Filter IR685 IR-PAss S-serie 1"25 - Player One

Player One S series filter using high quality optical glass substrate and multi-layer composite coating technology, which has excellent optical performance in astrophotography.


Many years ago, Moon Prince introduced the IR685 infrared filter, which only allows red and infrared light with wavelengths greater than 685nm to pass, dramatically improving seeing conditions (because atmospheric ribs have less impact on light wavelengths).

Since then, the IR685 has become an excellent accessory for lunar photography. This IR685 filter is not the same as old IR685 filters. Our IR685 using the upgrade of double-sided multi-layer composite coating, iR685, will become your new magic weapon!
