Edmund Optics Flexible Longpass Filter. Image Credit: Edmund OpticsEdmund Optics (EO) has introduced a new line of flexible longpass filters designed to offer deep blocking and excellent transmission over a large spectral range (400-1600nm). The filters are constructed of thousands of polymeric and dyed sub-layers which allow them to be ultra-thin (200-500μm thick). Edmund Optics manufactures the filters using a process that combines features from plastic extrusion and fiber drawing processes.

Able to conform to both flat and curved surfaces, these flexible longpass filters can be cut into complex shapes and small dimensions by the customer simply using scissors, blades, or lasers. Inexpensive, light weight, and flexible, these filters are ideally suited for high volume consumable applications such as compact diagnostic equipment and point of care devices. The filters offer over 90% transmission in the visible range with a clear aperture greater than 90% of the whole filter.
