The ANSI Standard Z136.1 recommends a laser safety program for workplaces using class 3B or class 4 lasers. Following are the essential components of a laser safety program:

“By adding a special anti-reflective coating to the cover glass, the light reflection is reduced by more than 75 percent, resulting in a device that’s easier to read in the sun.”

“The problem starts with the cover glass on your device. Light reflects off of the glass which then makes the display appear dark or dull.”

Today's connections are made possible by beams of light constantly bouncing through hair-thin strands of optical fiber. So, how does fiber actually work? Let’s take a look.

A fire can be started when laser beam or reflection of the beam strikes a combustible material such as rubber, plastic, human tissues, paper products, skin treated with acetone and alcohol-based preparations, human hair, and intestinal gases. Fire hazards are of particular concern in oxygen-rich atmospheres when oxygen or when nitrous oxide is being used.

For example, the CSA Standard Z386-20 "Safe Use of Lasers in Health Care" specifies that facilities using lasers shall have a laser safety officer (LSO) and a laser safety committee (LSC) to perform risk assessments, and to ensure that laser safety policies and procedures are developed, implemented and maintained.

The term "laser" is an acronym that stands for "Light Amplification by Stimulated Emission of Radiation". Laser light is a form of non-ionizing radiation. Laser equipment produces and amplifies light that has unique properties that cannot be produced any other way. The light that it produces is monochromatic - it is composed of one single colour at a specific wavelength. Laser radiation can be generated in different parts of the spectrum - ultraviolet (UV), visible light, and infrared (IR).

Protective clothing (gown, cap, mask), gloves, and safety eye wear may be required for working near a laser. Consult manufacturer's operating procedures and check with the laser safety officer to determine the specific needs for personal protective equipment and clothing.

Corning® Gorilla® Glass redefined the toughness and durability of consumer electronics. Gorilla Glass gets its damage resistance from Corning's ion-exchange process. But, how does that work?

Fibrance technology is basically a glass optical fiber that unleashes colorful lighting. Yet, to really understand it, you have to go back to the beginning to learn how it works.

The color of laser light is usually described in terms of the wavelength of the laser radiation. The most common unit used for the wavelength of laser is a nanometer (nm - one billionth of a metre). Light from other sources is made up of combination of colours at various wavelengths.

This process begins with a thin, inorganic film applied to the device’s cover glass. Once in the sun or bright light, the proprietary coating material manipulates incoming light, causing light waves to interfere and cancel each other out.

So, stay tuned. Corning’s pursuit of anti-reflective coatings could soon put an end to the blinding light bouncing off your smartphone.

Essentially, Corning’s anti-reflective solution greatly reduces the intensity and magnitude of light reflecting off a device.

“Corning continues to push the boundary on how glass, along with other companion coatings or technologies, can help solve tough problems for consumers and their devices,” said Petzold.

There are two types of laser hazards: the laser beam hazards and the non-beam hazards. Laser beam hazards include eye and skin burns which are due to laser beam shining on a person's body. Non-beam hazards are associated with the laser equipment or the hazardous substances released from the laser equipment, and fumes emitted from materials exposed to laser beams, including laser-plumes produced during surgical procedures.

Corning produces some of the world's purest glass through a process that, for a while, doesn't seem to involve glass at all. It's called vapor deposition.

Also, rather than dulling colors like some other commercial anti-reflective coatings, Corning's solution enhances color fidelity. This means that your phone’s imagery and text would be sharp and legible even in sunlight.

It is an all-too-common and annoying problem, but one that Corning scientists are tackling head-on with an anti-reflective solution.

The CSA Standard Z305.13-13 (R2020) "Plume scavenging in surgical, diagnostic, therapeutic, and aesthetic settings" also requires that:

The ability of eye wear to filter the laser beam is expressed in terms of optical density. Optical density, type of laser, and visibility required are all important factors in the selection of protective eye wear. Protective eye wear may not provide the same degree of protection for infrared as for visible light and ultraviolet laser beams. Goggles with side shields are preferred because they provide protection against back reflection and side entrance of stray laser beams.

