Type Insights

The intrinsic optical sensors segment dominated the market and accounted for a share of over 55.0% in 2025. Intrinsic sensors measure various physical quantities such as strain, temperature, pressure, and more by modulating the intensity, wavelength, or time of light in fiber. Intrinsic optical sensors have fewer connection problems than extrinsic optical sensors and are also challenging to multiplexer. These sensors are majorly considered for distributed sensing over large distances. Typical applications of intrinsic sensors are used for rotation, acceleration, strain, and acoustic pressure. Innate sensors are resistant to electromagnetic interference and can operate in extreme temperatures. According to the May 2026 National energy technology laboratory, the distributed optical fiber sensing technique for power transformers employing optical frequency domain reflectometry (OFDR) has been developed by the NETL of the U.S. Department of Energy and Carnegie Mellon University (CMU).This method makes it possible to analyze instantly and accurately the temperatures and strains in transformer components, thus enabling the timely detection of problems in high voltage environments with electromagnetic interference.

The extrinsic sensors type is projected to grow at the fastest CAGR over the forecast period. Extrinsic optical sensors transmit modulated light from a non-fiber optical sensor coupled to an optical transmitter via optical fiber. These sensors use optics to extract the light from the fiber and modulate it in another medium. They measure vibration, rotation, displacement, velocity, acceleration, torque, and temperature.

Sensor Insights

The increasing adoption of Industrial Internet of Things (IIoT) technologies and smart manufacturing processes has increased demand for temperature sensors. Accurate temperature monitoring ensures efficient operation and prevents critical failures in the renewable energy sector and conventional power generation. The growth in the renewable energy sector presents significant growth opportunities for optical temperature sensors.

The biomedical sensors segment is projected to grow at the fastest CAGR over the forecast period. A biomedical sensor is an electronic device that transfers various non-electrical quantities in biomedical fields into easily electrically detectable amounts. Due to this reason, these sensors are included in health care analysis. This sensing technology is the key to collecting human pathological and physiological information.

Application Insights

The biometric applications segment dominated the market in 2025. A specialized sensor is necessary to determine a biometric signal. The particular type of sensor employed depends upon the measured biometric signal. The inclusion of a biometric sensor in the contactless payment card enables individuals to personally verify each transaction using a distinctive credential, such as their fingerprint. The increase in contactless payment globally is expected to increase the demand for biometric optical sensors. For instance, in December 2025, M-Tech Innovations received Visa Certification for India’s first-ever locally developed biometric payment card that can authenticate the identity of an individual through fingerprints, enabling PIN-less payments.

The temperature sensing application is projected to grow significantly over the forecast period. Progress in materials science and optical technology has resulted in the development of sensors with enhanced temperature detection precision. It involves leveraging novel materials to improve both light modulation and detection. These sensors are now more frequently incorporated into IoT setups and intelligent networks, finding applications across diverse sectors such as residential automation, industrial control, and healthcare.

End Use Insights

The consumer electronics segment dominated the market in 2025. The consumer electronics industry has seen a surge in the integration of optical sensors due to their versatility and applicability in various devices. These sensors, including ambient light, proximity, and image sensors, have become fundamental components in smartphones, smartwatches, cameras, and augmented reality (AR) devices. Smartphones utilize ambient light sensors for automatic screen brightness adjustment and proximity sensors for screen activation during calls. For instance, in June 2025, the ams OSRAM showcased advanced ambient light, proximity, spectral and CMOS imaging sensors at the Sensors Converge 2025 aimed for use in smartphones, wearables and AR/VR devices. The company highlighted small form factor and power-efficient optical sensing solutions that enhance capabilities such as auto-brightness control, proximity detection, gesture recognition and 3D sensing.

In addition, image sensors enhance camera functionalities, enabling high-resolution photography and advanced features like depth sensing and facial recognition. Increasing smartphone adoption is expected to fuel the demand for optical sensors. According to the May 2025 Ministry of Statistics & Programme Implementation in 2025 Comprehensive Annual Modular Survey (CAMS), 85.5% of Indian households own smartphone, whereas 86.3% of households have Internet access, highlighting the rapid pace at which smartphone and Internet usage have been spreading in India.

The healthcare segment is projected to grow at the fastest CAGR over the forecast period. The use of optical sensors in healthcare has grown significantly due to technological advancements and the increased need for precise and economical diagnostic tools. These sensors are applied across patient observation, imaging, diagnostics, and therapy. For instance, pulse oximeters, relying on optical sensors to measure blood oxygen levels, have become pivotal in healthcare. Optical coherence tomography (OCT) systems also offer detailed images in fields like ophthalmology and cardiology, aiding early disease identification.
