摘要： This invention relates to a microscope objective lens system a part of which is immersed in a liquid to observe a sample present in the liquid. Particularly, this invention provides an apochromat-grade microscope objective lens system which can be machined cheaply and easily by the conventional technology, which is well corrected for chromatic aberration, and which is excellent in flatness of the image plane. This objective lens system has a plane-parallel plate on the most sample side, is constructed without using an embedded lens as used in the conventional objectives, and can take a variety of lens layouts.

摘要： In a configuration constituted by two lens sheets, the ranges of levels of refractive index n and Abbe number .nu. of the image-side lens made of a biconvex lens are specified in order to realize an imaging lens constituted by two lens sheets which can attain a long back focus, a relatively wide angle of view, a high brightness, a small size, and a lower manufacturing cost. The imaging lens comprises, successively disposed from the object side to the image side, a concave lens and a biconvex lens, while at least one surface of the concave lens is an aspheric surface. Also, assuming that the refractive index and Abbe number of the biconvex lens are respectively n and .nu., the following conditional expressions (1) and (2): 1.55.ltoreq.n (1) 35.ltoreq..nu. (2) are satisfied.

摘要： A wide angle lens is made of three groups so as to satisfy a predetermined conditional expression concerning abbe number, thereby making it telecentric and yielding no eclipse in its peripheral luminous flux. Also, an apparatus accommodating it is made compact as a whole. This wide angle lens comprises, arranged in the following order from the screen side toward the liquid crystal side, a first lens group composed of a concave lens (L1), whose concave surface having a large radius of curvature is directed toward a smaller conjugate side (liquid crystal panel), and a convex lens (L2); a second lens group composed of one concave lens (L3) and two convex lenses (L4) and (L5); and a third lens group composed of a Fresnel lens (L6) which is disposed near a liquid crystal panel (L7; 4). The abbe number .nu. 1 of the lens L1 which is the concave lens in the first lens group is 57.8, whereas the abbe number .nu. 2 of the lens (L3) which is the concave lens in the second lens group is 25.4, thereby satisfying the conditional expression of .nu. 1>.nu. 2. The focal length f1 of the first lens group is 453.1 mm, whereas the focal length f0 of the whole lens group system is 67.76 mm, thereby satisfying .vertline.f1.vertline.>f0.

摘要： An optical transmitter including a light source for outputting a carrier light, an electro-absorption optical modulator for absorbing the carrier light according to an applied voltage to thereby output an intensity-modulated signal light, a device for applying an offset voltage to the optical modulator so that the applied voltage enters a region where the generation of the carrier light in the light source is stable, and a device for receiving an input signal to superimpose a modulation signal corresponding to the input signal on the offset voltage. This optical transmitter prevents wavelength chirping of the light source due to residual reflection in the optical modulator to thereby allow improvement in waveform.
