Overview

PMT bare tube with wide spectrum and high gain is a side window type photomultiplier tube designed specifically for low light precision detection. Using quartz glass windows and multi alkali photocathodes, the spectral response covers 165-900 nm (deep ultraviolet to near-infrared), and a 9-stage ring doubling structure achieves high gain of 10 ⁶ -10 ⁷ and nanosecond fast response. It is widely used in environmental monitoring, semiconductor detection, fluorescence analysis, chemiluminescence detection, and photon counting, and supports customized sensitivity, gain, and structure according to drawings.

Photomultiplier Tube PMT Bare Tube – Wide Spectrum 165–900 nm, High Gain 1×10 ⁷, Customizable

Brand:TAOMSUN ｜Overseas Tech Support:METICULAB (Korea) ｜Model:TS-PMT-SD9 · Side-on · Quartz Window · Multi-Alkali Cathode

TAOMSUN PMT bare tube (TS-PMT-SD9)is a side-on photomultiplier tube designed for weak-light precision detection. Featuring a quartz glass window and multi-alkali photocathode, it covers a spectral response range of 165–900 nm (deep UV to near-infrared). With a 9-stage circular dynode structure, it achieves high gain of 10 ⁶–10⁷ and nanosecond-level fast response. Sensitivity grades, gain, and structural dimensions can be customized per drawings.

🔍 Key Features:wide spectral response 165–900 nm (deep-UV extension); high gain up to 1×10 ⁷ (single-photon level); fast response – rise time 2.2 ns, TTS 1.2 ns; low dark current 3–50 nA; quartz window (short-wave limit 165 nm); multi-alkali cathode (UV-VIS-NIR); 9-stage circular dynode; full customization per drawings.
