Deep cutting lenses
There are three types of primary lenses: deep-cutting, a combo of cutting and engraving, and an engraving-only lens. Deep-cutting lenses have a focal length of 3 inches or more. Due to their size, they are pretty much cut-only lenses, but depending on your setup, a deep-cut lens might cut up to 3 inches worth of acrylic or plywood. most deep cut lenses will probably max out at about an inch or an inch and a half of acrylic or plywood. In order to get more than that, you would have to have a very powerful specialized set up. if you would like to purchase a deep cut lens, it is generally better to buy it in the lens housing rather than as a solo lens. Solo lenses often will not fit correctly into your pre-existing housing. in order to determine the correct lens. The best thing to do is to measure the OD of your laser, lens, housing, and order your deep cut lens with a match as close as possible. Often these can be purchased in sets with engraving lenses as well. Once you set up your new lens, you'll have to retest your focal length in order to determine the correct distance. I do not recommend using the system like this with auto bed leveling as it may cause damage. You should also be aware that the lens housing may be significantly longer and may collide on homeing. it is best to test to see if you have any collision issues before setting up your tube for the first cut. You can also remove the tube after you are done in order to prevent collisions. you may also need to purchase an adapter to hook up your airline to the tubing as it mostly only comes in small sizes when it is connected to the large focal length lens housing. Just a small tip, the adapter I purchased was not a perfect fit, and I was able to use a small amount of electrical tape on the smaller tube in in order to make it fit in the adapter. companies like American Photonics supply some of the best kits if you were looking to do multiple focal length such as the one in the link below.
