How to Align Lasers | Edmund Optics

Pro tip: center the beam to the target with the near mirror then move the target to the far side.

Now say the beam is lower than the target ~10mm from center, raise it with the far target mirror so it’s ~10mm above center INSTEAD of making it center. The same holds true for side to side movement.

Come back to the near target and make it dead center with the near target mirror.

When you come back to the far target the beam will be much closer to being lined up than if you had gone to the center the first go around.

For example if you had gone to center on the far target the beam is 9mm lower the second go around but if you overshoot it it’s 6-5mm lower.

Repeat until both targets are centered.

This is called overshooting and will cut the alignment time in half. Think of it as taking baby steps vs proper steps.

This is specially useful when the beam is infrared and you have to take paper shots. Seeing the beam makes it 10 times easier.

There are other techniques but this one is the easier one for people to understand.

sir can we use a autocollimator to align a laser with its pilot lamp , if can sir please be kind enough to explain it also , thank you for the video

DEAR EDMUND OPTICS
WHAT IS THE TABLE NAME? AND WHERE CAN I BUY?
PLEASE REMAIN REPLY

how do we align diffractive grating?

What is the name of that table being used?

hello why you adjusting the red screw in far alignment?

hello I'm not getting fire form 2 or 3 wat do I do or what I'm doing wrong

Please explain how to use Opal Glass Reticle Targets.
