As part of regular product care CAL Sensors will be introducing another
basic improvement to the linear multiplexed array (LMA) product family
in the fourth quarter of 2011: Of the 256 pixels in total, the three
outer pixels at the beginning and at the end of the line are blacked
out. They serve as reference points for temperature regulation. With
this trick, the time interval between reference measurements can be
significantly increased. The dark signal pattern of this series is five
times more stable than the preceding series; it enters a range that was
previously only seen with photodiode arrays.
The multiplex arrays are available from Laser Components.
