holoOPTIX® SLANT is a range of holographic notch filters that offer unique diffraction characteristics in an industry standard 1” diameter form factor. These filters offer narrow, high optical density stop band like conventional notch filters, but instead of reflecting the incoming light specularly (angle of incidence equals angle of reflection) the diffracted portion of the beam is anomalously reflected into an angle that is different than the angle of incidence.
The META Shop is offering this holoOPTIX® SLANT Notch Filter at 457nm light incoming at normal into an anomalous reflection angle of 45°. The volume holographic grating is protected within a glass sandwich structure. All air interfaces have a broad band antireflective coating to maximize the out of band transmission. The wavefront distortion is less than 1λ at 633nm for the transmitted beam, and less than 4λ for the anomalously reflected beam.
The filter is housed within an aluminum black anodized mounting ring. The ring is marked with the direction of the incoming beam, and the azimuth of the anomalous reflection.
By eliminating the need to tilt the filter in the optical path, this range of filters gives optical engineers new options to compact and miniaturize their designs.

At META we design and manufacture functional materials that are more sustainable, higher performing and cost less than the competition. These are complex, structured materials that perform special functions, utilizing light and other forms of energy in new and often surprising ways. Our products are designed using algorithms and engineered at microscopic levels, creating novel functional materials that mimic nature and metamaterials with new properties and capabilities that go beyond those found in natural materials.
