I Optics Research Issue

  1. Mar 31, 2017 #1
    Greetings,

    I am a student doing research and I have a diverging LED array light source outfitted with a diffuser and I need it to focus to a beam width of smaller than 5mm in order to image a optical trapping on a CCD camera. My apparatus has about 10cm of space underneath it, so I have to be able to fit my light source and whatever lens configuration in that 10 cm distance. Basically, I need a cheap lens solution in order to focus as much light as possible in a very small beam with a short focal length (<10cm). Any suggestions?

    Are you asking what type of lens you need, or are you asking where you can purchase the lens you need?

    Welcome to the PF.

    What is a "diverging LED array light source"? Can you Upload a sketch of your setup?
