700nm Optical Bandpass Filter (FWHM 40nm)

The 700nm optical bandpass filter is designed to transmit light centered at 700nm with a Full Width at Half Maximum (FWHM) of 40nm, ensuring high selectivity and precision. This filter effectively blocks unwanted wavelengths outside its range, making it ideal for applications requiring accurate spectral isolation and enhanced performance in the red region of the visible spectrum.
