Specifications
The PICO 4 uses pancake lenses in combination with two small LCD displays, one for each eye, in the head-mounted display. This technology allows for a lighter headset with an increased image resolution. The pancake lenses have some drawbacks introduced by the light bouncing between the lens layers, but are generally considered to have fewer artifacts than the previously used Fresnel lens. There are a few features that have been introduced in this product: real-time hand tracking and a see-through mode in low resolution.
