Optics
Welcome to Thorlabs; below you will find links to optical components and systems, a subset of our entire line of photonics products. All single element optical components can be found under the optical elements link with the exception of optical components that have polarization properties since they have a separate link. Multi-element systems like beam expanders and objective lenses as well as interferometers, fiber collimators, reference cells, modulators, and other optical devices can be found by choosing the optical systems link. Thorlabs also manufactures an extensive line of free-space and fiber optic isolators; stock items ship the same day that they are ordered while our custom orders benefit from our streamlined design and manufacturing process, which minimizes lead time.

Power/Position/Size Sensors
Thermal sensors that measure laser power and single shot energy like standard thermal sensors but in addition measure laser beam position and laser size. This position sensing detector measures laser beam position to 0.1 mm accuracy and laser size measurement of a Gaussian beam to +/-5% accuracy. Measuring laser position is important for laser alignment where the laser position sensor can provide feedback to the laser position control.

Weighing Instruments
ZhangZhou Weihua Electronic co.,ltd
are devices to measure weight or calculate mass. Spring balances or spring scales measure force (weight) by balancing the weight due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of a known mass or masses. Either type can be calibrated to read in units of force (weight) such as newtons, or in units of mass such as kilograms, but the balance or pair of scales using a traditional balance beam to compare masses will read correctly for mass even if moved to a place with a different (non-zero) gravitational field strength (but would then not read correctly if calibrated in units of force), while the spring balance would read correctly in force in a different gravitational field strength (but would not read correctly if calibrated in units of mass).

*Laser Thermal Power Sensors
Thermal sensors have a series of bimetallic junctions called a thermopile. Radial or axial heat flow through the sensor creates a voltage proportional to the power absorbed as it flows through the thermopile. The reading is not dependent on the ambient temperature since only the temperature difference is measured and not the absolute temperature. The thermopile elements are so arranged that the reading is almost independent of beam size and position. Generally, Ophir specifies ±2% or better uniformity of reading over the surface.
