Upgrading your optics in your laser machine is one of the best investments you can do for your machine.
You gain better cutting, finer engravings and a better life span of your optics.
Different types of mirrors
MO
SI
CU
K9
What to choose
For our small K40 machines there is no need to go with anything other than MO or SI mirrors.
The gain a CU mirror might bring is very small on a 30-40w machine.
SI is a bit better but needs good cleaning and often, and are more expensive.
MO can take a bit more beating but are cheaper and has a bit lower reflectance.
Cleaning and maintenance
Keeping your optics clean are as important in your laser as it´s for your glasses (if you wear any).
Use micro fibre cloth or better to clean them, never rub on the surface or use force. Denatured alcohol or acetone will clean your mirrors.
A note, strong alcohols like acetone will destroy shitty lenses, so be aware if you cheap out on lenses that cleaning might destroy them.
In the list below i list good sellers with perfectly good products.
