Theia Technologies’ expanded line of ultra-wide angle, no distortion,
megapixel lenses now includes the SL183 varifocal model. Designed
for 1/3-, 1/2.7- and up to 1/2.5-inch image sensors, the lens provides
from 77 to 115 degrees horizontal field of view, with less than
one percent barrel distortion. The lens features True Zoom capability,
which allows users to set focus once and have the image remain in
focus while zooming. Linear Optical Technology optically corrects the
barrel or fisheye distortion.
