Anyone who has used a laser marking machine or has been in contact with a laser marking machine knows that when using this equipment, the problem of correctly adjusting the focal plane is involved. Equipment manufacturers will emphasize the importance of focal length when equipment installation training and sample adjustment. Laser laser engraving on the correct focal length surface is a key factor for the equipment to perform its performance properly. Many equipment users directly how to debug laser marking equipment correctly. Confusion and misunderstanding of the focal length. Today, this article roughly summarizes some conventional laser marking machine focal length debugging methods.
First, before understanding the correct debugging method, we now popularize and understand the correct definition of the focal length here:
Focal length, also known as focal length, is a measure of the concentration or divergence of light in an optical system, and refers to the distance from the center of the lens to the focal point of the light.
In laser marking equipment, after the laser is shaped by the laser, it will be irradiated to the focusing field lens with a parallel beam. Most conventional laser marking equipment uses a convex lens. The convex lens is optically refracted to focus the parallel light beam to a focal point. Forms a focal plane. The vertical distance from the focal point of the convex lens to the focal plane is what we call the focal length. We generally use F = how much to represent its focal length.
