Shielded side-window PMT detectors for low-light measurements on monochromators, spectrographs and sample chambers.
PMTH-S1 detectors house a side-window photomultiplier tube in a light-tight enclosure with electromagnetic and optical shielding, designed to mount on Omni-λ series monochromators/spectrographs and sample chambers. Several side-window tubes can be fitted, with spectral responses from 185 nm up to 900 nm. The matching HVC1800 high-voltage power supply provides the stable negative bias required for low-level photometry and photon counting.
Key Features
- Side-window PMT in a light-tight housing with electromagnetic and optical shielding
- Matched to Omni-λ series monochromators/spectrographs and sample chambers
- Signal output through a standard BNC; high voltage fed through a dedicated HV-rated BNC
- Current output as standard, voltage output optional
- Choice of built-in tubes: CR316-02, R1527, R1527P, CR131, CR131A, R928, R2949
- Optional HVC1800 supply: 0–1500 V DC negative, set manually or by an external 0–10 V signal (e.g. from the DCS300PA)
Typical Applications
- Low-light photometry
- Single photon counting
- Fluorescence and luminescence spectroscopy with scanning monochromators
- UV–visible spectral measurements
