Named after the inventor Marcel J. E. Golay, these bolometers use a gas-filled chamber with a flexible membrane that absorbs incident infrared radiation, causing pressure changes that are measured using a photodetector. Golay cell bolometers are known for their high sensitivity and have applications in spectroscopy and scientific research.

These are miniaturized versions of bolometers typically fabricated using microelectromechanical systems (MEMS) technology. They are widely used in thermal imaging cameras, night vision devices, and security systems due to their compact size, low cost, and ability to operate at room temperature without requiring cryogenic cooling.

Each type of bolometer offers unique advantages suited to specific applications, ranging from high sensitivity and precision in scientific instruments to robustness and affordability in commercial and consumer devices. The choice of bolometer type depends on factors such as required sensitivity, response time, operating conditions, and cost considerations within the intended application.

Global Bolometer Market, Segmentation by Material

The Global Bolometer Market has been segmented by Material into Metal, Semiconductor, Superconductor.

The global bolometer market is segmented by material into three primary categories: Metal, Semiconductor, and Superconductor. Metal-based bolometers are widely used due to their durability, cost-effectiveness, and stable performance over a broad temperature range. These bolometers rely on the temperature-dependent resistance changes in metals, such as platinum or nickel, to detect infrared radiation. They are commonly used in industrial and military applications where robustness and long-term reliability are essential.

Semiconductor bolometers offer higher sensitivity and faster response times compared to their metal counterparts.
