Check Compatibility Before Ordering
Confirm that your machine uses a 24mm focal tube barrel and accepts the included mounting and air assist components. A matching barrel diameter does not guarantee compatibility with every laser head.
Important: This assembly accommodates a 20mm diameter focusing lens, but the lens is not included. Confirm the required focal length and working distance for your machine before purchasing a lens.
Installation Note: Turn off and disconnect your laser before servicing its optical assembly. Verify lens orientation, proper seating, air assist connections, and optical alignment before returning the machine to operation.
