A BM110 / BM111 head needs a collimating and a focusing assembly. This focusing assembly pairs with the 120AG0600A collimator; the other focusing lengths are listed too.
| Assembly | Use |
|---|---|
| Collimating F100 (120AG0600A) | Collimator, sits behind the fiber connector |
| Focusing F155 (120AG0800A) | General cutting, the usual standard length |
| Focusing F200 (120AG1400A) | Thicker plate, larger spot and more depth of focus |
Replacing a damaged assembly
Fit a complete assembly when the lenses are damaged and you would rather not handle loose optics.
Changing focal length
A different focal length assembly changes spot size and depth of focus.
