Applications for 1064nm Bandpass Filter

One of the applications of a bandpass optical filter with a 1064 nm CWL is to block the unwanted laser lines or ambient light in Nd:YAG laser systems. Nd:YAG lasers are widely used in industrial, medical, and military applications, such as welding, cutting, drilling, marking, surgery, and laser range finding. A bandpass filter with a 1064 nm CWL can isolate the fundamental laser line from the higher harmonics or other sources of noise, and improve the signal-to-noise ratio and the performance of the system .

Another application of a bandpass optical filter with a 1064 nm CWL is to enhance the fluorescence detection of certain biomolecules, such as green fluorescent protein (GFP) or fluorescein isothiocyanate (FITC). These molecules emit green light when excited by blue light, and a bandpass filter with a 1064 nm CWL can block the excitation light and transmit the emission light, increasing the contrast and sensitivity of the fluorescence imaging.
