- 6X Laser Beam Expander
Client Need:
Client needed a 6X beam expander that could provide the specified beam quality and spot size and to minimize wave front distortion of the transmitted beam.
3-D Engineering Solution:
3-D Engineering used the existing optical design but eliminated variations in the manufacture of the optics and mechanical components to demonstrate significant improvements in performance. The development approach for this project was divided into two phases: the first phase was an evaluation study, the second phase was the redesign development phase that included the fabrication and evaluation testing of (2) units to be delivered and integrated into existing systems.
Results:
3-D Engineering performed all design detail activities as required to fully develop the 6X Beam Expander. This activity included all detailed parts/features, specifications, assemblies, test requirements, and documentation creations. 3-D Engineering successfully manufactured working units, performed validation testing on the units, and provided on-site integration and system level evaluation and testing.
- Infrared Cold Camera Shutter
Client needed a "Cold Camera Shutter" system developed to provide a means to make true "In-Situ" radiometric measurements to provide the ability to detect plume exhaust. The project utilized an IR imaging camera containing precision optics and sensors packaged within a cryogenically cooled (LN2) vessel.
3-D Engineering Solution:
3-D Engineering Corporation performed a thorough review of existing packaging design and identified all relevant specifications and requirements, specifically: size constraints, thermal requirements (temperature extremes and thermal insulation requirements) and shutter interface/interaction requirements and conducted a study of all off-the-shelf shutters and shutter mechanisms in general, examining electrical and mechanical methods of shutter actuation including contact and non-contact design approaches.
Results:
3-D Engineering successfully integrated a reliable cryogenically cooled “Cold Shutter” into the assembly that facilitated zero radiance calibration and thereby optimized the performance of the camera system and recorded test data from performing the initial prototype testing.
- Hand Held Directional Reflectometer
Client Need:
Client needed to design a Hand-Held Directional Reflectometer (HHDR) to make rapid in situ measurements of the infrared (IR) reflection properties of materials in field environments.
3-D Engineering Solution:
3-D Engineering was responsible for the development, testing and delivery of prototype and production level units that successfully met all design and performance objectives which included: Illumination by a broad-band infrared beam at a user-established angle of incidence, directing an ellipsoidal mirror and lens combination onto an IR imaging focal plane array (FPA), establishing a method to ascertain the detector response, interpret a quantitative measurement of the angular distribution of the reflected light, calculating the angular distribution of reflectance and determining the total reflectance, etc.
Results:
All elements of the project were successfully executed and delivered by 3-D Engineering on schedule, within budget and in accordance with the Statement of Work.
- Gem Microscope
Client Need:
Client needed an improved microscope that would provide reliable functionality and ergonomics.
3-D Engineering Solution:
3-D Engineering redesigned the existing microscope and designed new lighting systems for improved functionality and ergonomics of the existing microscope.
Results:
3-D Engineering successfully integrated a reliable gem microscope to be utilized by the customer.
- External OPuS Mirrior Purge
Client Need:
Client has optics assembly that exhibits poor optical performance when used in high power/high duty cycle conditions. This is a result of thermal effects from heating at the mirrors used to delay the laser pulse in a confocal resonator.
3-D Engineering Solution:
3-D Engineering conducted analysis and developed an interim design solution to provide a laminar purge system for the mirrors.
Results:
3-D Engineering performed an interim purge design effort that included analysis for purge flow, mechanical design for newly designed purge components, and fabrication of components.
- RTATS Optical Scanning Mirrior
Client Need:
Client needed 3-D Engineering to conduct analysis and studies to establish the suitability of the existing RTATS design (strengths and weakness) relative to its intended application of a high speed optical scanning system.
3-D Engineering Solution:
3-D Engineering established the Strengths and Weakness of the existing RTATS optical scanning mirror assembly design as suited to the high speed scanning operational criteria and proposed/suggested change recommendations that would enhance the system performance to meet the high speed scanning operational criteria.
Results:
3-D Engineering performed all analysis and tests and delivered all the criteria within the stated milestone dates.
