Question 1

Can this lens support high-power laser machines?

Accepted Answer

Yes, it supports up to 15KW laser systems.

Question 2

What is the difference between a collimating lens and a focusing lens?

Accepted Answer

The collimating lens straightens and parallels the raw laser beam right after it exits the fiber, while the focusing lens concentrates that parallel beam to a precise cutting point — both work together in the optical path.

Question 3

What is the collimating length (CL) of this lens?

Accepted Answer

This BOCI BLT 643H collimating lens has a 100mm collimating length and 37mm diameter, matched specifically to the BLT 643H head assembly.

Question 4

Is this an original BOCI collimating lens?

Accepted Answer

Yes, this is a genuine original BOCI BLT 643H collimating lens with full assembly, verified for OEM-grade optical quality.

Question 5

How do I know if my collimating lens needs replacement?

Accepted Answer

Signs include beam instability, reduced cutting power at the workpiece, inconsistent cut quality, or visible damage/burn marks on the lens coating.

Question 6

Is this lens compatible with other laser head brands besides BOCI?

Accepted Answer

This assembly is specifically designed for BOCI BLT 643H heads. Confirm your exact head model before ordering, or reach out via WhatsApp for compatibility verification.

Question 7

What causes a collimating lens to fail prematurely?

Accepted Answer

Common causes include contamination from cutting debris, thermal stress from prolonged high-power use, or improper installation/alignment during servicing.

Question 8

What's the difference between this and the BLT 643H Focusing Lens listed on your site?

Accepted Answer

Both are optical components for the same head, but serve different stages of the beam path — the collimating lens (100mm CL) shapes the beam early, while the focusing lens (200mm FL) concentrates it at the cutting point. Most services replace both together during a full optics service.
