Optical system manufacturing and alignment system
View Patent ↗An optical component manipulation system has two opposed jaws, which can each be independently positioned relative to each other in a coordinate plane to thereby effect the desired positioning of optical components within the larger system. Z-axis rigidity is provided by air-bearings. Laser heating of the jaws is used for solder, or similar heat driven bonding, processes.
1. An optical component manipulation system, comprising:
an optical component that has been bonded to an optical bench;
first and second opposed jaws for cooperatively engaging the optical component;
a first x-axis position detection system for detecting an x-axis position of the first jaw;
a first y-axis position detection system for detecting a y-axis position of the first jaw;
a second x-axis position detection system for detecting an x-axis position of the second jaw;
a second y-axis position detection system for detecting a y-axis position of the second jaw;
a first x-axis actuator for positioning the first jaw along the x-axis;
a first y-axis actuator for positioning the first jaw along the y-axis;
a second x-axis actuator for positioning the second jaw along the x-axis; and
a second y-axis actuator for positioning the second jaw along the y-axis.
2. An optical component manipulation system as claimed in claim 1 , wherein the first and second jaws are adapted to engage the optical component.
3. An optical component manipulation system as claimed in claim 1 , further comprising first and second stages, to which the respective jaws, position detection systems, and actuators are attached.
4. An optical component manipulation system as described in claim 1 , further comprising a jaw heater for heating at least one of the first and second jaws and thereby the optical component held byte jaws.
5. An optical component manipulation system as described in claim 4 , wherein the jaw heater comprises a laser device that irradiates at least one of the jaws.
6. An optical component manipulation system as described in claim 1 , further comprising a jaw heater for heating at least one of the first and second jaws and thereby the optical component held by the jaws to a solder melting temperature to bond the optical component to the optical bench.
7. An optical component manipulation system as described in claim 1 , further comprising a control system for driving the first x-axis actuator, the first y-axis actuator, the second x-axis actuator, and the second y-axis actuator to position each of the first and second jaws and thereby an optical element of the optical component.
8. An optical component manipulation system as described in claim 7 , wherein the control system drives the first x-axis actuator, the first y-axis actuator, the second x-axis actuator, and the second y-axis actuator in response to position information from each of the first x-axis position detection system, the first y-axis position detection system, the second x-axis position detection system, and the second y-axis position.
9. An optical component manipulation system as described in claim 1 , wherein the jaws extend downward to engage the optical component from above.
10. An optical component manipulation system as claimed in claim 1 , further comprising first and second stages, to which the respective jaws are attached, the stages being supported by respective y-axis suspension systems.
11. An optical component manipulation system as described in claim 1 , wherein each of the first and second, x-and y-actuators comprises a voice coil system.
12. An optical component manipulation system as described in claim 1 , wherein each of the first and second, x-and y-position detection system comprises an optical encoder and grating.
13. An optical component manipulation system as described in claim 1 , further comprising a substrate stage for positioning a substrate in a direction that is orthogonal to the x-axis and the y-axis.
