Aftermarket collimating and focusing lens assemblies for the Raytools BM06K cutting head. Choose the one you need from the list: the collimating assembly, Raytools 120BT0300Z (D37 mm, F100 mm, 6 kW), or the focusing assembly, Raytools 120BT2800Z (D37 mm, F200 mm, 6 kW). Each is the lens holder with its lens fitted, ready to drop into the head.
The collimator sits under the fiber connector in its black bracket holder and turns the diverging beam from the fiber into a parallel beam. The focusing lens sits lower in its stainless holder and brings that beam to the focal spot under the nozzle. The F100 and F200 pair is the standard BM06K setup for sheet cutting up to 6 kW.
A burned collimator costs power on every job. A damaged focusing lens shows as slow piercing, a wide or tapered kerf and dross that will not tune out. Replace the assembly that is damaged; the two are sold separately so you only buy what you need.

Burned or contaminated collimator
Contamination from a fiber change or a failed upper window reaches the collimating lens first. A burned collimator costs power on every cut. Replace the 120BT0300Z assembly and check the upper window.
Power loss with a clean lower window
If the lower protective window is clean and the machine still needs more power for the same plate, inspect the collimator and the focusing lens.
Burned or pitted focusing lens
Slow piercing, a wide kerf and dross that will not tune out usually point to the focusing lens. Replace the 120BT2800Z assembly and fit a new protective window at the same time.
Focal shift during long cuts
A contaminated lens absorbs power and heats up, so the focus moves as the job runs. A new assembly cures it where cleaning will not.
Keeping a spare
A spare assembly on the shelf gets a 6 kW machine back to work in minutes after an optics failure.

The collimating assembly (120BT0300Z, F100) is the upper lens in the black bracket holder under the fiber connector. The focusing assembly (120BT2800Z, F200) is the lower lens in the stainless holder above the protective window. Check the kit number on the holder you are replacing.
The collimating assembly 120BT0300Z fits both the old white and the new black BM06K. The focusing assembly 120BT2800Z is the new black type part; the old white type uses focusing kit 120BS3600Z, so check your holder before ordering.
No. A BM06K with an F150 focusing lens uses different kits (collimating 120BT2200Z with focusing 120BT2900Z or 120BT2300Z). This page is for the F100 and F200 pair.
No. It is an aftermarket lens assembly made to the same diameter, focal length and mounting as the Raytools kit. The Raytools number is shown so you can match the assembly you are replacing.
Check the kit number on your current holder or in the head's parts list, and confirm the lens diameter and focal length. Collimating and focusing assemblies are not interchangeable.
Fit it in a clean area with clean gloves, handling the holder only. Fingerprints on a lens burn into the coating under laser power.
