Large Fresnel Lens
Screen, large Phil pinch lens
Our company is improving our skills and systems of Diamond Turning Machine for
large size Fresnel lens.
We are one of world leading company of mold and large Fresnel lens. Base on
this technical advantage, we develop lenses for concentration, solar oven, integral
photonics and magnifier.
Normal type Fresnel lens such as magnifiers, lighting equipment, 3D display is being used in a variety of areas.
CPV type Fresnel Lens has Groove on the opposite side for condending.
(A flat surface condensing)
Also we design to use more 3mm Optical PMMA for loner life time and to have 0.5 ~ 1.0mm groove pitch for higher solar concentration.
(If groove pitch is density, then quality of image that is maginifed is clearer.If groove pitch is width, then efficince of concentration of light is higher.)
