For more information, please see our These 10600nm CO2 laser safety glasses have a strong OD rating thanks to the high-quality polycarbonate lens. Class 3B lasers output power between 5 and 500 milliWatts. Remember, laser cutting means that youre burning material. LSOs (Laser Safety Officer) need to consider working environments, viewing conditions and beam delivery systems when making assessments and determining the correct laser glasses , goggles, barriers, or windows to protect against potentially hazardous laser radiation. Thankfully, Thunder Laser USA has a variety of CO2 laser cutting machines that are manufactured to strict specifications so theyre safe and ready to run upon delivery. Dust particles are naturally very small and therefore have a large surface-area-to-volume ratio. So, make sure you know the wavelength of your laser so you can pick the safest glasses. Because you dont see the laser beam it is easy to forget they are there and try to do something that you otherwise wouldnt, like stare at mirrors or pull out pieces of material while the machine is running. What is more likely (but also far less serious) is damage to the skin (typically hands). To avoid the risk of dust igniting, you must regularly clean the inside of your laser cutter as well as the cutting deck and anywhere else where dust may concentrate. Privacy Policy. These lasers are usually classified as Class-3B or Class-4 lasers, which means that they have sufficient energy to cause permanent damage to the human eye by direct or reflected exposure (and may even cause harm through diffuse exposure in the case of Class-4 lasers). Visible and near-infrared lasers, such as Nd:YAG (see Figure 1 ), can cause retinal damage, while far-infrared lasers, such as CO 2 (see Figure 2 ), and ultraviolet lasers can cause corneal damage. However, always make sure to still check a lasers specific wavelength to be sure. Price and other details may vary based on product size and colour. By ignoring them and operating outside of the manufacturers guidelines, you run the risk of voiding warranties, damaging equipment, and harming yourself or others., A logbook recording what materials have been cut and by whom can be important to safe operation.

The buildup of dust within the laser cutters housing significantly increases the risk of a fire. Fire is an ever-present possibility when working with high-powered lasers. Similarly, as K40 engravers use CO2 lasers, you wouldnt want to use low wavelength goggles as K40 laser safety glasses. If youre wondering how to choose laser safety glasses, here are the key factors to keep in mind: The MOST important factor is ensuring your glasses block the wavelength of the laser youre using. Another benefit is the 60% visible light transmission is higher than that of some other laser safety glasses, meaning you can see slightly clearer when wearing them, while still having a high OD rating. To understand what laser safety glasses to purchase, the most important parameter is your laser's wavelength (or wavelength range). Its vital to take the correct safety measures whenever using a laser cutter, one being to have suitable safety glasses. Some cheap glasses cover the relevant wavelengths, but have low ODs, meaning theyre unsuitable for working with more intense lasers. It goes like this: Dont stare at the laser with your remaining eye. Maximum Permissible Exposure ("MPE") based on several parameters mentioned here. The needed OD is ultimately a function of both the laser being used, and what the laser needs to be reduced to. For optimal CO2 laser safety, controlling exposure to these hazards goes beyond simply closing the lid. If youre working in a darker environment, you can get glasses with higher visible light transmission, or transparency, while still maintaining proper protection. This means you can use a wider range of diode lasers, and they can also be used as fiber laser safety glasses if youre using a low-wavelength fiber laser (fiber lasers generally range from 780 to 2200nm). Keep a fire extinguisher close to the laser, but not to close. Email Us. by looking for the recommended Optical Density (OD), asking your Laser Safety Officer, or feel free to give us a call at 1-866-650-6926 and we can assist.

SCOPE. 2) Level of protection: what protection level is needed is premised on the laser's output. Safe for accidental eye exposure but only because your natural blink reflex is going to limit maximum exposure time under 0.25 seconds. While it can cause damage to an eye if viewed under specific conditions, the risk is low and they are still considered safe under correct usage. A material like wood, however, needs a lower frequency, such as 1kHz, for a nice cut. All our laser glasses meet or exceed the United Stated industry standard ANSI Z136.1, the requirements for use with the appropriate laser systems. As noted above Class 4 lasers are considered dangerous when not properly enclosed because of the damage they can produce to skins and particularly eyes. Fiber and CO2 laser safety eyewear - 800nm to 1100nm, OD 5+ - Universal Fit and can be worn with prescription glasses. Get CO2 filled fire extinguisher instead of dry powder ones so you don't . Lasers rely on generating very high temperatures in the target, to locally char or vaporize the cut zone. Depending on the lasers wavelength, it can also affect the lens and cornea. The laser essentially burns a hole in the macula and causes bleeding of the retina. All laser safety PPE is for unintentional direct and diffused viewing only. When it is cut by a laser, the polymer decomposes to release hydrogen chloride gas. Yes, the laser beams in laser cutters are dangerous. Getting to know your cutter helps you use it as recommended. A common use case for an aiming beam is a laser pointer. Yes, there are a number of laser-cutting safety programs available. They use class 3 lasers, but because they are fully enclosed in a plastic or metal case they are classified as class 1 lasers. Previous article Next article Here are all the details of Voluntari available below. C. ACTION. Description. This causes a dust explosion, which can be remarkably powerful. A standout factor about these 445nm laser safety glasses is that they offer a much higher visible light transmittance than most others, with a very impressive 70%. The above factors impact the price of blue laser safety glasses. Some materials are more likely to catch fire than others. Small flame paired with fume extraction fans which sucks a huge amount of fresh air into the machine will quickly turn into a full-blown fire if not handled immediately. The safety gear that should be worn when using a laser cutter includes: laser safety glasses, a mask or respirator, and thick gloves. Only recently have I caught wind that people wear safety glasses with CO2 lasers. Ferrous materials contain iron, while nonferrous metals are other metals, including alloys, aluminum, titanium and tin. I had a Glowforge Basic and now an Omtech Polar. For example, glasses with wider wavelengths and higher visible light transmissions can sometimes cost double the price of glasses with narrow wavelengths and lower VLT.
