After long struggle, we had slight progress to polish crystal and glass wafers inside of our company. Every process and equipment is on our own and still it takes a lot of time and cost. However, it is really great thing to get customized mirrors, windows, etc. from raw materials, as well as free opportunity to design unique optical systems.

We installed OpenCV4 for something like wafer inspection which shall be necessary in future. It took 3days to complete it including the initial study of Cmake with our old Ubuntu machine. What program shall we run firstly? Maybe with an USB camera?

Yesterday, we printed a nut by 3D printer. It's necessary to make the designing hole only a little larger than the actual one. Looks okay. however it has collapsed after some in and out of a metal screw. PLA is elastic and easy to changing it's shape for the repeating stress

Category：casting
We are casting glass pieces in a furnace. It's melting at the temperature over 700℃. Over 800℃, it is still sticky and do not go in a casting block like fluid. In order to make a industrial shape, we have to think something good way.

We have obtained CO2 LASER parts from China. They consists of only sealed CO2 tube and power supply. How do we assemble them as a functional module by ourselves. It's a long way to go.
