MOHLSTRASSE 22. CALL NUMBER 413921/22 XEROX CORPORATION, Rochester, V.T. 14603, V.St.A. Symmetrically split Dagor lens especially for

the copier diffraction

The invention relates to a symmetrically divided Dagor lens, in particular for the production of copies, with an aperture of at most 4.5 and a magnification factor of 1 to 1.6, with a correction of spherical and ohromatic defects including secondary colors, lateral and longitudinal color dispersion, coma, astigmatism, Distortion and curvature of field.

In reproduction machines, in which light images of the originals to be reproduced are projected onto a light-sensitive recording plate in order to make a copy of the respective To produce originals, a lens is required which focuses a light image on the recording plate and The properties of known lenses for Kopleraasohinen such as the nooh acceptable aperture angle, the degree of resolution and other factors largely depend on the strength of the lens It is generally known that with decreasing solder strength steel the overall performance of a lens for a photocopier drops considerably if the aperture angle remains constant. Of-

half of the lenses used in copier machines have apertures in the range from 6.3 to 11, in order to achieve a good resolution with a reasonable opening angle within one to guarantee a wide spectral range and to produce images of acceptable quality «.

With the development of color copiers, in which light rays with wavelengths distributed in the visible spectrum are passed through the lens, a problem arises with known lenses due to a chromatic error, which is also known as secondary color offset by a small amount from each other when they fall on the image plane. This displacement causes image deterioration, particularly in the reproduction of color originals, when the displacement reaches values that can be distinguished with the eye. Also, many lenses are used in copier machines to enlarge or create an image that is the same size as the original. This is done by using a first optic with a magnification of 1x1 and a second optic that creates an enlarged image. The respective system can then be switched selectively between the object and the image plane, the other one not being used only work with different magnifications, but such flexibility is at the expense of image quality, so that it has little value in a reproduction device with a high image quality and limited light intensity.

The object of the invention is to provide an improved

10981 1/1589

ObjectIt especially to create copies, which has a maximum aperture of 4.5 and the generation of good quality color images with light wavelengths between 3900 and 6500 Angstroms. In particular, such a lens should be easy to manufacture and set up.

a) a front composite optics with lenses I, II and III between the object plane and the diaphragm,

b) a rear composite optics with lenses IV, V and YI between the diaphragm and the image plane, wherein

In Fig. 1 a symmetrically divided Dagor objective is shown between the object plane and the image plane. It contains two composite optics each with three lens elements, a diaphragm is arranged between the two composite optics The front part of the lens lies between the object plane and the diaphragm and its rear part swisohea the diaphragm and the image plane »the eeohe lenses are such arranged that the entire objective besuglloh the diaphragm is constructed symmetrically

The front part of the lens contains one lens I with po-

positive magnification, a lens II with negative magnification and a lens III with positive magnification © Die . Lenses I and II are cemented together with a transparent optical cement; one of the from the Eastman Kodak Company, Rochester, New York, “Preferably the putty should be a Have a refractive index that is pretty much the same as that of lenses I and II o The lens III, that of the diaphragm is assigned closest, is separated from the lens II by an air space

Any known optical glass can be used for the lenses of the objective. Suitable types of glass are, for example, Dense Barium Crown (SK-18), Light Flint (LF-1, LF-6) and barium flint (BAF-9) from Schott Optical Glass Company, Duryea, Pennsylvania. Lenses IV, V and VI of the posterior Composite optics have the same configuration as lenses III, II and I and are arranged accordingly

Since the lenses I and II and V and VI are cemented to each other, the entire lens can be manufactured more easily and more precisely than when there is an air space between these lenses would be present. The undesirable accumulation of tolerances of a multi-lens lens that is duroh Air spaces are separated from each other is also small with the objective according to the invention, since x two air spaces are avoided »

In addition to cementing certain lenses to one another, there is a mechanical advantage in that the lenses II and III and the lenses IV and V are in edge contact with one _{another.The air spaces S 2} and S ₅ and nine cloths of the outdoor barrier are very sensitive Maintained within a rather low tolerance range, the tangential

The field curvature of the field is drastically impaired. Ba is the curvature of the lenses, i.e. the distance between the optical Aohee from the apex to the one running through the idnsenkante Level, can be kept within narrow tolerances much more easily than a spacing β element provided between two lenses, is a better setting of the existing one Air spaces possible · The edge contact enables smaller Manufacturing costs as well as a better yield of usable lenses in the manufacture «^

In Fig. 1 the front composite optics old a double-convex lens I, a double-concave lens II and a convex-concave lens III is shown. The dimensions, shapes and the radii of curvature of the lenses are shown for explanation purposes only and do not correspond to the actual values. For example, lens I could be a convex-concave lens as long as its magnification remains positive. The other lenses of the objectives can experience similar changes, The same applies to the rear composite optics

The lens according to the invention is designed such that it lends itself well to color copying because the othromatic defect known as secondary color Jj is reduced. In Figs. 2a-d graphical representations of the secondary color effects of the objective according to the invention are shown · In all representations let on the ordinate the light wavelength between 4500 and 6500 Angstroms plotted · The abscissa of Figures 2a and 2b shows the actual height of the axial upper ray for aperture 0.7 in the axis-parallel image plane according to FIG an aoheen-parallel ray in primary light of 5500 angetröm in millimeters, while the abecissa of FIGS. 2o and 2d the actual height of the upper tangential ray for aperture 0.7 with a full object compared to the main ray , in millimeters shows «The main ray is defined as the-

that ray of the object position with full field of view that runs through the center of the aperture »Figures 2a and 2c apply to magnification 1: 1, Figures 2b and 2d for magnification 1: 1.6 · In all representations the value X_ is a measure for the secondary color and can be taken from them in the form of the length of a line drawn from the point of the primary wavelength perpendicular to the line connecting the secondary and tertiary wavelength points. These measurements show that from the center of the image to the outer edge of the image, the secondary color for both end values of the magnification range is below 0.01 mm. The amount X "of the secondary color is therefore so low with an objective according to the invention at both ends of the magnification range that only very little image deterioration occurs due to this error A luminous intensity of 4 _f 5 can be used with good results and is corrected for spherical errors, coma, astigmatism, distortion and field curvature

The lens can work with two specific magnification values of 1: 1 and 1: 1.6, but there are also all intermediate - values possible with consistently good performance. The objective is arranged approximately in the middle between the image and the object plane and then works with a magnification 1: 1, If a magnification of 1: 1.6 is desired, it is moved closer to the object plane, while the image plane moves away from the object plane by a distance as shown in the following table III is listed. With regard to the reliable quality of the images generated with both settings, a and the same lens can be used for both magnification values by simply moving it and the image plane receives a different setting compared to the object level.
