Edmund Optics, a leading global manufacturer and supplier of optical components, has expanded its extensive inventory by partnering with Meta Materials Inc. (META ) to release META holoOPTIX Notch Filters, a new product line that consists of large, flexible holographic notch filters.

Fused silica and fused quartz are amongst some of the most popular optical materials. However, there can be some confusion between the two due to their similar properties, to the components, they are used for. In this article, we’ll look at the differences and similarities between fused quartz and fused silica.

The degree to which fused quartz glass contains impurities and/or naturally occurring flaws will be governed by the quality of the quartz sourced for its manufacture. Although fused quartz glass contains more flaws than fused silica, it should be noted that these flaws will not be visible to the naked eye, and only impact upon the viability of fused quartz as a material for applications with extremely high optical requirements.

Unlike fused silica, fused quartz is made from naturally occurring material in the form of crystalline quartz or silica grains. Fused quartz glass is manufactured by melting the natural quartz crystals, with the results containing more impurities than fused silica.

Expansion to Florida With the expansion of facilities to Florida, Edmund Optics has now opened a 34,000 sq. ft. Laser Optics Center, creating possibilities for targeting customers in the region with specialized high-power laser systems.

Expert Leadership Under the leadership of Robert Edmund as the Chair and CEO, Edmund Optics has a solid direction and vision, providing a stable and innovative environment for customers interested in cutting-edge optical technologies.

Fused silica is a synthetic material. It is a non-crystalline silica glass and is made from either pure silicon gas or non-crystalline silica sand. Fused silica is the purest form of glass, offering high transmission in the UV spectrum.

It can be manufactured in translucent or opaque form and the purity it offers makes it the ideal material for applications such as items of optical equipment which rely on UV transmission. An example of this would be equipment which uses UV rays in order to sterilise surfaces and or/equipment for medical purposes. The purity it offers also makes fused silica the material of choice for the manufacture of semi-conductor and laboratory equipment.

Edmund Optics has been a leading supplier of precision optics and optical components since 1942, designing and manufacturing a wide array of multi-element optical lenses, lens coatings, imaging systems, and optomechanical equipment. Led by a staff of skilled optical engineers and scientists, Edmund Optics is application focused and pursues new ways to implement optical technology, enabling advancements in industrial metrology, semiconductor manufacturing, life sciences, and more. Edmund Optics is a worldwide presence in industrial optics extending well beyond our original manufacturing plant and corporate headquarters in Barrington, New Jersey, USA.

For many applications, fused quartz glass provides sufficient levels of optical purity as well as the other shared properties detailed above, whilst being less expensive and time consuming to manufacture. For those reasons we will often recommend it to clients, particularly if they are seeking large-scale production of optical components or working to tighter budgets and deadlines.

Fused silica, for example, is manufactured using a process known as flame hydrolysis. Although this offers the highest possible level of purity it is also expensive, complex and time consuming, and is only needed in those components which demand the very highest levels of optical purity.

This means that fused quartz has a lower OH content than the synthetic alternative, as well as lower optical quality and more flaws and bubbles. In most cases, fused quartz glass is transparent and, despite being inferior in quality to fused silica, can still offer excellent optical, electrical and thermal properties, as well as being highly resistant to corrosion.

When a client comes to UQG Optics with a requirement they sometimes know whether they need fused quartz or fused silica, but in other cases they may not be entirely clear. We will draw on our expertise and experience to advise as to which of the materials will be best suited to the optical component in question.
