Stable optical force
Power and pointing noise translate directly into force noise.

Optical tweezers
Create a quiet, stable trap for forces measured at the nanoscale.
Application focusStable optical force
TEM00 beam
Good beam quality supports a tight, predictable focus.
Living samples
1064 nm is widely used to reduce absorption and photodamage.
Why the source matters
Stable near-IR trapping minimizes photodamage while power stability, pointing stability, and beam quality set force stability.
The correct source is defined at the sample or process—not at the laser aperture. Wavelength and operating mode set the interaction; stability, delivery, timing, and control determine whether it stays useful in the complete system.

Application workflow
Design from the result backward.
Three decisions turn the application into a practical source specification.
Define the trap
Set particle or cell type, medium, objective NA, trap geometry, and required force range.
Budget power at the sample
Include isolation, expansion, steering, objective transmission, and split-beam optics.
Control force noise
Specify amplitude noise, long-term stability, pointing stability, mode quality, and thermal behavior.
Selection guide
Match the architecture to the experiment.
These are starting architectures. Precisometer qualifies the final wavelength, output, delivery, control, and integration package against your setup.
