Kopin brags about providing OLED chips and Pancake optics for these glasses
In 2019, Kopin published
conference papers with this chart including pancake:
.. which does suggest reduced field of view, along with greater eye relief;
that steampunk appearance is not simply a style choice..
This from their 2017 annual report:
"We offer a variety of optical lenses some of which we have developed internally
and others we license the rights to sell the lenses. We also offer a variety of backlights,
some of which we have developed internally and some of which are “off-the-shelf” components.
The lenses come in a variety of sizes with the smallest being our Pupil,
followed by our Pearl, Prism, Pantile, and Pancake lenses.
The different sizes of lenses give us and our customers design flexibility
when creating headset systems.
There is a trade-off between the lens size and the size of the perceived image to the viewer.
For example, a Pearl lens will provide the viewer with an image
approximately equivalent to what the viewer would see looking at a smartphone,
whereas a Prism lens will provide the viewer with an image approximately equivalent
to what the viewer would see looking at a tablet.
A Pearl lens, however, is smaller than a Prism and would enable a more fashionable design.
Therefore, a customer designing a consumer-oriented product may choose a Pearl lens
but a customer designing an enterprise-oriented product might choose a Prism Lens.
We use third parties to manufacture these lenses."
.. where the third party for Pancake appears to be 3M.
