In linear regression the standard least squares estimator performs a principal function and occasionally one may perhaps get the impact that it's the purely average and appropriate estimator on hand. still, there exists a number of alterna­ tives, proving necessary in particular occasions. objective and Scope. This publication goals at featuring a accomplished survey of alternative aspect estimation equipment in linear regression, in addition to the the­ oretical historical past on a complicated classes point.

Another technique is to make the entire system out of the same material. For an all-mirror system, this can be conveniently done, since metal mirror fabrication is now commonplace. Aluminum mirrors are often made by roughly shaping the mirror, chemically depositing nickel, and then polishing this surface to the desired figure. It is then vacuum coated with aluminum. For a lens system, making all the spacers out of Invar does not help, since the radii, lens thickness, and refractive index of the elements change with temperature.

Because they lie to the right of the glass line, they become positive lenses when used for secondary color correction. S-FPL53 is a relatively new material and it promises to be the most effective way to reduce secondary color. Its values of V and P are very close to those of CaF2. 55µm The Method of Lens Design 37 where λ is wavelength in microns, m is the absolute value of the magnification (equals 0 for objects at infinity), and f# is the ratio of focal length/entrance pupil diameter. This is the basis of the Raleigh criterion of resolution.

See the program Test Glass Fitting in Appendix E. Other designers have advocated a different technique. They try to fit the most sensitive radii first. The least sensitive radii they feel can always be fitted. Regardless of the method you choose, do not worry if you cannot fit every radius to the test list. If you fit most of them, you have still saved your client a substantial sum. MELT DATA FITTING Some lenses, particularly long-focal-length high-resolution types, are sensitive to small changes in refractive index and dispersion of the actual material used as compared to the nominal or catalog value.
