Cyclo Olefin Polymer (COP), which was developed by Zeon Corporation, is well known and used as an optical plastic
in optical markets, having unique properties such as high light transmission, low water absorption, low birefringence
etc. Optes Inc, who is ZEON CORPORATION's affiliate optical parts manufacturer, has succeeded in the development
of high performance optical base films. These are used for retardation and polarizing films in LCD's (Liquid Crystal
Displays), made from Cyclo Olefin Polymer with own film extrusion technologies. The Optical base film developed by
Optes Inc has superior properties compared with those of existing products such as polycarbonate (PC), polyethylene
terephthalate (PET) and Triacetate Cellulose (TAC) base in terms of low birefringence, high optical isotropy and high
dimensional stability under high humidity and temperature conditions.
Zeon Corporation developed quite new optical plastic Cyclo Olefin Polymer; COP(ZEONEX) with own technology in 1990 then started sales for ZEONEX for optical application with its very unique properties such as low birefringence, low water absorption, high glass-transition temperature 136 °C and high light transmission etc. Currently, ZEONEX is well known in optical market and used widely as optical plastic for pick up lens and other many kinds of optical parts for laser beam printer and digital camera. Addition to those ZEONEX grades, in last year, Zeon Corporation developed a new ZEONEX grade called ZEONEX340R, which was designed for blue laser devices requiring more severe specification. ZEONEX340R has high transmission at 405nm which is used laser wavelength for Blu-ray Disk / HD-DVD as well as enough durability under exposure of 405nm laser, addition to those new properties, keeps other optical properties such as low birefringence and very low water absorption.
We report broadband monolithic transmitters and receivers ICs for mm-wave electromagnetic network measurements. The ICs use non-linear transmission lines (NLTL) and sampling circuits as picosecond pulse generators and detectors. Combining NLTLs and sampling circuits with monolithic broadband antennas, the pulse can be radiated and received for free-space measurements. In this paper, we demonstrate a variety of measurements include high-Q Bragg filters showing high frequency resolution (10 dB/GHz slope at 118 GHz), and phase-frequency measurements of quartz samples to determine the dielectric constant.
