One of the early promises of Holographic technology was to use a hologram or an HOE to guide and control the light from a lighting fixture. Technically there were challenges to overcome, such as the suppression of spectral dispersion and elimination of zero order from the lamp. In terms of manufacturing, a process for high fidelity mass replication from holographic masters had to be realized as well. The resulting manufactured holographic material would also need to be affordable, durable and last up to 20 years in the field. Such technical and environmental challenges have not traditionally been a concern for material produced within the mass production arm of the existing holographic industry.
