I actually found one implementation with a cone mirror

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 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.
