New at AHF: Ultra-thin Optical Filters from Everix

Innovative and Flexible Filters on Polymer Basis

AHF puts you in the technological pole position! The new, innovative polymer-based filters are ultra-thin (0.1 – 0.5 mm) and can be installed particularly well where conventional glass filters reach their limits. They can be applied to curved surfaces and cut to special shapes. This is made possible by an innovative, patented thermal manufacturing process. Take advantage of these new possibilities for your project!

Standard Filter Designs

Everix's ultra-thin, all-plastic optical filters feature total thickness in the range 100 - 500 microns, suitable for device miniaturization, optical path length reduction, and innovative designs requiring non-traditional geometries. It also provide an ideal balance between cost and performance for most applications

Available standard filters:

Single- and multi-Notch filters (OD6+)
Bandpass filters (FWHM > 25 nm, OD 2–4)
Narrow bandpass filters (FWHM < 10 nm, OD2–6)
Longpass- and shortpass filters (OD2–4)

Innovative Filters for Innovative Applications

Compact & Complex Forms:
For optical devices with limited space, or for the most innovative optical designs benefitting from non-traditional filter geometries.
Conformal to Free-Form Optics
For retrofitting simple or complex optical filter designs to any non-flat optical surface that challenges traditional coating methods.
Compensated Angular Shift:
For optical devices that can benefit from an interference filter in a curved geometry to compensate for (and even completely eliminate) the undesired spectral shift of thin-film interference filters.
Enhanced Signal-to-Noise Ratio:
For optical devices where every micron of gap between a source of light and a sensor means reduced signal or increased noise.
Light Weight:
For devices that can benefit from reduced substrate weight or a replacement of filter-coated glass components with plastic optics.

Markets and Applications

Life Sciences and Med. Tech.

Everix ultra-thin optical filters increase signal-to-noise ratio by reducing the gap between tissue and detectors. They also enable better light emission and light capture with simplified optical designs thanks to the conformity and moldability of our products onto curved surfaces to reduce or even completely eliminate angular shift in thin-film filters.

Applications:

Fluorescence microscopy
Imaging and sensing

Consumer Electronics

The ultra-thin optical filters enhance signal-to-noise ratio and range for 3D sensors and Time of Flight sensors in consumer electronic devices.

Applications:

The filters also address a major unmet need in consumer electronics segment for high-performing filters on curved plastic surfaces in devices such as AR/VR headsets where PVD and other coating methods are not sufficient either for scaling or for performance on plastic substrates. Everix ultra-thin, plastic-based filters can be molded to complex curvatures at scale while maintaining optical performance commensurate to vacuum-coated filters.

The Technology

Everix's manufacturing platform is based on thermal drawing of a scaled-up multi-layer block (a preform) down to a substrate-free ultra-thin optical filter. This process is similar to how optical fibers are thermally drawn from a fiber preform and demonstrates scaling economics significantly better than the traditional coating-based methods of manufacturing optical filters.
