Ask the people that sell them see: https://www.edmundoptics.com/optics/optical-mirrors/specialty-mirrors/cone-mirrors/"If I feed a 20 degrees cone mirror tip with a laser, would I get a conical beam of 20 degrees ? I do not want to use rotational scanning to get a conical beam shape.
Bosch uses 45 degree ones for leveling applications.
Thanks. I still wonder why a cone mirror can not be used for that. I have searched the internet, could not find an implementation for that.
Think about it.
If you direct a single, stationary laser beam at a mirror, no matter what shape the mirror is, all you're going to get is a single beam reflecting off of that mirror at some angle. Shape of the mirror is not a factor in this scenario.
