Fused silica lenses for F-Theta Lenses

Fused silica lenses for F-Theta Lenses
Product Description
Fused silica has a low refractive index than the most other optical glass
materials, but it is the ideal material for the High-Power fiber lasers demand.
In order to achieve minimum focal shift, large and uniform scan field. Most F-
Theta Lenses needs meniscus lenses and the shaped like a hemisphere, keep good
surface quality, centering and irregular is hard work. CLZ Precision Optics is
a well-known manufacturer of the optical dome, rich experience in the
manufacture of hemispherical optical components. Manufacturing meniscus lenses
for use in F-Theta Lenses, CLZ Precision Optics can control the centering less
than 20 seconds when the lens' diameter is more than 50mm, surface quality is
better than 20-10, and irregular can be meet 0.5 fringes or better.
