LS2 White Light Source Overview

LS2 white light source | Hansatech Instruments | Oxygen electrode and chlorophyll fluorescence measurement systems for cellular respiration and photosynthesis research

The LS2 light source is a high-intensity (100W) tungsten-halogen light source which is powered from a stabilised power supply.

The lamp housing contains a cooling fan, infrared reducing “Hot-Mirror” and optics to provide light with minimum variation of intensity across the beam and little divergence from parallel. 2 slots are provided to accept 50mm square optical filters or a manual shutter-plate.

A range of light intensity steps may be achieved by adding permutations of the 4 A5 neutral density filters supplied (0.1,0.3,0.6 and 1.0 O.D.) to attenuate the light intensity. Maximum sample illumination intensities vary depending on the type of electrode chamber in use.

When used with the DW1 electrode chamber the LS2 can achieve a maximum intensity of 1,800 µmol m-2 s-1 when mounted horizontally with respect to the electrode chamber.
