LUMINA narrow bandpass filters are designed to transmit a specific wavelength range while effectively blocking out-of-band radiation.
Through precision thin-film interference coating technology, our filters deliver high transmission efficiency, excellent spectral selectivity, and reliable blocking performance for demanding optical systems.
Custom designs are available across UV, visible, and infrared wavelength ranges to meet diverse industrial and scientific application requirements.
