Ultra-Thin Longpass and Shortpass Filters are designed and constructed out of ultra-thin, flexible polymers and dyes. These filters are scratch insensitive and as durable as most industry hard oxide coatings. Comprised of hundreds to thousands of polymeric and dyed sub-layers, these filters can achieve high wavelength selectivity across the visible and near-infrared spectrum. Due to the low cost, low weight, and thin and flexible nature, these filters are perfect for high volume consumable applications such as vision and electronics or point of care devices for small and compact diagnostics equipment.
