What’s So Special About metaOPTIX™ Holographic Film Notch Filters?

Based on flexible, polymer substrates, metaOPTIX Holographic Film Notch Filters offer an unprecedented combination of performance, size, and freedom to configure for your specific application. Twelve models of metaOPTIX notch filters are the first in a series of planned new products available direct via our new online store. They are competitively priced, especially relative to their large area. Plus, our manufacturing process is more environmentally sustainable than conventional dielectric filters. How do we do all that?

We achieve high performance by recording many conformal layers into a photopolymer substrate, Covestro Bayfol® HX120. Each layer rejects a portion of the target wavelength, and the effect is additive. Optical density (OD) is >99% for red and blue, and >99.99% for green. Spectral bandwidth (SBW), a measure of the range of wavelengths rejected, is narrow, ranging from 7-13nm at OD 1.

We offer two large sizes, and two formats, providing huge freedom to configure for your application. For comparison, a typical COTS (commercial off-the-shelf) 25mm notch filter is shown below in red. Our small size (120mm x 70mm) is shown in green, and our large size (370mm x 70mm) is shown in blue. Since metaOPTIX are thin and flexible, they can be post-processed with a range of techniques, such as stamping, forming and laser cutting (Sticker version only; see product information for more details). We offer both a plain film and a sticker version with a self-adhesive backing, which can be mounted on various substrates, including curved surfaces.

We expect the unique properties of metaOPTIX holographic notch filters to stimulate and unleash creativity and be especially attractive for engineers and scientists in corporate R&D departments and university research labs. Notch filters are used in applications where it is necessary to block light from a laser, to obtain a good signal to noise ratio in Raman spectroscopy, for example, and in confocal or multi-photon microscopy, laser-based fluorescence instrumentation, or other life science applications.

Conventional thin film coated optical filter production involves deposition systems and a costly, slow coating process, typically using rare earth metals and scarce minerals. We use photopolymer films, and a process that is more environmentally sustainable, which together provide a cost advantage as well. COTS 25mm notch filters with SBW in the range of 15-20nm typically sell for US$500-800. For a limited time, you can order metaOPTIX for US$749 (large) or US$299 (small).

Want to know more about holography? 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. A new generation of holographic optical elements (HOEs) from META offers optical engineers new flexibility in system design. Based on recently developed dry processed holographic recording media, these unique optical components are designed from the ground up for efficient mass production. They boast spectral selectivity and tunable diffraction efficiency, high transparence, and can support wavelength multiplexing and complex optical functions within a thin planar form factor. Together these qualities make HOEs well suited to solve technical challenges that cannot be addressed by conventional optics. Applications include laser blocking filters, transparent displays, couplers for waveguides, and optical combiners in head mounted displays for augmented reality.

We hope you will join us!
