The global Phototube Market size was valued at US$ 234 million in 2024 and is projected to reach US$ 321 million by 2032, at a CAGR of 4.2% during the forecast period 2025-2032

Phototube Market Overview

Phototubes are vacuum tubes or gas-filled tubes where the photoelectric effect is exploited. A phototube (or photoelectric cell), invented by Julius Elster and Hans Geitel in 1893, is a photoemissive detector based on a small glass tube containing electrodes where the external photoelectric effect (or photoemissive effect) is utilized. Such tubes are often evacuated or sometimes filled with a gas under low pressure.

The U.S. market size is estimated at USD 120 million in 2024, while China is projected to reach USD 95 million in the same year.

The Gas segment is expected to reach USD 180 million by 2032, growing at a CAGR of 6.5% during the forecast period 2026–2032.
