The protective mirror is designed to safeguard the laser system by reflecting and dissipating excess heat and debris. It helps maintain the lifespan and performance of the laser system.The focusing lens plays a crucial role in converging the laser beam to a specific focal point. It enables precise and controlled laser cutting, engraving, or marking applications by concentrating the laser energy at the desired spot.The collimating lens, on the other hand, ensures parallel alignment of the laser beam, transforming a diverging beam into a straight, parallel one. This lens is commonly used in laser diode modules or beam delivery systems, providing a uniform and consistent laser output.At our company, we offer a wide range of laser lenses, including protective mirrors, focusing lenses, and collimating lenses. Our lenses are crafted with high-quality materials and precision manufacturing techniques to ensure optimal performance and durability. Experience enhanced laser performance and accuracy with our top-of-the-line laser lenses.Specification Chart CHECK WHICH PLASMA CONSUMABLES YOU NEED Commonly used protective lens specifications, application occasions and applicable power tableCoating colorSpecificationsQuartz materialApplicationsApplicable powerblue film18*2JGS2handheld welding machine1.5KW18*2JGS1(high power)handheld welding machine3KW20*2JGS2handheld welding machine1.5KW20*2JGS1(high power)handheld welding machine3KW20*3JGS2handheld welding machine2KW20*4JGS2handheld welding machine3KW21.5*2JGS2upper protective mirror 22.35*4JGS2cutting4KW24.9*1.5JGS2upper protective mirror 25.4*4JGS2cutting4KW25.4*5JGS2cutting5KW26.5*5JGS2cutting5KW28*4JGS2cutting4KW28*4JGS1(high power)cutting8KW29.7*4.7JGS2cutting4KW30*1.5JGS2welding1.5KW30*2JGS2welding3KW30*4JGS2welding6KW30*5JGS2cutting5KW30*5JGS1(high power)cutting10KW34*3JGS2cutting3KW34*5JGS2cutting5KW34*5JGS1(high power)cutting12KW36*2JGS2welding3KW36*3JGS2welding4KW36*5JGS2cutting5KW37*7JGS2cutting6KW37*7JGS1(high power)cutting15KW38.1*1.5JGS2upper protective mirror 40*5JGS2cutting5KW40*5JGS1(high power)cutting12KW50*2JGS2welding6KW50*4JGS2cladding10KW50*5JGS2cladding12KW55*1.5JGS2welding6KW55*1.5JGS1(high power)welding12KW134*3JGS2welding6KW134*3JGS1(high power)welding12KWyellow film28*4JGS2cutting4KW30*5JGS2cutting5KW34*5JGS2cutting5KW37*7JGS2cutting6KW40*2JGS2welding6KW40*5JGS2cutting5KW50*2JGS2welding6KW55*1.5JGS2welding6KW List of Laser Lens Models for Raytools Cutting HeadProduct ModelSpecification (mm)Description211LCG0034D22.4*4.1Focusing Protective Lens211LCG0020D24.9*1.5Collimating Protective Lens211LCG0037D27.9*4.1Focusing Protective Lens211LCG0037ED27.9*4.1 NewFocusing Protective Lens211LCG0045D37*1.6Collimating Protective Lens211LCG0068D30*5Focusing Protective Lens110255IAG0004D37*7 6kFocusing Protective Lens211LCG0078D37*7 12kFocusing Protective Lens211LCG0076D38.1*1.6Collimating Protective Lens211LCG0075D38*2Focusing Protective Lens211LCG0069D50*2Focusing Protective Lens211LCG0070D50*2 Full-wave bandFocusing Protective Lens OUR MOQ IS 50 PCSBy the way, we also have brands of plasma accessories, like Hypertherm, Lincoin or Esab consumables .We also can customize products according to our need!The lifespan of Fiber Laser LensThe lifespan of laser cutting and laser welding machine lenses can vary depending on several factors. These factors include the laser power, operating conditions, maintenance practices, and the quality of the lenses themselves.Typically, high-quality lenses used in laser cutting and welding machines have a relatively long lifespan. With proper care and maintenance, they can last for hundreds or even thousands of hours of operation. However, it's important to note that the lenses will gradually degrade over time due to factors such as thermal stress, beam intensity, and debris accumulation.Regular cleaning and inspection of the lenses are essential to prolong their lifespan. Keeping the lenses free from dirt, debris, and residue will help maintain their optical clarity and efficiency. Additionally, following the manufacturer's recommended maintenance procedures and replacing the lenses when necessary will ensure optimal performance and extend their lifespan. Product Description Laser Cutting HeadThe primary function of a laser cutting head is to focus the laser beam to a small spot size and accurately direct it onto the workpiece. It contains optical components, such
