Preset optical components in a computer numerically controlled machine
A system can include a head of a computer numerically controlled machine configured to deliver electromagnetic energy sufficient to cause a change in a material at least partially contained within an interior space of the computer numerically controlled machine. The system can further include an optical system comprising a plurality of optical elements in the computer numerically controlled machine. The plurality of optical elements can be oriented at a fixed angle to each other to deliver the electromagnetic energy from the head to the material.
1. A system comprising:
a head of a computer numerically controlled machine configured to deliver, to a material at least partially contained within an interior space of the computer numerically controlled machine, an electromagnetic energy to cause a change in the material;
a source emitting the electromagnetic energy delivered by the head;
a sealed optical system comprising a housing and a plurality of optical elements enclosed in the housing, the plurality of optical elements including a first optical element and a second optical element oriented at a fixed angle relative to each other, the fixed angle having a magnitude configured to direct the electromagnetic energy from the source of the electromagnetic energy to the head; and
an adjustment mechanism configured to adjust a position and/or an orientation of the sealed optical system without changing the fixed angle between the first optical element and the second optical element, the adjustment mechanism comprising one or more pivots configured to rotate the sealed optical system in order to adjust a separation between the incoming beam of electromagnetic energy and the outgoing beam of electromagnetic energy.
2. The system of claim 1 , wherein the plurality of optical elements comprise at least one of a mirror and a lens.
3. The system of claim 1 , further comprising one or more spacers to achieve the fixed angle between the first optical element and the second optical element.
4. The system of claim 1 , wherein the first optical element and the second optical element are disposed in a mount formed from a housing of the sealed optical system.
5. The system of claim 1 , wherein the first optical element is mounted by at least one of welding, screwing, bolting, and gluing.
6. The system of claim 1 , wherein the head, the source of the electromagnetic energy, and the sealed optical system are coupled with a moving rail of the computer numerically controlled machine, and wherein the head, the source of the electromagnetic energy, and the sealed optical system are configured to move in tandem along the moving rail in order to minimize a length of a path of the electromagnetic energy between the source of the electromagnetic energy and the head.
7. The system of claim 1 , wherein the sealed optical system is associated with a first center of mass, wherein the first optical element is associated with a second center of mass, and wherein the first center of mass is aligned with the second center of mass.
8. The system of claim 7 , wherein the first center of mass is aligned with the second center of mass by at least including, in a mount housing the first optical element, one or more cutouts to minimize a weight of the mount.
9. The system of claim 1 , wherein the first optical element is housed in an elastic mount configured to minimize a mechanical stress against the sealed optical system.
10. The system of claim 1 , wherein the sealed optical system prevents the plurality of optical elements from being exposed to contaminants.
11. The system of claim 1 , wherein the one or more aperture windows are formed form a zinc selenide.
12. The system of claim 1 , wherein the magnitude of the fixed angle is further configured to cause the outgoing beam of electromagnetic energy to be substantially parallel to the incoming beam of electromagnetic energy.
13. The system of claim 1 , wherein the magnitude of the fixed angle is 90 degrees.
