Custom Absorbing Yellow Filter Glass Lens JB1 JB9

Custom Absorbing Optical Yellow Filter Glass Lens JB1 JB9   Introduction to JB1 & JB9 Yellow Absorptive Glass Filters   JB1 and JB9 are classic types of yellow-colored glass filters manufactured through a traditional process of melting raw materials with specific metal oxides. They belong to the category of absorption filters, meaning they work by absorbing unwanted wavelengths of light and allowing only the desired portion of the spectrum to pass through.   These filters are part of a larger family of Schott glass filters (or similar standards from other manufacturers like Hoya or Chinese equivalents), which are widely used in optics, photography, scientific instrumentation, and industrial applications.   Specification: Key Characteristics:   · Type: Absorption Filter · Color: Yellow · Material: Optical Glass · Primary Function: To transmit longer wavelengths (yellow, red, infrared) while blocking shorter wavelengths (blue, ultraviolet).   ---   How They Work (Absorption Mec…
