Laser lens are important accessories for laser engraving machines and play an important role in the adjustment of the optical path. In the market, the price of laser lens varies greatly, and the laser lens has a focusing laser lens and a reflective laser mirror. First, let's talk about the price difference of focusing laser lens.
The price difference of focusing laser lens mainly comes from the following aspects: 1. Differences in materials: The focusing laser lens material has the difference between domestic pvd and imported cvd. The difference between the two materials is very large, the domestic pvd price is low, the material is turbid, and the impurity content is high. These have low light transmission and are suitable for low power co2 laser tube. Imported cvd is expensive, material is transparent, low impurity content, high light transmittance, suitable for high power co2 laser tube. 2, the difference of polishing methods: the polishing method of focusing laser lens has low throwing, that is, classical polishing and high-speed throwing, the difference between the two is relatively large, classical polishing does not damage the material crystal of the focusing laser lens, the spot is fine, but the efficiency is low, the labor is expensive. Compared with the classical throw, the high-speed throwing efficiency is high and the labor is cheap, but the crystal of the focusing laser lens material is damaged, the grain is rough, and the spot is thick. 3, then the difference in coating: the surface of the focusing laser lens is gold-plated, the coating process is very different, the focusing laser lens withstand power is different, there are three kinds of 300w co2 laser tube and 600w co2 laser tube above, which leads to different coating costs. The above three cases are the reasons for the price difference of the focusing laser lens.
Let us talk about the price difference of the reflective laser mirror: the reflective laser mirror has the silicon reflective laser mirror and the molybdenum reflective laser mirror. The two materials and the production process have different prices. Here, we mainly talk about the price difference of silicon reflective laser mirror: the substrate of silicon reflective laser mirror is silicon, which is the domestic production of materials, there is no domestic and imported points. The price difference of the silicon reflective laser mirror is mainly in the two aspects of polishing and coating. The polishing determines the flatness of the silicon reflective laser mirror, and the flatness of the surface is high and artificially more expensive. The coating of silicon reflective laser mirror and the coating of focusing laser mirror are similar to those of 300w co2 laser tube and 600w co2 laser tube. Some manufacturers of silicon reflective laser mirror have less than 300w co2 laser tube coating requirements, and can only achieve 200w co2 laser tube.
The use requirements, the price is naturally lower, please customers to choose the product according to their own requirements, of course, the coating requirements of silicon reflective laser mirror are higher, do not have the quality problem of stripping.
