Thorlabs FL1064-10 bandpass filter

Product Description

Thorlabs FL1064-10 Bandpass Filter – 1064 nm Center Wavelength, 10 nm FWHM

A precision hard-coated dielectric bandpass filter from Thorlabs, designed for spectral filtering at the common 1064 nm laser wavelength. With a 10 nm full-width half-maximum (FWHM) bandwidth and high out-of-band rejection, this filter is ideal for laser line cleanup, fluorescence isolation, and noise reduction in imaging and detection systems.
