TL;DR: In this article, a method of glass selection for apochromatic optical systems with reduced chromatic aberration is presented based on the glass maps by using a glass database (Schott glass) and an optical design program (OSLO) to help the optical designer to select optical glass types in more efficient way.
Abstract: Apochromatic designs of lens systems utilizing two optical materials are described. A method of glass selection for apochromatic optical systems with reduced chromatic aberration is present. This method is based on the glass maps by using a glass database (Schott glass) and an optical design program (OSLO) to help the optical designer to select optical glass types in a more efficient way. 'Active' glass maps can be used to compare glasses for special properties and to change glasses in the optical design process , and then using computer program(OSLO) to aid in the design of a lens and the validation results. The goal for this paper is to make glass selection easier to understand.
TL;DR: A digital camera with two prism arrays is applied to capture a stereo image of the corrected chromatic aberration and distortion, and the camera distortion can be increased, and reduced by the lens optimization.
Abstract: We apply a digital camera with two prism arrays to capture a stereo image of the corrected chromatic aberration and
distortion. The doublet prisms are used to correct chromatic aberration. The camera distortion with two prism arrays can
be increased, and reduced by the lens optimization.

TL;DR: In this paper, the dispersion of the ocular liquids was measured in the Pulfrich refractometer for five different wavelengths and the distribution of the refractive index within the crystalline lens was approximated by the parabolic function.
Abstract: In this paper we studied the chromatic properties of the bovine eye. Dispersion of the ocular liquids was measured in the Pulfrich refractometer. The measurements was done for five different wavelengths. From this data the dispersion curves and Abbe number of the eye substances was derived. To measure the distribution of the refractive index within the crystalline lens we modified the Pulfrich refractometer. Gradient of the refractive index of the crystalline lens was measured for three wavelengths. Distribution of the refractive index within the crystalline lens was be approximated by the parabolic function. Additionally, we measured the spherical aberration of the bovine crystalline lens for four different wavelengths. The experiment showed, that crystalline lens is corrected for the spherical aberration.
