S = skip. HPOL light vibrate sideways, and skips off the surface with almost zero penetration. Think of a pencil held sideways, then thrown toward the surface. It hits the surface with the pencil sideways, and reflects the sideways pencil away.

This 8oz can of compressed air contains a safe propellant, Difluoroethane, which is ideal for cleaning sensitive surfaces. Designed for use in situations where the surface to be cleaned reacts negatively to traditional liquid based cleansers or where the space to be cleaned is difficult to access. Applications include clearing dust and other debris from computer equipment, keyboards, circuit boards, non-energized machinery, switches, auto detailing and any number of other applications. Propellant is delivered with enough force to clean the surface without damaging surrounding equipment. Completely safe for the ozone and made in the USA. Contains a bitterant to discourage inhalant abuse.

P = penetrate. Think of a sewing machine needle, going up and down in a vertical direction, penetrating cloth. That's what the E field is doing to the optical surface.

From the figure below, (1) goes in the Z direction, but the electric field oscillates in the Y direction, thus becoming Y-polarized light (linearly polarized light in the Y direction).

s-polarization vsppolarization

The plane formed by the incident light vector and the boundary normal vector is called the incident plane. When the electric field oscillates perpendicular to the incident surface, it is defined as s-polarized light or TE-polarized light. When the electric field oscillates parallel to the plane of incidence, it is defined as p-polarized light or TM polarized light. S is a vertical word in German with the acronym Senkrecht. p stands for parallel.

P polarised lightapp

(2) It advances in the Z direction, but because the electric field oscillates in the X direction, it becomes X-polarized light (linearly polarized light in the X direction).

Hey yuan, Iam need to see how the polarization effects the interference. how can i set a polarizer such that only S-polarised beam is transmitted. I tried to define ideal2 coating on a cylinder and placed on beam path. But i cant see the effect of places polariser. Could you please help with this regards?

Swiffer Dusters TRAP + LOCK dust & up to 95% of allergens (Common inanimate allergens from cat and dog dander & dust mite matter). Use Swiffer Dusters for cleaning wherever dust shows up, including fan blades, blinds, car interior, keyboard vents, bookcases, and more. They are made with specially coated fibers that grab onto dust & don't let go.

Plane polarizedlight

When linearly polarized in a specific direction, the light source can be rotated by an angle, thus changing the polarization direction of the resulting light.

If you want to polarize light in a specific direction, you can model it by setting the polarization state of the light source + reference axis + rotation of the light source.

Linearly polarizedlight

Swiffer Heavy Duty Dusters TRAP + LOCK up to 3x more ( vs. feather duster) dust & allergens ( common inanimate allergens from cat and dog dander & dust mite matter). 360 degrees of specially coated fibers grab onto dust & don't let go. They are uniquely designed to Trap + Lock dust from every direction.

In Zemax, the local coordinates used to define the polarization state of the light source are Jx (the energy corresponding to the S component) and Jy (the energy that defines the P component).

Circular polarization

Similarly, if the light source is polarized in the Y direction, you can choose an X-axis reference so that there is no component in the Ex direction.

P = penetrate. Think of a sewing machine needle, going up and down in a vertical direction, penetrating cloth. That's what the E field is doing to the optical surface.

P polarised lightmeaning

If you want to set it to X-direction polarization as a prerequisite for light propagation in the Z direction, you need to choose a Y-axis reference.
