FAQ:

Q: What is the focal length of a laser?

A: Focal length is the distance from the lens to the material for the laser converge into the best focal point. If a lens is listed as 2″. You measure 2″ from the lens to the material, this will be the tightest point the laser can go before it starts to re-expand again losing focus. WHAT ARE THE BLACKTOOTH LENS SIZES AND FOCAL LENGTH SPECIFICATIONS?

Q: What is the focal length of the lens and mirror?

A: The lens is 20mm wide and a 50.6mm focal length (the one included). This lens will stand up to at least 30PSI air assist. The mirrors are 25mm wide mirrors. Focal length is the distance from the lens to the material for the laser converge into the best focal point.

Q: What is the best focal range for a laser lens pack?

A: For a 3 element lens, the best focal range is 57.6 mm For a G2 lens, the best focal range is 6.8 mm. A Practical Guide to Handling Laser Diode Beams-Springer Netherlands (2015) (PDF) Learn more about laser lens pack

Q: What is the best focal length for laser engraving?

A: The tolerance on the 2″ focal length lens is short and will provide the smallest point burn, or tightest kerf. This is especially good for photo engraving and laser cutting of thin materials at a single pass.
