Introduction
This page contains all the devices I invented for optical tweezers (OT) and other optical-experimental setups. All the devices were made in very low budget and in short amount of time. Most of the devices are available commercially in one form or other, but these devices are specifically created to full-fill the requirements of optical tweezers which is designed but not limited to DNA-overstretching and unzipping.
Easy way to align two laser beams
In OT I use 1064nm IR laser for trapping, since it is invisible I align it with 633nm HeNe which helps me in number of ways: It let me align IR in farfield especially when i need to align the microscope and with HeNe it is easier to find the sample plane in eyepiece and camera. This post discusses the procedure-steps of alignment[1]
