holoOPTIX™ Holographic Film Notch Filters First in a Series of Product Families
HALIFAX, November 18, 2020 – Metamaterial Inc. (“Company” or “META”) (CSE: MMAT) a developer of high-performance functional materials and nanocomposites, today announced it has begun direct sales via a new online store. First in a planned series of new product families are 12 models of holoOPTIX Holographic Film Notch Filters. Notch Filters are Optical Filters that selectively reject a portion of the spectrum, while transmitting all other wavelengths. META’s optical filters, based on volume holographic optical elements (vHOE), are designed to be both more environmentally sustainable and less costly than conventional thin film coated optical filters. The Company plans to exhibit and introduce new products at two upcoming tradeshows in Japan and the U.S.
“Alongside our growing pipeline of custom development projects with world-class OEM partners and customers, we are delighted to begin introducing a range of standard products in order to make our state-of-the-art technology accessible to a wider range of potential end users,” said George Palikaras, President and CEO. “Our software and AI-enabled platform technology and growing design library enable us to offer rapid prototyping and customization to help customers further develop their applications.”
One example of a custom notch filter application is the award-winning metaAIR® laser glare protection eyewear. Worn by pilots, metaAIR® filters the light from green lasers without distortion of the remaining color spectrum and thus protects pilots’ eyes while ensuring no added operational risk. META also offers laser protection for law enforcement applications, for use by helicopter pilots and crew, as well as personnel on the ground.
Large Area, Flexible Substrate Format Supports More Possible End-User Configurations
holoOPTIX notch filters are thin, transparent, polymer-based components, offering high optical density (rejecting more than 99% of the target wavelength) and high out of band transmission. While most standard COTS (commercial off-the-shelf) notch filters are offered in a 25mm (1 inch) round format, holoOPTIX substrates are much larger, available in either 370mm x 70mm (14.56 x 2.75 inches) or 120mm x 70mm (4.72 x 2.75 inches) sizes. They can be post-processed with a range of techniques, such as stamping, forming and laser cutting to meet specific application requirements. There are two configurations: a thin flexible ready to use film, and a film with a high tenacity, optically clear adhesive backing, allowing the filter to be applied to various substrates – including curved surfaces. Notch center specifications include 447nm, 532nm, and 635nm (blue, green, and red).
“The unusually large area and polymer substrate format of holoOPTIX offers unprecedented freedom to develop new application configurations. We expect this should be especially attractive for engineers and scientists in corporate R&D departments and university research labs,” said Andrew Mark, Manager of Optical Engineering and Metamaterial Design at META.
holoOPTIX Offers High Performance at Competitive Cost
Spectral Bandwidth (SBW) is a measure of the range of wavelengths rejected by a notch filter; the SBW of metaOPTIX is 7-13nm. Typically, the narrower the SBW, the higher the cost, because competing products require deposition of many layers of dielectric coatings. COTS 25mm notch filters with SBW in the range of 15-20nm typically sell for US$500-800. holoOPTIX achieves a narrow SBW by writing many layers inside the photopolymer substrate with a laser, a faster and less material intensive process.
META will be exhibiting at FILM EXPO, the world’s largest advanced film and equipment show, December 2-4, 2020 in Tokyo, and at PHOTONICS WEST, hosted by SPIE, The International Society for Optics and Photonics, March 6-11, 2021, in San Francisco. The Company plans to introduce a wider range of holographic products at Photonics West. Standard products based on META’s proprietary NANOWEB® transparent metal mesh, fabricated with patented Rolling Mask Lithography (RML®) are also planned.
On Monday, November 23, at 1:00PM Atlantic Standard Time (Noon EST, 9AM PST), META will be hosting a webinar: Modern Holographic Optical Elements with Dr. Andrew Mark.
META’s Holographic Technology Offers a More Sustainable, Cost-Effective Solution
Conventional thin film coated optical filter production involves deposition systems and a costly, slow coating process, typically using rare earth metals and scarce minerals. META uses photopolymer films, and a process that is more environmentally sustainable, which together enjoy a cost advantage as well. There are many potential uses, for example: to protect sensors used in ADAS (advanced driver assistance systems) and autonomous vehicle systems, in contrast enhancement filters for sports eyewear, and in biomedical instruments used for fluorescence (used to measure compounds in a solution) and Raman spectroscopy (used to identify specific molecules in chemical analysis).
