  • Photothermal Lens Spectrometry Measurements in Highly Turbid Media 
    Marcano, Aristides; Basaldua, Isaac; Villette, Aaron; Edziah, Raymond; Liu, Jinjie; Ziane, Omar; Melikechia, Noureddine (University of Cape Coast, 2013)
    We measured the photothermal lens signal in samples exhibiting high turbidity using a pump-probe scheme. We show that the photothermal lens signal properties remain nearly unchanged up to values of turbidity of 6 cm1 despite ...
  • White light photothermal lens spectrophotometer for the determination of absorption in scattering samples 
    Marcano, Aristides; Alvarado, Salvador; Meng, Junwei; Caballero, Daniel; Moares, Ernesto Marin; Edziah, Raymond (University of Cape Coast, 2014)
    We developed a pump-probe photothermal lens spectrophotometer that uses a broadband arc-lamp and a set of interference filters toprovide tunable, nearly monochromatic radiation between 370 and 730 nm as the pump light ...
