Ultra-Thin Longpass Filters

Description

Flexible Longpass Filters offer deep blocking and excellent transmission over a large spectral range from 400 to 1,600 mm to accommodate a wide variety of applications. Scratch insensitive filters are built with ultra-thin, flexible polymers and dyes, and provide equivalent durability to most industry hard oxide coatings.

 

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 200-500μm 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.

 

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.
