摘要： PURPOSE:To obtain a diffraction grating which is advantageous in workmanship and has high energy efficiency by forming grooves to a combined shape of sloped parts and flat parts. CONSTITUTION:The grooves of the diffraction grating are formed to the shape combined with the faces inclined with respect to the reference plane of the grating and the faces (flat faces) which are flat to the reference plane of the grating and are continuous thereto. The ratio of the width between both is determined at 0.5-1.5 width of the flat faces with the width of the sloped faces as 1. The good energy efficiency is obtainable if the grooves are formed to the above-mentioned shape. Such groove shape has no sharp angled groove bases or steep ridge line parts at the tooth tips as compared to a typical saw tooth; therefore, the manufacture by a manufacturing process such as ion etching is easy.

摘要： PURPOSE:To highly precisely exchange a diffraction grating plate with a simple operation by disposing a plurality of diffraction gratings on a flat base plate so that the surfaces of all the diffraction gratings becomes the same plane. CONSTITUTION:A base plate 1 on which a diffrction grating 2 is fixed by an adhesive 3 is mounted on a spectroscope by a shaft vertical to the surface in such a manner as to be rotatable in the center of the base plate. The exchange of the diffraction grating 2 is conducted by this rotation. When the exchange of the diffraction grating 2 is conducted by this operation, the grating 2 can be moved parallel on the base plate flat surface and set in a determined position, and the mounting precision of the grating 2 on the base plate forms a spectroscopic precision when the grating 2 is exchanged and set in the determined position. Although the directional mounting precision of a grating ruled line generated at the time of mounting the grating 2 on the base plate 1 often reduces the spectroscopic precision, this can be solved by the direct formation of the grating 2 on the base plate 1, and the durability is also improved.

摘要： PURPOSE:To obtain a rotatory polarizer which is free from deviation between input light and exit light by constituting said polarizer of the junction of two parts. CONSTITUTION:The respective parts of a right triangular prism 4 made of a levo-rotatory crystal and a trapezoidal column 5 made of a dextro-rotatory crystal are so arranged that the horizontal right and left directions are in the optical axis direction of the crystals. The base BE of the prism 4 and the top (with AD as the base of the trapezium) EC of the column 5 are equal in length. The length of the base AD of the trapezium is twice the length of the top EC. The slant of the prism 4 and the slant of the column 5 are joined by an optical contact method without using any adhesive agent, and both are joined to the shape of a rectangular parallelopiped. When light is made incident as shown by an arrow from the AB of the two faces AB, CD sandwiching the joined surface AE, the light advances rectilinearly and emits from the face CD. Since both the levo-rotary and dextro-rotary crystals have an equal refractive index, no refraction arises even if the light passes through the face AE diagonally.
摘要翻译：目的：通过构成两部分的连接的所述偏振器，获得不会在输入光和出射光之间偏离的旋转偏振器。构成：由左旋旋转晶体制成的右三角棱镜4和由右旋晶体制成的梯形柱5的各个部分布置成水平左右方向在晶体的光轴方向上。柱5的基底BE和柱5的顶部（AD的梯形的底部）EC的长度相等。梯形底座AD的长度是顶部EC长度的两倍。棱镜4的倾斜度和柱5的倾斜度通过光学接触方法连接而不使用任何粘合剂，并且两者都被连接成长方体形的形状。当光线如箭头所示从两个面AB的AB（夹着接合表面AE的CD）入射时，光直线前进并从面CD发射。由于左旋旋转晶体和右旋旋转晶体都具有相等的折射率，即使光线对角地穿过面部AE，也不产生折射。

摘要： PURPOSE:To efficiently form a grating in a photoresist layer laid on a substrate by combinedly applying holography and ion etching in an oblique direction. CONSTITUTION:A photoresist layer 2 is laid on a substrate 1, and parallel lattice grooves 6 with a sine wave-shaped section are cut in the layer 2 by holography. The layer 2 is then irradiated with ion beams 4 at the angle of a direction which is obliquely upward to the grooves 6 and does not make a component projected on the lattice parallel to the grooves 6, e.g. at about 30 deg. angle of incidence to the substrate surface. The etching speed is maximized at about 60 deg. angle of incidence. Thus, the layer 2 is etched to form a grating (theta is a blaze angle) having lattice grooves 5 with an almost saw-toothed section.

摘要： PURPOSE:To form an optical element having a durable surface protective film causing no deterioration in the optical properties by applying a treating soln. contg. a silicon compound as a principal component to the surface of the light receiving part of the base material of an optical element. CONSTITUTION:A thin Al film 3 is formed on a glass substrate 2 by ordinary vacuum deposition. The resulting reflecting mirror body 4 composed of the substrate 4 and the Al film 3 is set on a spinner, and while rotating the body 4, a small amount of a soln. of a substance forming silicon dioxide such as about 5% silanol in ethanol is dropped on the surface of the body 4. After well evaporating the ethanol, the body 4 is put in a furnace and heated at 300 deg.C for about 1hr to obtain a silicon dioxide film 1 having 80-500nm thickness.

摘要： PURPOSE:To enhance diffraction efficiency in at least two or more wavelength regions by forming both side parts of the diffraction grating surface to the triangular groove of the angle differring from that of other faces and letting the central part of the diffraction grating face be a rotating axis. CONSTITUTION:The ray 5 incident to a certain state 1 of a diffraction grating is diffracted in the direction of 6 according to the optical rule of the diffraction grating. In the position 1 of the diffraction grating of a small incident angle, the ray is diffracted by the grating portion 3 (central region of the diffraction grating) but in the psoition 1' of a large angle of incident, it is diffracted even by the grating portions 2 on both side parts of the grating face. The diffraction efficiency of the grating portion 3 has the characteristics such as the curve 7 having blaze effect in short wavelength and the characteristics like the curve 8 having blaze effect on the long wavelength side and therefore if the center point 4 of the diffraction grating is inclined from 1 up to 1' with the central point 4 of the diffraction grating as a center, the diffraction efficiency may be enhanced in the wide wavelength region such as the curve 9 in which the curves 7 and 8 are combined.

摘要： PROBLEM TO BE SOLVED: To perform an accurate spectrometry by deciding an expansion coefficient of a groove function of a series expansion formula indicating a groove pattern of a diffraction grating, so that a value of the expansion coefficient of an optical path function representing a focus of a spectral optical system containing the grating becomes substantially '0' in a wavelength within a wavelength range of wavelength scanning. SOLUTION: When a rotary angle θ of a diffraction grating 3 is '0', a light from an inlet slit 1 is reflected by a concave mirror 2 converted into a converged light, incident to a plane diffraction grating 3, diffracted, and focused at an outlet slit 4. A groove function constitutes a part of an optical path relation representing a distance from a point on the groove of the grating 3 to a focus F' of a diffracted light. Then, in order that a focal distance of the light becomes as constant as possible irrespective of a wavelength, the focal distance γ' and the expansion coefficient in the groove function are decided so that an expansion coefficient of the optical path function representing the focus becomes '0'.
