the lens includes spherical, aspheric and cylindrical lenses, with the
anti-reflection and high-reflection coating covered on the surface. And
the substrates are optional, including N-BK7, UV fused sllica, K9 and
can offer different kinds of lens upon your requests.
lens has better curvature radius and the curvature radius changes with
central axis, which can maintain good aberration correction, improve the
optical quality and reduce the optical element.
CNI use high
precision milling and polishing equipment to
ensure better surface profile, and provide Zygo
