ILD-QH-IR Halogen-SiN Source (350nm-30µm)

  • ILD-QH-IR Halogen-SiN lamp 350nm-30µm
  • ILD-QH-IR Halogen-SiN lamp internal components
  • ILD-QH-IR Halogen-SiN lamp connectors

Housing a 100W QTH lamp and a 40W SiN IR emitter with automated selection between the two, efficient coupling is ensured by CaF2 condenser lens (QTH) and an off-axis elliptical reflector (SiN).

Options include the integration of an optical chopper and quick change adaptor to facilitate mounting to monochromator entrance slit.

Stable operation of both sources can be ensured by using the 610 current stabilised lamp power supply.
