Buying Optical Sensors
Optical sensors measure various quantities such as dimensions, distances, forces, pressures, strains, stresses, deformations, and temperatures. Some systems offer distributed sensing along an optical fiber.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

![]() Bringing light to measurement HBK FiberSensing, S.A.Via José Régio, 256 4485–860 Vilar do Pinheiro Portugal |
The newly developed optical sensor line newLight enables large strain measurement ranges at increased long-term stability. It is the ideal choice for structural health monitoring due to its fast and easy installation and its resistance to environmental conditions such as humidity, rust, and salt even over extremely long distances. The compatibility with standard telecom cables makes this line very cost efficient – especially for medium-to-high channel applications. The newLight range is based on the Fiber Bragg Grating technology and offers optical sensors for measurements of strain, temperature, accelerometer, and tilt. In addition to fiber optical sensors that measure strain, temperature, acceleration, tilt or displacement, HBK also offers optical interrogators, software, as well as service and support for every application.
