Hi! I know this is probably a book that is not in your native language. However, It would really help me If you tried your best to find this book!
The closest I've been to finding it : https://rusneb.ru/catalog/000199_000009_005159455/ -> A public russian electronic library, but I could not get it out of there...
I appreciate the time it took you to read through this, that also helped!
Don't know how this might be helpful, but the book looks something like this (yeah, its really old):
Оптические контрольно-измерительные приборы (1937) Бартенев А.Г. ОНТИ
