Optical filters are designed to selectively transmit or block specific wavelengths of light, enabling precise spectral control and purification. In fluorescence imaging, for example, the accurate control of transmission and cutoff wavelengths plays a critical role in achieving high image quality. Optical filters are widely used in photolithography equipment, imaging systems, fluorescence microscopes, industrial inspection systems, and optical sensors.Product Items:・Single Bandpass Filters・Multi-bandpass Filters・Longpass Filters・Shortpass Filters・Neutral Density Filters・Color Filters
