Let’s take a closer look at electrically conductive plastics and explore how we utilise Indium Tin Oxide (ITO) coating technology to unlock their potential.

Anti-fingerprint coatings create a barrier against everyday marks, ensuring that your devices, and other surfaces, remain pristine and clear.

The first choice you need to make it whether to go for a Fixed ND Filter or a Variable ND Filter. A variable ND filter offers more options, which is great if you’re shooting in changing light conditions, or just starting out with ND filters. A fixed ND provides a specific light reduction and works better with telephoto and wide-angle lenses. The next choice you need to make is the level of light reduction you want. The higher the ND number, the more light it blocks from reaching your camera sensor.

Partnering with a local Australian archival framer, Urth Art prints are framed with sustainably sourced timber to display the artwork, without damaging the environment. And to bring the gallery experience home, Urth Art prints are protected by art-grade acrylic glazing that prevents fading and discolouration.

Urth Neutral Density Filters (ND Filters) cut out a fixed amount of light unlocking more creative possibilities with your photography and filmmaking. ND Filters allow you to control the amount of light entering your camera so you can create stronger depth-of-field and motion blur effects.

As the name suggests, anti reflective (AR) coatings are optical coatings applied to the surfaces of optical elements, lenses, etc. to reduce reflection. Improving the efficiency of typical imaging systems (reduced reflections means reduced loss of light), AR coatings also improve complex systems’ (microscopes, telescopes, etc.) contrast of images by eliminating stray light, which is particularly important for planetary astronomy.

Urth Neutral Density Filters (ND Filters) cut the amount of light entering your camera to unlock motion blur and depth-of-field effects. By filtering out light, Urth ND filters allow you to open up your aperture for a shallower depth of field even in bright light. Or you can compensate for the lower ... Read more Read less

Of particular benefit is the large size of the parts that Diamond Coatings can apply AR coatings to. We can anti-reflect parts up to 1m x 1m, which is much larger than typical for the coating industry.

The bold style of Maui Jim's rectangular frames with neutral grey lenses offers the highest available light reduction for the richest colour and clarity.

The first, and simplest, type of AR coating was discovered in 1886 by British Physicist and Nobel Prize Winner (physics, 1904) John William Strutt, 3rd Baron Rayleigh (Lord Rayleigh). Upon testing some old, tarnished glass pieces (chemical reactions between the environment and the optical glass of his time tended to cause surface tarnishing on glass as it aged), Lord Raleigh found that – to his surprise – these tarnished pieces transmitted more light than clean, new pieces.

Consisting of thin transparent film structures, many AR coatings have layers of alternating contrasting refractive indexes. The thickness of layers is selected to generate destructive interference within beams reflected from interfaces, as well as constructive interference within corresponding transmitted beams. Making the structure’s performance alter with incident angles and wavelengths, this frequently causes colour effects to appear at oblique angles.

While CPL filters polarize light to remove reflections and increase colour saturation, ND filters reduce the amount of light that makes it through to your camera’s sensor, which opens up opportunities to experiment with depth of field and motion blur effects even in bright light.

The lens first devised by Augustin Fresnel (pronounced fraynel) (1788-1827) is a beehive shape of concentric annular sections that cast parallel beams of light.

The surface tarnish replaced the interface between air and glass with two new, air-tarnish and tarnish-glass interfaces. Due to the tarnish having a refractive index between glass and air, these two interfaces each exhibited less reflection than a clean air-glass interface. The total of these two interfaces’ reflections is, in fact, less than the reflection of a ‘naked’ interface between air and glass, which can be calculated via the Fresnel Equations.

Urth Neutral Density Filters (ND Filters) cut the amount of light entering your camera to unlock motion blur and depth-of-field effects. By filtering out light, Urth ND filters allow you to open up your aperture for a shallower depth of field even in bright light. Or you can compensate for the lower light by slowing your shutter speed and creating motion blur effects without overexposing your photographs. ND filters are a crucial tool for filmmakers too as they allow you to film in bright and harsh light without overexposing or pushing your exposure settings too far. Urth ND filters give you greater creative control when there is excessive light like you’ll experience in outdoor photography and filmmaking. Urth fixed ND filters block a set amount of light, while Urth Variable NDs have a rotating element that adjusts the amount of light blocked depending on what you need. Each ND filter plants 1 tree so future generations can enjoy nature as much as we do now. All our circular filters come with a protective travel tin case, a recycled cleaning cloth, and recycled plastic-free packaging. Read more Read less

Development of AR coatings continued over the coming decades and in 2002, Diamond Coatings established its first ITO and AR Coating manufacturing plant in the Midlands, UK. Operations were expanded to Arizona, USA in 2016 and today, Diamond Coatings is a leading supplier of AR & ITO coatings to world-wide industries including:

Fixed ND filters block a fixed f-stop of light from entering your camera. Variable ND filters provide more flexibility and have a range of f-stops you can block by rotating the outer element. If you’re starting out with ND filters, we recommend a Variable ND so you have more flexibility while you’re learning how to shoot with an ND. If the light is likely to change often, a Variable ND saves you changing between fixed NDs each time.

Before going into the history of AR coatings, allow us to begin by looking at what exactly an anti reflective coating is…

Although it is necessary to specify wavelength ranges when designing/ordering anti reflective coatings, good performances can frequently be achieved for comparatively wide frequency ranges. Choices offered usually include IR (infra-red), visible and UV (ultra-violet). The question is, where did it all begin?
