IMAG-MAX/LR

Accessory

LED array when red excitation light (650 nm) is required

  • Overview
  • Specifications
LED array unit in black anodised aluminium housing with central lens aperture, cooling fan, heat sink vents, sensor mount and grey cable connection

The LED Array is mounted on a printed circuit board in an aluminium housing with a central opening for lenses of IMAG-K7 or IMAG-K9. A fan on the top side provides the necessary cooling. Cable connections to the IMAG-CG Multi Control UInit and the external 300 W power supply exit the rear of the housing. An appropriate filter plate is included; not compatible with filter plate IMAG-MAX/F for IMAG-MAX/L
