摘要： An optical device used for converging a light beam on a signal recording surface of an optical disc includes an optical lens for converging the light beam on a signal recording surface of the optical disc and a light barrier portion provided on a surface of the optical lens facing the optical disc. The light barrier portion includes a light transmitting aperture through which is transmitted the light beam converged by the optical lens. The light beam illuminated on the optical disc has its diameter controlled by this light transmitting aperture. The light radiated by a light source so as to be incident to the optical device is converged by the optical lens. The light converged by the optical lens is transmitted through the light transmitting aperture and illuminated on the signal recording surface of the optical disc. The diameter of the light beam illuminated on the signal recording surface of the optical disc is controlled by the light transmitting aperture, and thus the numerical aperture NA of the optical device is determined.

摘要： A single focus telescopic lens includes, in order from the object side: a diaphragm stop; and first and second lens components, each lens component being of positive refractive power and each having a convex surface on the object side near the optical axis. Each of the two lens components has two aspheric surfaces, may be a lens element, and preferably is made of plastic. The single focus telescopic lens may include no other lens elements and the diaphragm stop may be on the object side of the single focus telescopic lens. A specified on-axis condition is satisfied in order to reduce aberrations and to make the single focus telescopic lens compact. Additionally, satisfying a condition related to the maximum angle of incidence of among all the image forming principal rays helps achieve the desired telescopic properties with the desired optical performance.

摘要： A lens shapes a diverging laser diode beam, and particularly circularizes and collimates, or diverges, or converges the beam. The lens may be part of an optical system, or part of a laser diode assembly. The lens is constituted of a body, the opposite ends of which are spaced from each other. The surfaces of the ends may be toric with the toric centers being coincident with the optical axis. The surfaces also have curvature profiles which circularize and collimates, or diverges, or converges collimates the beam. The curvature profile of one of the first and second surfaces has a correction profile which is a function of Zernike polynomials, thereby reducing wavefront error of the beam exiting the lens. The correction profile is also a function of the offset of the laser diode from the optical axis (misalignment), thereby increasing the misalignment tolerances for beam to lens centering. The curvature profiles of the surfaces may have correction for astigmatism in the beam shape produced by the laser diode. The body of the lens is a single body which may be composed of a single element, or multiple elements integrated into the single body.
摘要翻译： A透镜形成发散的激光二极管光束，并且特别地使光束圆化并准直或发散或会聚。 透镜可以是光学系统的一部分，或激光二极管组件的一部分。 透镜由相对端彼此间隔开的主体构成。 端面的表面可以是复曲面的，复曲面中心与光轴重合。 这些表面还具有圆形化和准直，或发散或收敛的弯曲轮廓。 第一和第二表面中的一个的曲率分布具有作为泽尔尼克多项式的函数的校正曲线，从而减少离开透镜的光束的波前误差。 校正曲线也是激光二极管与光轴的偏移（未对准）的函数，从而增加了光束对透镜对中的不对准公差。 表面的曲率分布可以校正由激光二极管产生的束形状中的散光。 透镜的主体是单个主体，其可以由单个元件或集成到单个主体中的多个元件组成。

摘要： An optical element for microscopic inspection of a surface. The optical element has an elongated body defining an optical axis, with a first end adjacent the surface and a second end directed toward an imaging instrument. The body has a curved reflective surface and an optical aperture at the first end, and defines first and second associated focal points on the optical axis. The first focal point is spaced apart from the first end of the body, such that positioning the surface at the first focal point generates an image of the surface at the second focal point. The reflective surface may be paraboloidal, with a concentrating lens focusing collimated rays to the second focal point, so that a conventional microscope may view the image generated at the second point.
