Optoma has released semi short and extra long lenses for EH503, EH505, W505 and X605 ProScene projectors.
Projectors can now be situated as far back as 10.8 metres and as close as 1.67 metres to achieve a 100-in image (based upon WUXGA resolution projector).
The semi-short throw lens has a near 1:1 throw ratio and the extra-long lens has a zoom range of x1.67, which enables an image of between 3 metres to 20 metres to be projected. All lenses, including the 0.8:1 short throw lens, can use the full lens shift range.
