A smartphone-based near ultraviolet (UV) colorimeter is demonstrated for the first time using an external UV LED source (Δλ ≈ 365 − 415 nm) and the inbuilt CMOS camera of a smartphone.
A smartphone-based spectrometer employing principle of diffuse reflection is reported for the surface analysis of solid samples.
A self-contained smartphone-based near infrared (NIR) colorimeter is reported for the first time by utilizing the inbuilt NIR emitter (λ ≈ 770-1000 nm) and macro-lens complementary metal-oxide semiconductor (CMOS) camera of the phone.
