Fresnel lense
Fresnel-lensing ,optical glass ,achromatic doublet lens ,led lens,spherical lens
Effect:
Compared with traditional spherical lenses of the same focal length ,fresnel lens has the advantages of lighter weight and thinner center while eliminating spherical aberration and improving the utilization of energy of light. The lens is suitable for replacing a special lens such as big-diameter lens.
Specification:
