Question 1

What is the function of a collimating lens?

Accepted Answer

It aligns and stabilizes the laser beam for accurate cutting results.

Question 2

What is the diameter and collimating length of the BOCI BLT 421S collimating lens?

Accepted Answer

This lens has a 32mm diameter and 100mm collimating length (32×100), designed specifically for the BOCI BLT 421S laser cutting head.

Question 3

What does a collimating lens do in a fiber laser cutting head?

Accepted Answer

It aligns and parallels the diverging laser beam as it exits the fiber, ensuring a stable, uniform beam before it reaches the focusing lens for cutting.

Question 4

Is this an original BOCI BLT 421S collimating lens?

Accepted Answer

Yes, this is a genuine original lens with full assembly, verified for OEM-grade optical clarity and coating quality.

Question 5

What power rating does this lens support?

Accepted Answer

This lens supports fiber laser systems up to 8KW, matching the BLT 421S head's standard operating range.

Question 6

How do I know if my collimating lens needs replacing?

Accepted Answer

Look for beam misalignment, reduced cutting power at the material, visible burn spots or scratches on the lens, or inconsistent cut quality across a job.

Question 7

Is this compatible with the BLT 643H head instead of the 421S?

Accepted Answer

No — collimating lenses are diameter- and length-specific to each head model. The BLT 643H uses a 37mm x 100mm collimating lens; this 32mm x 100mm lens is for the 421S only.

Question 8

Should I replace the collimating lens and focusing lens at the same time?

Accepted Answer

Not necessarily — they wear independently. However, if you're already servicing the head, checking both together helps avoid a second downtime event soon after.
