Hoya B440 Blue Optical Filter is an optical material designed to selectively transmit blue light while attenuating other wavelengths.
It is made from Hoya B440 glass, a borosilicate glass known for its excellent optical properties. The filter is specifically engineered to allow the passage of blue light while effectively blocking unwanted visible and infrared wavelengths. This makes it well-suited for applications such as fluorescence microscopy, blue LED lighting, and imaging systems where precise control over the transmitted light spectrum is crucial. The Hoya B440 Blue Optical Filter provides high transmission in the blue range, enabling enhanced contrast and improved image quality in various optical setups.
