Positive Fresnel lenses are designed for light management in applications such as collimation or focusing. The SC 922 is a plano Fresnel lens with a focal length of 698.6 mm, a clear aperture of 615.7 mm, and a thickness of 2.5 mm, optimized for 546 nm light in PMMA material. The lens is specified for infinite conjugate on the Fresnel side and finite conjugate on the plano side. The standard thickness for this series is 1.8 mm, but 2.5 mm is available as an option for certain models including this one.
Positive Fresnel Lenses can be designed as a collimator, collector or with finite conjugates. They are usually corrected for spherical aberration.
The designs can be trimmed according to customer requirements (within limits of clear aperture). It is possible to combine a Fresnel lens structure with other structures like diffusers or microlens arrays in the same part through double-sided structuring. Optical coatings for increased efficiency are possible.
