March 23, 2017, Karlsruhe, Germany - Edmund Optics (EO), the premier provider of optical components, introduces new Flexible Longpass Filters. These versatile cut-on filters offer deep blocking and excellent transmission over a large spectral range from 400 - 1600 nm to accommodate a wide variety of applications. The filters are constructed using ultra-thin, flexible polymers and dyes. Flexible Longpass Filters are scratch insensitive and provide equivalent durability to most industry hard oxide coatings, making them extremely robust.
Ultra-thin filters only 200 - 500 μm thick
Flexible Longpass Filters are made of hundreds to thousands of polymeric and dyed sub-layers. Using these stacked materials allows them to be ultra-thin, measuring only 200 - 500 μm in thickness. The filters are manufactured using a unique process combining features from plastic extrusion and fiber drawing processes. Able to conform to both flat and curved surfaces, the filters can be conveniently cut into complex shapes and small dimensions down to 0.5mm by the customer using scissors, blades, or lasers. The filters achieve high wavelength selectivity across the visible and near-infrared spectra and provide OD 2 blocking over that range. They offer VIS transmission of greater than 90% and have a clear aperture of greater than 90% of the whole filter.
Ideal for weight and space sensitive applications
These filters are customizable for OEM integration, with custom ultra-thin notch, edge, and bandpass filter design capabilities achievable. With their low cost, low weight, and thin and flexible characteristics, Flexible Longpass Filters are ideally suited for high volume consumable applications including vision and electronics or point of care devices for small and compact diagnostics equipment. Flexible Longpass Filters are in-stock and available for immediate delivery for fast turnaround and excellent value.
