Laser Out of Focus? Learn How to Use a Crosshair Target in Three Minutes

A laser that doesn't focus correctly can affect work efficiency. This video shows you how to use a crosshair calibration board to quickly solve laser focus problems. It covers preparation of calibration tools, detailed operation procedures, and common pitfalls to avoid. In three minutes, you'll master precise focusing techniques and improve the performance of your equipment!

Why is your laser focus always off?

If your laser is blurry or misaligned, don't immediately jump to the conclusion that your equipment is broken. Most of the time the problem is simply that the equipment needs to be adjusted.The slightest vibration, a speck of dirt on a lens, or even a change in temperature can cause the focus to be lost.At this time, the cross-hair target is your "savior" --it can help you visually adjust the focus with the aid of its clearly marked cross-hairs.

Preparation: Don't forget these small details.

Select the right material for the calibration plate.

Choose a metal or ceramic calibration plate, which will not distort with heat.Don't use acrylic, which is easily warped in high temperatures, and which can result in even larger errors after calibration.

Cleanliness is even more important than you think.

Use a cotton swab dipped in alcohol to clean the surface of the calibration plate. Fingerprints or oil will affect the reflection of the laser.At the same time, it would be a good idea to check the lens for dust, and clean it with a blower.

A step-by-step guide.

Fix the position of the calibration board.

Place the calibration plate flat on the worktable in the center, and press down on the four corners for three seconds to ensure a good fit.If the table is uneven, it is better to lay a few sheets of A4 paper than to press the scanner down with force.

Adjust the calibration mode.

When you turn on the crosshair feature, you will see a red laser beam projected onto the calibration board.The key point: The crosshairs in the software must line up perfectly with the lines on the calibration plate.

The key is making fine adjustments.

The operator first makes coarse adjustments to get the cross hairs roughly aligned, then switches to fine adjustments.It's like tuning a radio. You have to turn it slowly, pausing every 1 / 4 turn to check.

After calibration, don't forget to check.

After you have finished calibrating, don't put your tools away just yet! Use some scraps to test out your cutting.If there is a blurred area, it might be because the calibration board was not level.

Eighty percent of people have fallen into these traps.

• Calibration in strong light (which leads to errors in judgment).

• Using dirty gloves to handle calibration plates (fingerprints are too numerous to be distinguished).

* Turn on the power at its maximum setting (it is suggested that you start at a low setting and gradually work up).

If you follow these steps, you should find that the precision of your focusing is greatly improved.If you still have a problem after repeated adjustments, then perhaps the lens has aged or the guide rail has worn out. It's time to contact the manufacturer for repairs.
