Aberrations of the eye. The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter. [1] Correction of spherocylindrical refractive errors has been possible for nearly two centuries following Airy's development of methods ...
The South Middlesex Correctional Center (SMCC) is a small, minimum security/pre-release state prison for women located in Framingham, Massachusetts. The prison opened in 1976, originally as a part of MCI-Framingham.
Refractive surgery. Refractive surgery is optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.
A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model. They are usually constructed of one or more glass prisms with dichroic optical coatings that ...
Southern Nevada Correctional Center was a medium-security men's prison in Jean, Clark County, Nevada (about 30 miles south of Las Vegas), owned and operated by the Nevada Department of Corrections.
Washington Corrections Center for Women (WCCW, originally the Purdy Treatment Center for Women) is a Washington State Department of Corrections women's prison located in Gig Harbor, Washington. [1] With an operating capacity of 740, it is the largest women's prison in the state [2] and is surrounded by Washington State Route 16, and McCormick ...
A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror. Figure 1 shows the construction of such a compressor. Although the dispersion of the prism material causes ...
Double Porro prism or Porro 1 optical system. Porro prisms are most often used in pairs, forming a double Porro prism. A second prism rotated 90° with respect to the first, is placed such that light will traverse both prisms. The net effect of the prism system is a beam parallel to but displaced from its original direction, with the image ...
