www.jedc.orgMeasuring the Diameter of a Human Hair by Laser Diffraction Introduction Often it is necessary to determine the diameter of a fine wire, thin thread or other object that cannot be measure by convectional means. These items can be measured by using methods of diffraction and interference known as Young’s Double Slit Experiment.

courses.physics.illinois.eduThe diffraction is already limited by D laser. Increasing D lens doesn’t help. There is a huge industry devoted to developing cheap blue diode lasers (λ~ 400 nm) for just this purpose, i.e., to increase DVD capacity. “Blue-Ray”technology! There are many times you would like to focus a laser beam to as small a spot as possible.

Custom Grating Sizes Available HANDLING OF GRATINGS The surface of a diffraction grating can be easily damaged by fingerprints, aerosols, moisture, or the slightest contact with any abrasive material. Gratings should only be handled when necessary and always held by the sides.
