Holographic Optical Components
High-performance, competitively priced, holographic optical components, available direct via our online store.
metaOPTIX™ holographic optical components are fabricated on META’s Holography platform. Interference patterns are recorded with a laser into a light-sensitive photopolymer material to form Volume Holographic Gratings (VHGs), which transmit or reflect light in various ways, depending on the geometric structure of the recorded pattern.
VHGs have a number of advantages in optical designs:
- Wavelength selective and angle specific, with high transparency
- High diffraction efficiency
- Thin (<100μm thick)
- Complex and multiple optical functions
- Ready for integration
metaOPTIX™ Holographic Film Notch Filters
Notch Filters are Optical Filters that selectively reject a portion of the spectrum, while transmitting all other wavelengths. They are used in applications where it is necessary to block light from a laser, as in the machine vision application show below, for example, and in confocal or multi-photon microscopy, laser-based fluorescence instrumentation, or other life science applications.
Based on flexible, polymer substrates, metaOPTIX Holographic Film Notch Filters offer an unprecedented combination of performance, size, and freedom to configure for specific applications. Twelve models of metaOPTIX notch filters are available direct via our online store. They are competitively priced, especially relative to their large area. Plus, META’s manufacturing process is more environmentally sustainable than conventional dielectric filters.
High performance is achieved 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.
META’s metaOPTIX™ holographic optical components offers two large sizes, and two formats, providing huge freedom to configure for specific applications. For comparison, a typical COTS (commercial off-the-shelf) 25mm notch filter is show below in red. META’s smaller size (120mm x 70mm) is shown in green, and the larger size (370mm x 70mm) is shown in blue. 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. They can be post-processed with a range of techniques, such as stamping, forming and, for the sticker version only, laser cutting (see product information for details).
A More Sustainable and 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. 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, metaOPTIX Holographic Film Notch Filters are available for US$299 (small) or US$749 (large).

View our 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.
