This invention is an anti-glare device comprising a flexible, soft material that is rolled as a sleeve to be wrapped around, while projecting from an end of an objective lens housing such as is found on telescopic scopes, spotting scopes, binoculars, cameras and video cameras to prevent sun glare on the lens or lenses of such devices regardless of the angle of the sun rays otherwise engaging such lens or lenses.

A method for forming a metallic mirror surface on a receiving surface is shown. The method comprises the steps of: cleaning the underlay surface; spraying on the receiving surface an activating treatment agent solution wherein the activating treatment agent solution contains a hydrochloric acid solution including about 10 cc to about 44 cc of hydrochloric acid, about 1.5 g to about 5 g of stannous chloride and about 0.001 g to about 0.005 g of a precious metal salt of at least one of a silver ni...

Disclosed is an antiglare film having excellent durability. The antiglare film is disposed on the front of a display device and comprises a transparent plastic film and, formed on the transparent plastic film, at least an antiglare layer having fine concaves and convexes on its surface, wherein the antiglare layer is formed of a transparent resin and satisfies requirements that: (1) the surface of the antiglare layer has a three-dimensional ten-point mean roughness of 0.9 .mu.m to 3 .mu.m; and (...

A diffusing film comprises a transparent resin in which scatterers are dispersed. The difference between the refractive index of the transparent resin and that of the scatterers is in the range of 0.04 to 1.5. The scatterers are flat particles having sizes of 0.1 to 50 .mu.m.

An illumination optical apparatus (8) includes a light source (10) and light conducting system (L) that conducts a light beam (14) from the light source to an object (M) such as a mask having a pattern, to be irradiated. A light-attenuating member (18) or other light-intensity controlling member, such as filter, for controlling the intensity of the light beam is arranged in the optical path between the light source and light conducting system. Also disclosed is a method for manufacturing semicon...

An optical element has a plurality of reflecting regions for reflecting light in succession, each of the plurality of reflecting regions comprises a curved surface, at least two of the reflecting regions has a common reflecting surface, and the optical paths of the light defined by the plurality of reflecting regions intersect with one another.

An illuminating apparatus for a microscope comprises a condenser lens for condensing beams of illumination light from a light source and a pin-hole stop. The pin-hole stop has a pin-hole, provided on an optical axis, for transmitting only strong light beams from a central portion of the light source among the illumination light beams condensed by the condenser lens. The pin-hole stop also has a light reducing/illumination area, disposed around the pin-hole in symmetry with respect to the optical...

Antireflection multilayer coatings with only three or four layers are proposed for the production of laser resistant optical components with minimal residual reflection and high transparency for UV light in a wavelength range approx. 150 nm to approx. 250 nm at large angles of incidence in the range of approx. 70.degree. to approx. 80.degree., particularly in the range between approx. 72.degree. and approx. 76.degree.. For incident p-polarized UV light three-layer systems can be used, in which a...
