In the presence of multiple asymmetric optics with the same lmax value and same beam opening range, it will be necessary to distinguish them by adding the numeric value of the beam opening at the end.

By convention, we consider the beam opening of plane α. Multiple optics within the same range of opening will be distinguished by inserting the numerical value of the beam opening at the end.

EXAMPLE Elliptical optic code: E α x β where: E = Elliptical α = Opening of the light beam on plane α expressed in degrees β = Opening of the light beam on plane β expressed in degrees

For road optics, PERFORMANCE iN LIGHTING identifies the optics that have a very broad beam spread on the β plane (usually greater than 120°), with the point of maximum emission on one of the adjacent planes to the latter, up to a maximum of 45°.

The diagram below identifies the data that will be contained in subsequent pages, regarding the opening angle of the beam. IMAX = maximum luminous intensity, i.e. the maximum intensity of the emitted light beam.

PERFORMANCE iN LIGHTING identifies those optics that generate a luminous emission with a symmetry of revolution about the A axis as circular optics. The opening angle of the beam is generally constant in all planes. The reflectors generating these optics generally have a circular opening. EXAMPLE Circular optic code: C/xx where: C = Circular xx = the abbreviated name of the opening angle For example: C/I - C/M - C/IW - C/MW -C/EW Multiple optics within the same range of opening will be distinguished by inserting the numerical value of the beam opening at the end. For example: C/IW46 - C/IW50 Circular optic name Type of optic Acronyms Opening angle plane α C I 0° ÷ 20° M 21° ÷ 45° IW 46° ÷ 60° MW 61° ÷ 75° EW > 75° Mandatory indications Additional indications Type of opening Opening angle α C1 30° ÷ 45° C2 25° ÷ 30° C3 20° ÷ 25° C4 15° ÷ 20° C5 10° ÷ 15° C6 0° ÷ 10°

For optics for pedestrian crossings PERFORMANCE iN LIGHTING identifies those optics for lighting in the direction of their flow. They feature asymmetrical emission both on the α plane and on the β plane. EXAMPLE Acronym of optics for pedestrian crossings: Z/R where: Z = zebra (pedestrian crossing) R = right (for countries where driving is on the right)

PERFORMANCE iN LIGHTING elliptical optics are circular but differ from roto-symmetrical circular optics because the opening of the light beam on planes α and β is symmetric, but differs greatly between the two. The light distribution is highly elliptical.

For PERFORMANCE iN LIGHTING, symmetric optics are ones with symmetric emission in relation to planes α and β. The symmetry between the two planes may be either identical (in this case we are dealing with optics with square light distribution) or different (optics with rectangular light distribution). EXAMPLE Symmetric optic code: S/xx where: S = Symmetric xx = the abbreviated name of the opening angle For example: S/I - S/M - S/W - S/EW By convention, we consider the beam opening of plane α. Multiple optics within the same range of opening will be distinguished by inserting the numerical value of the beam opening at the end. For example: S/W50 - S/W60 Symmetric optic name Type of optic Acronyms Opening angle plane α S I 0° ÷ 20° M 21° ÷ 45° W 46° ÷ 75° EW > 75° Mandatory indications Additional indications Type of opening Description S1S2 Includes all symmetrical optics from Narrow to Wide for Power LED SNSMSW Includes all symmetrical optics from Narrow to Wide for COB ARRAY Free distribution MEDIUM Medium beam diffuser OPALMICRO Wide beam diffusers SYMM Symmetrical optic

Anti-reflective coating, also known as anti-glare or AR coating, is a layer added to eyeglasses to make them more efficient. The coating can help improve vision while also reducing eyestrain and enhancing appearance.

Opticsdefinition

You can get an AR coating that can help repel both oil and water. This will keep dirt from sticking to your glasses. Your glasses will be much cleaner, helping enhance your vision. Anti-reflective coating can be applied to all types of eyewear lenses. There are different types of coatings available, and you can choose the AR coating that will work best for you.

AR coating helps you to see much better through your glasses. The coating allows more light to go through the glass lens, enhancing visual clarity. The coating eliminates glare, allowing clear vision, especially when working, driving, and in the classroom. The coating is especially effective when used with high-index lenses. These lenses reflect light better than regular plastic lenses.

PERFORMANCE iN LIGHTING asymmetric optics generally have asymmetric light distribution on plane α with a point of maximum concentration. The axis passing through the point of maximum concentration and the point marked by the axis of the lamp is called the Imax axis. The light distribution on plane β, on the other hand, may be symmetric or asymmetric. An asymmetric optic may be symmetric in relation to one plane only.

Eliminating the harsh reflections from your glass lenses will allow people to see you well. The AR coating removes the glare that can cause people not to see your eyes. The glasses look virtually invisible, so your eyes and facial expressions appear more clearly.

PERFORMANCE iN LIGHTING identifies those optics that generate a luminous emission with a symmetry of revolution about the A axis as circular optics. The opening angle of the beam is generally constant in all planes. The reflectors generating these optics generally have a circular opening.

The coating eliminates reflections from the surface of the eyeglass lenses. Eliminating the reflections allows the passage of more light through the lenses, helping optimize visual acuity. There are several benefits to having an anti-reflective coating on your eyeglasses.

EXAMPLE Asymmetric optic code: Ayy/xx where A = Asymmetric yy = numeric value of the Imax angle. The Imax angle is the angle between axis A and the lmax axis.

Having an anti-reflective coating on your glasses will help enhance comfort. The benefit of less glare and sharper vision means you will enjoy more comfort when using your computer. You can reduce exposure to blue light.

Grazing reflector optics stand out for their luminous emission that is typically parallel (grazing) to the installation surface (wall or ground). These optics are primarily used for architectural lighting with the purpose of designing patterns of light and they rarely have a functional use. A fundamental characteristic is the value of the α angle that identifies the value of the light beam aperture measured on the installation surface.

AR coating can help protect your eyes from harmful UV rays. UV protection is often added to the back of the lenses to protect the eyes from the damaging effects of the sun. The coating helps protect against the rays reflected off surfaces such as windows and sidewalks.
