Optoma has launched a range of ultra short throw projectors designed for businesses, schools and colleges. The range includes Full HD 1080p, WXGA and XGA resolutions.
The projectors offer brightness of 3,600 lumens and are suitable for teaching or meeting rooms with ambient light, and provide an expected lamp life in eco mode of 15,000 hours.
As well as the usual dual HDMI + MHL, VGA and composite inputs, presentations can be plugged in from a USB device and played via the projector’s built-in photo and document viewer without the need for a laptop or PC. This also supports Excel, Word, PDF and JPEG files.
All models have vertical and horizontal keystone and four corner geometric adjustment which ensures accurate installation. This is helpful for uneven walls or where a projector placement is awkward or needs to be installed at an angle.
The throw ratio of 0.25:1 for the 1080p model, 0.27:1 for the WXGA model and 0.33:1 for the XGA model means they can project a 100-in image (diagonal) from just over 0.5m away.
Full support is provided for Crestron, Extron, AMX, PJ-Link and Telnet LAN commands, which allow almost all aspects of these projectors to be controlled remotely across a network.
An audio input is also included which cuts out the need for additional costly audio hardware and cabling. For wireless presentations from a laptop or mobile device, the Optoma wireless WUSB adapter (sold separately) can be connected to the USB output. The chassis design incorporates a built-in speaker that delivers 16W of audio.
