Need electroformed copies of Fresnel lens
1996
RFQ: I am looking for a shop that can produce electroformed copies of a fresnel lens. The lenses have a 25 mm radius and the grooves are 0.2 mm deep.

A. Hi Guolin. Berl Stein is the guy I'd contact if I were you. He was recently employed by Fresnel Optics / Reflexite Technology, and is now president of NiCoForm [a finishing.com supporting advertiser].

RFQ: Dear Sirs,
For a job we are going to produce, we need 1000 fresnel lens 25.5 x 18 cm.(about).
We do not need particular enlargement.
If someone could help me giving directions, thank you in advance,

A. I run an electroforming facility which can create the electroforms for the fresnel optics. We duplicate very precise holographic microstructures with nickel process. These can be either hard or soft and thickness tolerances are within microns.
