Pyroelectrics vs. Thermopile IR Detectors Pyroelectrics vs. Thermopile IR Detectors

Thermopile IR detectors are thermocouples made from dissimilar materials with differing Seebeck coefficients. The Pyroelectric effect in is manifested in dielectric materials which have a crystalline asymmetry such that its polarization is changed when its temperature is changed.

  • Camera System Gives Tunneling Machines New Sights

  • Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

  • Understanding Virus Mechanisms — One Particle At A Time
