The items arrived quick and where well packed. The fiber optics are high quality. The team at Evan Designs where very helpful and friendly with my questions and gave such excellent support. I will definately order from them again.

Light that has been polarized is useful because it enables the user to be selective over what part of the electromagnetic spectrum is used (whether for photography, night-vision, coloured lighting or analytical measurement). Of course, this filtering of light can offer the user a finer level of detail for their application, similarly to a sharp knife or a small paint brush.

Electric polarization

Some light waves will be parallel to these wires and those electrons will move along the wires instead of passing through to the other side of the filter. Any electrons that are not angled at the same plane as the wires (perpendicular) do not collide and are therefore free to move to the other side.

I ordered a couple of lengths of fiber optics for a trial. The desired strands came in the mail in good time, undamaged, and were just what I was looking for.

Linear polarization

What we generally refer to as “light” is more correctly known as ‘electromagnetic radiation’ (often abbreviated as EM radiation). The the main characteristics of electromagnetic radiation are its frequency and wavelength (λ). We broadly classify frequency into types of EM radiation, such as radio waves, microwaves, terahertz, infrared, visible light, ultraviolet, X-rays and gamma rays. In this sequence, radio waves are radiation with the lowest frequency (and largest wavelength) and gamma rays have the highest frequency (and shortest wavelength).

Evan Designs is an awesome company with great products! I've never had an issue with anything I've purchased from them and the customer service is above and beyond!

Polarization

Many interactions of light with matter depend on its polarization. For example, at a reflective interface, components of light whose polarizations are oriented perpendicular to the plane of incidence are reflected more strongly than those oriented parallel to it. At one angle of incidence in particular – Brewster’s Angle – the reflected ray is completely polarized perpendicular to the plane of incidence.

The items arrived very quickly and the packaging was greatc! The quality of the fiber is top notch and will be buying again thanks!

Here is a great example of a use for fiber optic sent to us by one of our customers. You can see the numbers are nicely outlined and illuminated without being too intensely bright.

2020510 — I need an idea of how to make a homogenously lit circle around a circular capacitive switch. The LED should be at least 4-6mm apart from the capacitive pad.

EM radiation has an electric and magnetic field component which oscillates in phase perpendicular to each other and to the direction in which the radiation propagates. These two oscillating fields are often visualised as in the diagram above and are continually self-propagating.

Our fiber optic is sold by the foot, 0.75 cents per foot. Choose your size and add the number of Feet you need to cart.  We measure by the foot but we sell in whole pieces, so for example if you get 3 feet or 6 feet you will get a full sized piece it will not be cut.

Controlling reflections is an important application of polarizers. If the specific interactions with the surface are of interest, then the polarizer can be oriented parallel to select only the reflected rays; if the reflections are an unwanted source of measurement noise, the polarizer can be oriented to reduce them.

Fiber Optic is a great choice for bringing light into challenging to reach spaces. The optic strands are fairly flexible and they carry the LED source light out to the end of the strand.  They are great for lighting up elements that may be hard to fit LEDs into.

Unpolarizedlight

The orientation of the electric field plane is known as the “polarization direction” (E). This can be broken down into three basic categories:

Wire Grid Polarizers are included in the Specac polarizer product range. It consists of an array of fine parallel conductive wires placed perpendicular to the incident beam, with the spacing of the wires being smaller than the wavelength of the light being filtered.

For waves with their electric fields perpendicular to the wires, the electrons cannot move far across the wires (remember, the diameter of the wires are much smaller than the wavelength of light). So the perpendicular light passes through un-blocked (save for very small amounts).

Great prices and service as usual. Have been purchasing LEDs in the past, so when I say that they had the fiber optic I was looking for - it was a no brainer.

Specac provide a range of infrared wire grid polarizers for use in analytical testing across the mid-and-far-infrared spectrum of light. Some of these are compatible with our spectrometer accessories, allowing the user to mount a polarizing filter directly into an accessory or sample cell, further refining their analysis.

In many spectroscopic and photonics applications, it is desirable to work with light that has been polarized in a particular direction. In this article we explore what polarization is, and how it may be obtained from an unpolarized light source.

We have a new way to connect fiber optic. Choose 3mm connector for 3mm LEDs.  Choose 5mm connector for 5mm LEDs  It can hold one piece, or several pieces of fiber optics. The black color is very good at cutting down the side light from the LEDs. This will hold onto your LED very firmly.
