Optical Tweezers#

Optical tweezers trap and manipulate particles using focused laser beams. Their operation is precise but extremely sensitive to sample properties and optical stability.

Dimensional Core (SET)#

• Spin: polarization effects
• Elec: optical/electronic detection
• Temp: local heating effects

Why Red‑Zone#

Optical tweezers operate in a fragile, nonlinear regime.
Sample composition, refractive index, and laser stability strongly affect results.

Regime Notes#

• pos‑regime: stable samples, controlled optics
• Q‑regime: refractive mismatch, drift
• neg‑regime: heating, photodamage, unstable traps

Containment Notes#

Requires explicit optical‑stability and sample‑property boundaries.
