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. This ...

200-kHz Swept Light Source for OCT Imaging

06/04/2013 NTT AT Advance Technology Corp. (NTT-AT) started selling a 1310nm-band wavelength swept light source for use in optical coherence tomography (OCT). OCT is a non-invasive in vivo imaging technique that widely used in clinical applications. This Wh...

How to Use the Zemax Black Box Surface

04/30/2013 The Zemax Black Box surface solves the problem of how to share optical design data without revealing design secrets. Sharing optical design data has previously presented many difficulties for optical designers and the organizations that employ the...

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...

How to Reduce Motor Size by Integrating Accurate, Low Cost Piezo Motors

01/02/2013 Today’s challenge is to make electronic applications smaller, cheaper and more accurate. PCBMotor builds accurate and high resolution, motors directly onto the PCB itself.  In addition to a world of new design opportunities, this new motor te...
