What is the correct way to focus my E40 that extends beyond the main body?
Mark
This is the latest version of the E40, with adjustable focal length and compatible with needle-type air assist.
Great!
The focus point of my recently bought E40 laser is 14mm but 28mm?
Has something changed in the construction?
Best regards,
Marc
Yes, the latest E40 module has a longer focal length than the old version.
Iv’e been using 5mm for focus on my E80, have I been wrong? thanks
This is for the Neje E40…

In this forum about E40 focal length there is different infomration, this post says for E40 where air assist extends past bottom frame the length must be 14-15mm, but other posts says 30.1mm and another post 28mm, its not clear, how do I know?
The E40 actually has three versions: 5mm focal length, 15mm focal length, and 30mm focal length.The focal length currently on sale is 30mm
This is what I go by…mine actually works best at 13mm. I do not have the cone installed like the one on the left.

There will be a little difference, this is normal
