A conventional intensified optical multichannel array detector (I-OMA) with minor modifications can detect organic monolayers at "counting rates" as low as 0.05 photoelectrons per second per pixel. Both hardware modifications and data analysis techniques are presented that allow one to obtain maximum performance from the conventional I-OMA.
