The Appotronics AL-ML100MA is a standard zoom lens with a 1.00 - 1.60:1 throw ratio for Appotronics M Pro series laser projectors, supporting the AL-MK650A, AL-MK750A, AL-MH650A and AL-MH750A models. It covers the medium projection distances found in most professional installations, making it suitable for conference and lecture halls, museums, media and architectural projection, immersive rooms and event staging. As a guide, projection distance is roughly the image width multiplied by the throw ratio, so for a 3 m wide image the lens would sit about 3 to 4.8 m from the screen. The lens offers motorised zoom and motorised focus, which is valuable for ceiling or hard-to-reach mounts and for repeatable alignment in multi-projector setups, and it supports vertical lens shift of ±50% and horizontal shift of ±20% for flexible image positioning without moving the projector. Aperture is F2.1 - 2.3 and the lens weighs about 0.7 kg. Finished in black. Check the exact model of your projector before ordering.
