High-speed KTN Vari-focal Lens
06/04/2013
KTN is a transparent optical crystal composed of potassium, tantalum, niobium, and oxygen. The first KTN crystal was synthesized in the 1950's and is well known as a crystal with a very large quadratic electro-optic effect (Kerr effect), which det...

KTN Laser Beam Deflector
06/04/2013
The KTN beam deflector has advantages in its high speed operation. When it is operated at high frequencies, however, the optical beams are not only deflected but also converged due to a lens power generated in the KTN crystal via Gauss law.

Life Sciences - Zemax Models of the Human Eye
03/27/2013
There have been literally dozens of eye models published over more than 150 years,
from very simple “reduced” eyes consisting of a single refracting surface to very
complex models with more than 4,000 refracting surfaces. Some models have a
gradie...
