525nm Optical Bandpass Filter with FWHM 40nm

A 525nm optical bandpass filter with a Full Width at Half Maximum (FWHM) of 40nm is designed to transmit light centered around 525nm while blocking wavelengths outside the specified range. With a relatively wide bandwidth, this filter is ideal for applications requiring more light transmission within the green part of the spectrum, providing flexibility for various optical systems.