You’re enjoying a sunshiny day when your smartphone rings. The bright light makes your screen nearly invisible, forcing you to squint and strainto figure out who is calling. It is an all-too-common problem, but Corning scientists have come up with an anti-reflective solution.

Corning's proprietary "fusion" process has been a big key to Corning's innovation success over the past two decades. Here's a quick breakdown on how the process works and why it's so important for Corning.

The potential for skin damage depends on the type of laser, power of the laser beam, and the duration of exposure. The type of damage may range from localized reddening to charring and deep incision.

Today's connections are made possible by beams of light constantly bouncing through hair-thin strands of optical fiber. So, how does fiber actually work? Let’s take a look.

The eye is the most vulnerable to injury from a laser beam. The potential for injury depends on the power and wavelength of the laser beam (light). Intense bright visible light makes us blink as a reflex reaction. This closing of the eye provides some degree of protection. However, visible laser light can be so intense that it can do damage faster than a blink of an eye. The invisible infrared laser beam, such as carbon dioxide (CO2) laser beam, does not produce a bright light that would cause the blinking reflex or the pupil to constrict and, therefore, chances of injury are greater compared to visible light beam of equal intensity.

Alignment eye wear: This type of eye wear is used for low power visible laser beams. Alignment eye wear should not be worn during the operation of high power or invisible laser beams. Instead, safety eye wear that provides adequate protection should be worn.

In workplaces where a class 3B or Class 4 laser is used, a laser safety officer (LSO) must be on staff. The laser safety officer must do the following to ensure safe use of lasers.

A wide variety of lasers are used in health care facilities. The type of laser depends on the purpose of use. Lasers can be used as knives or probes and for imaging techniques. For example, laser knives can make cuts that do not bleed. They can be used to smooth skin wrinkles or remove skin moles, cysts, tattoos, spider veins, and so forth. Some commonly used lasers are given in the following table.

Every piece of laser equipment has built-in engineering controls such as protective housing, fail-safe interlocks, master switches, beam stops and attenuators (e.g., light absorbers) to prevent accidental exposure. However, eye protection is needed while using Class 3B or Class 4 type lasers to prevent harmful exposure from reflected and scattered laser beams.

Many lasers use high voltage and high current electrical power. The danger of electrical shock or electrocution arises when an untrained or unauthorized person tries to perform maintenance work without following the proper safety procedures. ANSI Standard Z136.3-2018 outlines electrical safety procedures applicable to laser equipment. Electrical safety requirements include the following:

Customers are beginning to test-drive this thin-film application for their next-generation devices. In the meantime, Corning scientists are developing a version of the anti-reflective, thin-film coating that is tough enough to withstand the harsh handling of mobile devices.

Another property of lasers is they are coherent light sources. This feature means that lasers produce monochromatic light (i.e., with a single or selected wavelength) in which the light “particles” or photons all travel in the same direction. This directionality allows laser beams to be very focused (collimated) so they do not fan out like the light beam of a flashlight. Since the light beam can be contained in a very narrow beam, it has a high radiant power per unit area. These properties enable laser devices to produce powerful laser beams that can cut metal. In health care, lasers are used for cutting, sealing and surgical procedures.

Plastic versus glass lenses: Protective eye glasses typically are available with plastic lenses. Plastic lenses are light weight and can be molded into comfortable shapes. However, care is needed because they can be affected by heat, and/or UV radiation which can darken the lens or decrease its ability to absorb laser energy.

The location of the damage depends on the optical nature of the laser beam. Lasers in the visible light and near infrared range focus on retina. Therefore the injuries produced are retinal burns. The infrared radiation is absorbed in the cornea and may cause corneal damage and loss of vision.
