How to choose the field lens of the main components of the laser marking machine

We all know that laser marking machine is mainly composed of laser, cabinet, optical path, field lens, lens, marking software and computer. When we buy laser marking machine, we usually focus on the choice of laser In fact, the field lens, another main component, is also equally important, and has a greater impact on the marking effect.

The field lens is a key component of the laser marking machine. The types of field lenses used in marking different objects are also different. The common field lens specifications are 50 *50mm, 110*110mm, 160*160mm, 220*220mm, 300*300mm, 500*500mm, etc. Using different specifications of field lenses is equivalent to choosing different focal lengths, mainly depending on the size of the marking object, the marking depth, the degree of fineness, the size of the marking format and the overall matching of the equipment.

For laser marking airport mirror size and lens focal length, some customers said, I want to buy a field lens with a large marking size, so that I can mark products of different sizes and apply The field is wider, in case the development of new products will have to add equipment in the future. If the size of the field lens is increased, the focus spot will increase, and the distortion will also increase. The focal length of the field lens lens is the working distance from the bright surface of the lens to the product. also increase. These changes will cause the marking effect to be not detailed enough, the consumption of laser energy, and there is no small-format lens to mark clearly.

Regarding the wavelength, it must be matched with the laser marking machine, but many customers do not know what wavelength their laser marking machine is. Generally, non-metallic machines are generally 10.6 microns, that is, the field lens of CO2; while semiconductor machines, that is, machines that mainly play metal, have a wavelength of 1064 nm; while laser engraving machines, green laser machines, have a field lens of 532 nm wavelength. of.

Under the conditions of the same size, due to the different design and processing capabilities of the major field lens manufacturers, there will be field lenses of the same size, and the focal length will be different. In the case of the same format, the shorter the focal length, the better. However, due to the design process, it is impossible to be infinitely short, so we just ask for one that is as short as possible, because the field lens with a short focal length is deep and the lines are thin.
