Ansi Z136 And En 207 Standards
Indelibly printed on the laser safety glasses are two sets of numbers: Optical Density and LB-Rating, which are both used to indicate the level of protection provided for specific wavelength ranges. The OD numbers indelibly printed on the laser safety glasses can be used to determine if the glasses meet the ANSI Z136 standards of laser safety protection for a given laser product. In addition, the OD can be used to calculate the transmission of light through the laser safety glasses.
The European EN 207 standard for laser safety glasses requires that the protective eyewear be labeled with the CE mark and that the LB-Rating specifications are indelibly printed on the lens. In addition, the lenses and frames must be able to provide the stated level of protection for 10 seconds or 100 pulses depending on the mode of the laser. The LB-Rating is composed of 3 components: a wavelength range, a laser mode designation, and a scale number. The wavelength range engraved on the laser safety glasses is given in nm and is extremely important since the level of protection provided by the laser safety glasses is wavelength dependent. The laser mode designation is based on the duration of laser pulse emitted by the laser.

Visible Light Transmission In Relations To Laser Safety Glasses
Great absorption effect
- Most eyewear offer protection from specific wavelengths, and allow other wavelengths in the visible light spectrum to pass through for unhindered vision.
- Visible Light Transmission is the amount of light that can pass through the lens of a pair of glass. With increase in VLT, more color passes through the lens.

Mention: If You Value Your Eyes These Things Are The Real Deal
- When conducting high-energy laser experiments and research, not only must wear protective glasses, but also no reflective objects on the whole body. Such as watches.
- Laser protective glasses are mainly used to prevent laser spots and stray light. Even if you wear laser protective glasses, people cannot look directly at the laser.
- Please do not look directly at the laser, otherwise it will cause irreversible and permanent eye damage.

Yag Laser Safety Glasses
YAG Laser Glasses | Yag Laser Goggles | 1064nm Laser Glasses
To protect you and your staff against laser eye injuries, consider the Yag Laser Glasses when working around your Yag laser. Since accidental laser exposure can lead to irreversible eye damage, it is important to properly wear your laser safety glasses. Appropriately matching the operating wavelength frequency to the laser safety glasses is crucial, as well as knowing of the type of laser you are working around. Universal Medical offers the Yag laser glasses in a series of wavelength frequencies, providing great protection against harmful laser radiation.
While laser procedures are performed, it is a requirement and essential safety component to wear laser safety glasses in medical, surgical, dental, laboratory or cosmetic facilities. These 1064nm Laser Glasses will keep your organization in compliance with ANSI Z136.3 standards, for those working with high power Class 3B and Class 4 lasers and laser systems in health care facilities. Polycarbonate is the lens material found in Yag laser glasses.
Biological Impacts In Relation Laser Safety
- Laser protective glasses, the purpose is to prevent laser.
- There are usually two kinds of lasers, the lasers between 400nm-780nm is visible light, the light can be seen. Lasers above 780nm are infrared light and are usually invisible.
- High-energy laser, the most common is optical 1064nm 10600nm, invisible to human eyes. For example, suppose that the light hits the human eye, and the human eye does not respond at all, and does not know timely prevent it by closing the eyes. If the laser energy is slightly stronger at this time, it may cause blindness.
- Mention: If you value your eyes, these things are the real deal.

European Norm For The Selection Of Laser Safety Glasses
|Please refer to the official EN 207 standard that can be purchased from BSI.
There are two ways to use the table above: start with the scale number and calculate the maximum safe power density or start with a power density and calculate the minimum safe scale number. This is demonstrated by the two examples below.
Example 1: The LG3 laser safety glasses have an LB-Rating line that reads “180-315 D LB7 + IR LB4”. So if the LG3 glasses are being used with a 10 µs pulsed 280 nm light source the table above can be referenced to find that, E=3x10n+1 J/m2, where in this example the scale number is LB4 so n=4. As a result, when the LG3 laser safety glasses are being used in this situation the maximum power density of the light source should not exceed 3×105 J/m2.
Example2: A CW Krypton Ion laser lasing at 647.1 nm has a maximum power density of 2.2×104 W/m2. Using the table above, the scale number can be calculated using LBn=log10-1, which results in a rounded up scale number of 4. The LG4 laser safety glasses meet the safety specifications of the European EN 207 standard for this example.

Laservision Laser Safety Eyewear
The general term laser light characterizes the electromagnetic spectrum between 150nm and 1mm. More precisely it covers the whole range from hard UV up to the infrared light. Due to state-of-the-art technologies the emitted optical power from one laser source can reach multiple kW . Due to its physical properties laser light can be focused to power densities that are high enough to melt or evaporate tissue, metal or ceramics. In the medical field laser radiation is used to remove tattoos or to cut human tissue.Therefore a high potential risk is the accidental illumination of the user. Especially the eyes are much more sensitive to light and therefore they are at increased risk. In fact, it is possible to cause irreversible ocular injury with just one glance of a direct or reflected laser beam even at lower power output levels. Therefore the legislator prescribes the use of laser safety eyewear and/or, if necessary, additional protection arrangements when working with certain laser power. Furthermore the European laser safety standards EN207/EN208 require an EC-type examination by an independent Notified Body who certifies the laser safety eyewear with LB-laser safety ratings.Laser safety eyewear, which is based on coated or absorbing glasses and plastics, is one of the key products of laservisions laser safety portfolio. For this reason laservision is able to offer a perfect solution for all laser applications.

Note: The values in this table are rounded down to provide conservative beam areas.
When working with fiber optics, light emitted directly from the endface of a fiber is diverging. Thus, the power density is decreasing as the beam spreads and the danger of damage to the eye decreases. The table to the left lists the beam area created by light exiting a fiber for fibers with numerical apertures between 0.10 and 0.50. If you know the total power emitted from the fiber, you can calculate the power density at 25.4 mm from the fiber tip. This power density will allow you to determine the safe fiber-tip viewing distances.

Laser Safety And Classification
Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina.
