Abstract

Abstract

Ultraviolet detection technology is widely used in various fields of production and human life. It is thus greatly significant to study wide-spectrum ultraviolet (UV) imager systems. Through deducing the theoretical formula of chromatic aberration, a scheme for correcting the chromatic aberration of the optical system of the wide-spectrum UV imager with the lenses made of single material was proposed. Combined with the performance index of a high-sensitivity dynamic UV imaging detector, the optical system of the 210~400 nm wide-spectrum UV imager with only one lens material and all lenses being spherical was designed. The optical design software CODE V was used to optimize the system and evaluate the image quality. The results demonstrate that the Modulation Transfer Function (MTF) in the entire field of view and waveband of the system is better than 0.6 at the Nyquist frequency of 40 lp/mm and RMS<7.8 μm. Thus, the system has good imaging quality. The system does not contain aspheric optical elements, which makes it not only easy to process and assemble, but also reduces its cost and lays a technical foundation for the development of a wide-spectrum UV imaging spectrometer.
