Positive Fresnel lenses are designed for light management, with SC 236 having a focal length of 72.5 mm, a clear aperture of 101.3 mm, and a thickness of 1.8 mm. The lens is optimized for infinite conjugate on the plano side and has a facet spacing of 0.279 mm. All models in this series are fabricated from PMMA with a standard refractive index of 1.49 and a standard thickness of 1.8 mm, unless otherwise specified.
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.
