Feature:1. The laser reflective lens is widely used in laser processing, which is an indispensable accessory for laser engraving machines, laser marking machines, and laser cutting machines2. The substrate of the silicon reflective lens is silicon, which has good optical and thermal properties3. After the reflective film is coated on the surface of the silicon, its reflectivity can be greatly improved, about 99%, and the loss of light caused by reflection is almost avoided4. The product have good optical thermal properties, high reflectivity, goldplated film with scratch resistance5. Laser reflective mirror can adapt to work in harsh environments with long service lifeSpecification:Item Type: Laser Lens SetMaterial: SiliconCoating Band: 10.6mDiameter Tolerance: +0/-0.1mmThickness Tolerance: 0.1mmSurface Type: /2per1in DiaSurface Quality: 40-20Diameter: Approx. 25mm / 1inThickness: Approx. 3mm / 0.1inApplicable Power: 60W-300W (high power)Scope of Application: Laser reflective lens is widely used in laser processing and is an indispensable accessory for laser engraving machine, laser marking machine and laser cutting machine.Package List:3 x Reflective MirrorNote:1. Install in the laser head with the concave surface facing down and the convex surface facing up.2. Depending on the specific usage, wipe 1 or 2 times a day: use a cotton swab or lens cleaning paper, gently rotate the wipe from the inside to the outside, and then process after evaporates.3. The laser hits the edge of the lens and the junction of the lens barrel, which is easy to crack.
