Injection molding of thick optical elements
Thick optical components are couldn't be manufactured using regular injection molding process due to surface deformations as explained below:
After injection plastic is boiling inside and cooled outside
As a result, warping of optical surface happens
Special manufacturing process to prevent thick lens optical surface warping was developed and used for mass production; kept in secret
Today we are able to inject 4 thick optical elements at once reducing the costs of production
