Do these mirrors work with the 50w co2 laser? i see one reviewer said they used them? or do i need the mo ones?

Yes, it is used for CO2 laser engraver ,co2 cutting ,. A laser tube requires 1 focusing lens, 3 reflective lenses Silicon Mirror or Mo Mirror can also meet co2 engraver, the following is their advantages and disadvantages. 1. The material of the silicon reflective lens is silicon. After polishing the silicon, it cannot be used. It needs to be plated-layer gold film, which is expensive, so the cost of silicon reflective lens is high and the price is high. It has the advantages of high reflectivity, light quality, wipe -resistant, strong antioxidant, durable. Can withstand high power 60 ~ 300W. 2. Molybdenum metal reflective mirror is directly polished by metal molybdenum into mirror surface. There is no coating layer on the surface, scrubbing, and a long life. The surface of the molybdenum is high, the melting point is high, the chemical properties are stable and high -temperature, and the corrosion resistance. Molybdenum reflection The mirror can be applied to a harsh working environment, with a applicable power below 100W. In general, molybdenum reflexivity is not as good as silicon, and silicon reflectivity is higher. Molybdenum anti -abrasion is more abrasion, and the cost is relatively cheaper than silicon. The use conditions for silicon reflective lenses are strict than the use conditions of molybdenum reflective lenses, and they are more particular about guarantee. High -power cut thick plates are recommended to choose silicon.

I have a mophorn laser engraver 80w laser cutter co2. which mirrors so i purchase for backup?

Hi, This is link for Si mirrors. Please choose matching diameter for your laser machine. Normally it uses mirrors with D25mm.

Do you offer the Silicon mirror without the gold coating? Also what is the surface roughness (Ra) in nanometers?

Hello, we are selling molybdenum inverse and silicon inverse. 1. The material of the silicon reflective lens is silicon, which cannot be used after polishing the silicon. It needs to be plated with a gold film, which is expensive, so the cost and price of the silicon reflective lens are high. It has the advantages of high reflectivity, light weight, scratch resistance, strong oxidation resistance and durability. Can withstand higher power 60~300W. 2. The molybdenum metal mirror is directly polished to a mirror surface from metal molybdenum, and the surface has no coating layer, which is resistant to scrubbing and has a long life. Molybdenum has high surface strength, high melting point, stable chemical properties, high temperature resistance and corrosion resistance. Molybdenum reflection The mirror can be used in harsh working environments, and the applicable power is below 100W. In general, molybdenum is less reflective than silicon, which is more reflective. Molybdenum mirrors are more wear-resistant and cheaper than silicon mirrors. The use conditions of silicon mirrors are stricter than those of molybdenum mirrors, and they are more particular about sample preservation. It is recommended to choose silicon reverse for high power cutting of thick plates. 3: What is Nano Surface Roughness? Answer: The surface roughness comparison is as follows: 1.6 No traces of processing can be seen 0.8 The direction of removal of machining marks can be recognized 0.4 The direction of machining marks can be slightly recognized 0.1 dark glossy side 0.05 bright glossy finish 0.025 Specular

Will this work on a Mira 7 ?

In general, a laser tube requires three reflective mirrors to work. Material: Gold-Plated Silicon; Compatible power: 60W-300W Cloudary Si mirrors are compatible with your laser tube up to 300W. Silicon mirrors are the most used mirrors at present and have good optical thermal properties. The material of silicon reflector lens is silicon, after polishing silicon can not be used, need to plating - layer of gold film, expensive, so lead to silicon reflector lens high cost, high price. It has the advantages of high reflectivity, light weight, wipe resistance, strong resistance to oxidation, durability and so on. It can withstand higher power of 60~300W.
