most spectrally complete model in the MixxWave Gen1 range, covering 7 lines across the full visible spectrum — from 405 nm (DAPI) to 640 nm (Cy5) — including the 445, 520 and 528 nm lines unavailable on the LDI-4 and LDI-5. With up to 1000 mW per line and a 100:1 linear dynamic range, it provides the flexibility needed for complex multicolor fluorescence protocols in confocal, SIM, TIRF and PALM/STORM applications.

Key features

  • 7 laser lines across the full visible spectrum (405 nm to 640 nm)
  • Up to 1000 mW output power per line
  • No user alignment required
  • TTL & Analog control
