  • Lasers and Collimation - Physics Stack Exchange
    If lasers are collimated, what causes them to decollimate? Their production system seems to suggest a completely linear, collimated light source, but they do spread out over large distances The same
  • What type of lens is used to collimate light? - Physics Stack Exchange
    It's difficult to further collimate such a beam I succesfully got better collimated beams from LEDs by grinding the front part, thus making a flat surface for the output of the light, and putting a lens after it
  • How can a lens collimate an image instead of just a point of light?
    1 A lens cannot collimate an image It can take the light from each point of the image into a collimated beam in a different direction Your eye can take a collimated beam and focus it to a point on your retina It can take beams in different directions and focus each to a different point, thus reconstructing the image Edit - A ray diagram
  • Is it possible to collimate a point source of concentrated light?
    The picture is misleading because it is not to scale (obviously), but the relationships still apply in any imaging situation You can collimate the light from the image of the sun - but because the image that you made has a finite extent, the collimated beam formed will have some angular spread - it will not be "perfectly" collimated
  • optics - Why cant incoherent light be collimated as well as laser . . .
    While you can collimate an LED, the fact remains that the because the LED has a much (much) larger angular spread than a laser, you just can't collimate it nearly as well So, perhaps you can get an LED down to a few degrees, but the laser will be in tenths of a degree That means the laser can go across a (big) room and still make a small dot on the screen
  • What is the best way to collimate light emitted by a LED?
    9 One cannot collimate light from an LED accurately without loosing a great deal of light and or being happy with a very wide collimated beam, because the source is often quite a wide extended source (sometimes up to 1mm across)
  • Can the neutrons in a nuclear reactor be collimated?
    This process reminds me a lot of the way lasers work, with essentially a mirrored "box" that contains the light and concentrates it before releasing it in a pulse So, my question is, could we collimate neutrons in a reactor in the same way we collimate light in a laser? Could we release them in a pulse? Could we essentially make a neutron laser?
  • optics - Collimating a UV LED - Physics Stack Exchange
    I have a task of narrowing a UV LED (375 to 400nm) of diameter 5mm to 1mm on the surface of an object The LED has a peak output power of 2 2mw (quite low) It has an half Intensity angle of 10 deg
  • optics - Does an aspheric lens require that the incident light be . . .
    Aspheric lenses are able to either collimate or focus light, depending on the side of the lens the light is incident In diagrams that show the aspheric lens focusing light, the incident light rays always look to be collimated
  • How can I collimate a laser beam of 100 wavelengths in vacuum?
    I'm asking in general how to collimate it, but my idea was use a parabolic mirror, then focus all wavelengths into a very short optical fiber, then get the light back into vacuum
