As an important optical element, long-pass filter has been widely used in digital image, biomedical cosmetology, fingerprint recognition and other fields. Its characteristic is to let the light in one band pass through while the light in another band cut off. The long-pass and short-pass filters have the characteristics of high throughput, wide cut-off band and good film firmness. The filter products are manufactured according to the customer's requirements.
Longpass filters feature high transmission in the pass band combined with superior blocking in the rejection band. With a rejection band optical density of 4.0 combined with >91% in the pass band these filters are ideal for a wide variety of applications.
