GRASP OAS
GRASP OAS
The GRASP Optics Assembly System (OAS) is designed for precision alignment and process technology in assembling small products with micrometer accuracy. It is suitable for clean room environments and can be adapted for standalone, semi-automated, or fully automated production lines, capable of producing up to 10 million products annually.
Production Stages
- OAS.P.x: Prototyping and sample production during product and process development.
- OAS.M.x: Mid-volume production with sequential processing.
- OAS.H.x: High-volume production with parallel processing.
Key Processes
- Active alignment
- Pre-alignment processes including cleaning, particle inspection, and gap control
- Camera, lens, LiDAR, and sensor assembly
- Precision adhesive dispensing and pre-curing
Active Alignment Specifications
- 5 degrees of freedom in alignment
- Actuator unidirectional repeatability: X and Y: ±0.15 μm, Z: ±0.06 μm, θX and θY: ±2 μrad
- Typical lens back focal length: 1 – 30 mm
- Field of view: 40° - 180°
- Product interface: MIPI, GMSL2, FPD link, GigE
- Wavelength: VIS or (N)IR
Key Benefits
- Scalability from low to high volume production
- Shorter cycle times by separating UV pre-cure from active alignment
- High-quality assembly with lower total cost of ownership
- Higher yields and reduced component costs due to less stringent geometric accuracy requirements
Performance Analysis
The document includes performance graphs showing improvements in image sharpness and alignment precision before and after the active alignment process. The active alignment ensures optimal positioning of camera parts, enhancing image quality and projection.

Workstation Specifications ACTIVE ALIGNMENT High quality assembly made easier and faster with lower total cost of ownership. The major advantage of active alignment is achieving very high product performance, while individual components do not need to be extremely geometrically accurate. With the help of active alignment, the optics are placed in the best position according to the image -quality, -projection. Higher yields can be achieved than compared to geometrical or mechanical alignment. Component cost can be reduced as these do not need excessive accuracy. KEY BENEFIT 1 Active alignment...

Workstation Specifications ACTIVE ALIGNMENT Multiple targets are projected from a set (virtual) focus distance on the chip. The sharpness of the image is measured at several relative lens-chip positions. Based on these measurements the algorithm determines the optimum position and orientation of the lens relative to the chip, resulting in an optimal aligned camera assembly.
