Infrared detectors are generally classified as being either thermal or photon (quantum) detectors. Lead Sulfide (PbS) and Lead Selenide (PbSe) detectors are both members of the lead-salt family of ...

ID Quantique SA: ID Quantique SA has made a significant stride in the industry with the introduction of its ID230 infrared ...

Hamamatsu Photonics is excited to announce the expansion of its multi-pixel photo counter (MPPC) product line with its latest ...

The detection of light at the single-photon level is important for tasks ... because the act of switching causes it to emit a few infrared photons. This has allowed computer chip designers to ...

While confocal microscopy uses a pinhole to reject out-of-focus light to generate the optical section, a multi-photon (or 2-photon) microscope uses a pulsed infrared laser to stimulate fluorescence ..

Two-photon vision is a phenomenon in which the human eye can perceive ultrashort pulses of infrared lasers with a wavelength in the range of 800–1300 nm by absorbing two photons. This process ...

Using Fourier-transform infrared (FTIR) spectroscopy ... Ppy-I nanocomposite as a high-performance material for single photon detection and other optoelectronic applications.
