- Generate baseline reference optical designs in Zemax or similar software for further design and fabrication by external vendors.
- Simulate laser parameters with Zemax or relevant software.
- Select appropriate components including, sensors, displays, optical stabilization systems, and lenses, and lasers to meet program requirements.
- Interpret stray light analysis and generate specific design recommendations for baffles, coatings, stops, etc., to minimize stray light in systems. Laboratory Optical Characterization
- Maintain and utilize an optical laboratory to support development, testing, and prototyping efforts, including equipment such as integrating spheres, collimators, optical alignment stations for centration and tip/tilt, and more.
- Characterize performance of EOIR sensors, typically broadband focal plane array type.
- Test and validate delivered optical assemblies to ensure compliance with specifications and requirements.
- Design new tests and test stations and construct laboratory apparatus as needed to support program test and validation requirements. Prototype Integration
- Build and integrate EOIR prototype subsystems, including cameras, optics, and lasers.
- Perform precise alignment and boresighting of optical components and sub-assemblies in multi-aperture multi-band and imaging and laser systems. Transition to Manufacturing
- Generate technical documentation and reports.
- Provide optical subject matter expertise to program managers and manufacturing staff. Assist in creating manufacturing work instructions.
- Transition relevant fabrication or test benches from the prototyping to manufacturing environments.
Required
Qualifications:- Bachelor's degree in optical engineering or closely related field 10+ years of experience in imaging and laser optical design, including: Specifying EOIR and imaging sensor optical components
