SEOS Ultra Wide Field-of-View

Head Mounted Display


The SEOS HMD 120/40 provides a stunning 120 degree x 67 degree field of view for true immersive virtual reality systems. Left and right 1280 x 1024 images are displayed with a central 40 degree stereo overlap. The display is ideally suited to driving simulation, flight simulation, individual soldier training, and all applications in which a wide field-of-view is important.

SEOS HMD 120/40 incorporates a patented new catadioptric eyepiece that is not conventionally refractive. The result is a large pupil, providing high tolerance to eyeball movement without losing regions of the field of view. The wide range of optical correction (+/- 4 diopter) accommodates most eye-glass wearers. The image distance can be varied from collimated to 0.25m by the use of the eyepiece focus adjuster.

SEOS HMD 120/40 looks boxy, but it is lightweight and very comfortable to wear. A patented mounting method provides for conforming to head shapes. There is no need to lean forward or backward.
