The NEC NP16FL is an accessory lens offering a fixed 0.76:1 throw ratio, specifically engineered for use with compatible NEC NP-PX series professional projectors. This short-throw capability is particularly useful in environments like conference rooms, lecture halls, and exhibitions where space limitations necessitate placing the projector close to the screen while still achieving a large projected image size. The lens itself features a fixed focal length of 11.6mm and an aperture range of f/1 to 85. Its design emphasizes user-friendly installation, requiring no special tools for attachment to the compatible projector bodies.
