Одноэлементный detector type PTA-928

Single-element detectors from SOL instruments

SOL instruments offers a full family of single-element detectors for the spectral range of 0.185 – 16.6 μm. All detectors, as well as accessories for connecting them to monochromators, are optimized to maximize the SNR in the spectroscopic system. We offer both: detectors based on Photomultiplier tubes and solid-state photodetectors. We can provide photosensors without cooling, with TE (thermoelectric) cooling and liquid nitrogen cooling to fulfill the most demanding spectroscopic applications at an affordable price.

Using single-element detectors, it is important that all the light from the output of the monochromator falls on the photodetector active area. We offer mirror and lens adapters, allowing the monochromator output radiation to strike the detector active area without any losses. All the detectors have standard mounting flanges for attaching them to the output slits of our spectral devices. For maximum efficiency in the IR range, we offer monochromators with silver and gold mirror coatings, as well as gold coated gratings.

SOL instruments also supplies the SpectraDAS (three-channel data acquisition system), the SpectraLIA (two-channel lock-in amplifier) and all other electronics used for signals acquisition with single-element detectors.

Lock-in amplifier SpectraLIA


Two-channel single-phase lock-in amplifier, which, together with an optical radiation modulator, can measure periodic useful signals with a predetermined frequency against a background of very strong interference, the magnitude of which can exceed tens of times and hundreds of times the amplitude of the useful signal that needs to be measured.

Система регистрации SpectraDAS


High performance three-channel Data Acquisition System for spectroscopy, compatible with all SOL instruments DC voltage output detectors as well as our photon counting detectors, and, in general, all types of integral detectors, such as diode detectors and PMTs, except for detectors requiring modulation of the luminous flux and a lock-in amplifier.
