To improve the fidelity of nanostructures in transfer process a composite stamp with reasonable hardness distribution in 184 PDMS used to nanoimprint was studied. The stamp is composed of a stiff 184 PDMS structured layer and a soft 184 PDMS supporter layer. We studied the relationship between the hardness of the 184 PDMS and the proportion of each component in 184 PDMS. The appropriate components proportions of prepolymer and curing agent corresponding to the different region of the composite stamp were presented. The fabrication method of the stamp is also presented. Corresponding experiments were carried out by using this stamp. Kinds of nanostructures were transferred in one inch diameter area with good fidelity. The feature sizes of the structures were less than 100 nm. 2012 IEEE.

In order to get enough information about the target avoid big chromatic aberration as a result of wide spectrum and the complexity of optical system and adapt different special environment temperature a hybrid refractive/harmonic diffractive optical system in far-infrared multi-band is described in the paper. This diffractive optical system has been designed an athermalized multi-band imaging system with harmonic diffractive element in 15-50m spectrum based on larger 1dispersion capability and particular thermal dispersive power of harmonic diffractive element. Then at the temperature range from 0C to 40C this design can simultaneously meet with all requirements of the imaging system in five harmonic wave bands including15.8-16.2m 18.5-20m 23-25m 30.5-33.5m and 46-50m. In each harmonic wave band the magnification changes as a function of wavelength which creates image registration error. To compensate this shortcoming a zoom optical system is designed with three lenses by means of optical two- component method. The design results show that the hybrid refractive/harmonic diffractive optical system can realize athermalized and achromatic design and the zoom optical system makes half image height at 3.53mm in every harmonic wave band and still realizes aberration compensation action. In the five harmonic wave bands each optical transfer function approaches the diffraction limit at ambient temperature range of 0C to 40C. Finally the system realizes the requirements of portability mini-type and ease for fabrication. 2009 SPIE.
