About Fresnel lenses
Fresnel lenses, though virtually flat, can act as spherical lenses. Fresnel lenses offer tremendous space and weight saving capabilities, and also enable focal lengths shorter than their aperture, a feat impossible with spherical lenses.
Fresnel lenses are widely used for camera field lenses, OHP condenser lenses, and rear projection screens.
NTKJ manufactures and sells not only off-the-shelf Fresnel lenses, but also manufactures custom-made Fresnel lens products according to our customers’ exact size and design requirements. Please contact us for more details.
