Yes, partially. This is what I wonder if works or not:

This is the article: Generation of hollow conic beams using a metal axicon mirror | Optical Engineering | SPIE

I actually found one implementation with a cone mirror http://opticalengineering.spiedigitallibrary.org/data/journals/optice/22102/084002_1_1.png This is a larger than 45 degrees mirror. If the mirror angle were less than 45 degrees, would the conical shape form on the opposite i.e away from...

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.

Thanks I did now. They suggested Axicon conical prisms. I am trying to generate a continous conical beam of 20 degrees without rotational optics. I thought I could do it with a cone mirror that has an angle of 20 degrees.

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.
