DigiLens, Inc. is a leader in waveguide diffractive optic technology and nano-materials, serving the aerospace, automotive, government and consumer electronics industries. We develop unique optical solutions for organizations, performing “optical origami” on some of the most challenging displays and imaging applications. We are also a Switchable Bragg Gratings (SBG) research company, one of the first pioneers.
Aside compact planar form-factor, DigiLens’ waveguides have a suite of advantages that go to the heart of life-cycle cost, which includes a lower cost of development, procurement, installation and maintenance.
First, component costs are reduced. The optical complexity is contained in the various holographic optical elements. Once the non-recurring engineering (NRE) costs associated with creating the masters is complete, the replication costs are relatively insignificant compared to the traditional recurring material costs associated with the components.
Second, assembly time is reduced. Not only is part count lowered, but the assembly process is quicker. The planar structures are cost-effective and laminated together with high-precision using fiducials. The touch labor is reduced compared to that of building an optical piece-part assembly to exacting standards. In addition to the precision of waveguide alignment, the holographic layers are more tolerant of minute variations.
Third, quality is higher. One of the biggest challenges in designing a new precision optical system is controlling the roll-up of tolerances on the piece parts, the mechanical housings and the final assembly process. With holographic optical waveguide elements, “gold-standard” masters are produced and handed over to the manufacturer to replicate with the same high standard of quality. The net result is a much greater yield of devices at a lower price point and shorter cycle time.
