LH36/2R Light Source

LH36/2R LED light source

  • High-intensity light housing with 36 red LED’s centred on 650nm
  • Compatible with DW3, LD1/2 & LD2/3 electrode chambers
  • Max. intensity up to 900 µmol m-2 s-1 in DW3 & 750 µmol m-2 s-1 in LD1/2 & LD2/3
  • Requires Oxylab+ control unit for calibration & automatic control of intensity changes.

LH36/2R LED Light Source Overview

The LH36/2R light housing is designed specifically for use with the DW3 chamber. The light housing mounts directly on to the larger optical port of the DW3 and is held securely in place.

The large-area LED array consists of 36 red LEDs arranged in such a way to provide a high uniformity of illumination of laminar samples suspended in the square section chamber of the DW3.

LH36/2R connects directly to the rear of the Oxylab+ electrode control unit. Light intensity adjustments are made automatically based on user-defined PFD tables within OxyTrace+ software. PFD tables consist of up to 20 individual steps allowing complex light response assays to be configured for automatic execution during a measurement.

The LH36/2R has an integral cooling fan which automatically switches on to cool the housing when the light intensity reaches a certain point. This provides stability control of the light intensity when required at higher light intensity steps. Optical feedback controls within the light housing serves to enhance the stability of the LH36/2R performance across the entire range of intensity.
