448nm Notch Optical Filter

The 448nm Notch Optical Filter is designed to selectively block light around 448nm with high optical density (OD4-OD6) while transmitting other wavelengths at >90% efficiency. Utilizing advanced dielectric coating technology, it ensures minimal signal distortion and enhanced signal-to-noise ratio. Key applications include Raman spectroscopy (blocking pump lasers for scattering detection), biomedical imaging (eliminating fluorescence noise), and laser safety systems (protecting optical components). Customizable parameters such as angle of incidence, bandwidth, and multi-notch configurations are available for complex integration
