Laser lens pack for diode lasers



Upgrade your diode laser with a high-quality laser lens package.Get a spare lens and high-quality and effective lens for accurate and efficient laser cutting and laser engraving.


Endurance offers a full laser lens pack for your diode laser.

The accuracy of laser cutting and laser engraving depends on the laser lens quality.
The better lens – the better the result you will get.
A better lens means a better (smaller) laser beam spot.


If the lens is made out of plastics or is defective then it will not be useful for laser cutting or laser engraving.
The engraving will be blurred and fuzzy.


Endurance offers a laser lens pack for laser makers and professionals. There are 4 types of lenses that we are offering:
• Regular 3 element lens [installed by default] (black one)
• G2 lens (golden with a small lens)
• G7 lens (black)
• G8 lens (black) Getting started with laser lens pack


3-element lens (Cleanest beam profile, best for low power lasers)

The 3-element lens has a long focal length, low divergence, and clean beam profile but it has a significant output loss.
Advantage Tight laser beam with the cleanest beam profile
Downsides 70% efficiency (1W diode = 700mw using this lens)


G2 lens (best for power)

The G2 is a single lens enabling the maximum true power of the laser diode for rapid close-range burning and engraving.
Advantage 95% efficiency, reduces the beam aperture
Downsides Increase the beam divergence (thickness) and the beam profile


G7 lens (Balanced Multi-Purpose Perfection)

This lens is a cross between the divergence and the power lens. With the G7, the beam divergence won’t increase as it does with the G2 and you will still get very close power of the laser diode.
Advantage 88% efficiency, long focal length and increases beam aperture.

Keep in mind that a low-quality Chinese lens might have some optical artifacts and other issues that might have a poor effect on laser cutting and laser engraving.

All these lenses were designed by professional optics suppliers and tested in the Endurance laser lab.
