Exercise 2.3 - Optical Tweezers
Content of the work
Content of the work
In this experiment, we will investigate the trapping and manipulation of micro-sized particles by using the optical tweezers. The work illustrates that light can be used to generate mechanical forces on the particle. In the laboratory you will learn about the operational principle of optical tweezers and the associated lab equipment. The practical aim is to determine the magnitude of the force exerted from the light on the particle and to manipulate the particle position and movement in a controlled manner.
Schedule
Link to the remote exercise registration is here. Reservation is open until 31.3.2021. Maximum number of students
accepted to this exercise is 15. You need to request for the model data
from the assistant by the end of March (at that time the model data
will be automatically sent to those participants who had not yet asked
for it).
The first version of the report must be returned to the exercise assistant electronically no later than three weeks after the model data has been received. The writing time for the second revised version, in turn, is two weeks, calculated from the assistant's invitation to the feedback session.
The reports will be returned to the assistant by email.
Material and measurement
Before requesting the model data, read carefully the instructions, where more information on the experiment and report can be found. In addition, watch the demonstration videos carefully and read the sections "Kurssin suorittaminen" and "Selkkariohjeita" in MyCourses. Then request the model data from the assistant.
