Customized Large Optics by Avantier: Meeting Unique Needs with Precision and Quality In the ever-evolving world of optical technology, the demand for customized large optics has been on the rise. Many customers seek tailored solutions to meet their specific requirements, which often cannot be met with off-the-shelf products. Avantier, a leading name in the field of custom optical solutions, recently undertook a challenging project that exemplifies our commitment to excellence. Customer’s Unique Needs A customer approached Avantier with a specific set of needs that could not be fulfilled by readily available stock optics. They required 400mm large prisms for an application in which they exposed red, green, and blue lasers into the prisms and recorded holograms. Additionally, the customer required 250mm and 400mm diameter off-axis parabolic (OAP) mirrors for research and development studies in their laboratory. The need for these large optics was driven by the distinct nature of their projects and the unavailability of suitable off-the-shelf components.
