hey friends i am going to start a new hmd project and since lens are nt avilable near me so im trying to make my own so i want to know which kind of lens would work best (since i am casting my own) i am going to try two techniques
1. rasin casting
2.molding some acrylic
I have a lot of experiments about it.
I spend two years making lenses in all shapes for a wide fov hmd.
first of all, it is very important to have a drill press or adapter.
without this tool you cannot polish that fast and precisely.
Second: your mandrel has to be smooth enough to avoid too much grinding and polishing work.
The easiest lens to make are the planar-convex and a planar-concave ones.
If you want to have double-concave or -convex, you can use glass adhesive to glue both planar sizes together.
Do not hesitate to ask what you want to know about diy lenses.
