This yellow glass filter is designed for fluorescence photo or videography. The yellow filter will block the blue light coming from blue LEDs or excitation filters mounted on strobes and allows fluorescence from marine life to pass through. This is a snap-on filter that is easy mounted or removed from the MFO in a matter of seconds and while diving. 

This product requires the MFO scratch absorber and cap kit (EOC-MF3-FRNT). Please note this is a special order - A month is required before shipping.
