Übersetzung für "Optisch dicht" in Englisch

In the normal case, a light-impermeable plastic will be selected, so that the housing is optically tight.

The flexible, cloth-like and optically dense material can convince in the most different applications.

The substrate (303) is optically dense in FIGS. 3 a) to 3 d).

The layers are optically dense and the material can be wetted completely in >30 seconds.

A part of the star's outer atmosphere becomes optically thick due to partial ionization of certain elements.

To make the housing optically tight, a second outer housing is provided that completely surrounds the first housing.

This glass plate, made of K5, for example, is provided on the side facing toward the specimen with an electrically conductive yet optically transparent layer; on all of its other exposed surfaces it is metal-coated so as to be optically opaque.

This high-purity aluminium layer is optically dense, about 50 to 80 nm thick and has a total reflection of more than 91% in the visible light range.

FIG. 5 shows an arrangement with an optical correction element 7.1 in the form of a translucent solid body with an optical density higher than air, and advantageously with an optical density approximately equal to that of the material of the container.

Transparent originals (film strips) are often optically dense, so that there is not sufficient light available for a spectrophotometric evaluation.

The retaining member is visually tight, seen in the axial direction, also with three lamellas, so that even dropping wax or condensate is unable to enter the external ear canal but is caught by the lamellas.

Due to the fact that the at least two lamellas are disposed opposite from each other in the interior space, the retaining member, seen in the axial direction, is visually tight so that even dropping condensate or dropping wax is caught by the lamellas.

It is thus ensured that, on the one hand, the lamellas overlap in such a way that the retaining member, seen in the axial direction, is visually tight, so that no condensate or wax is able to enter into the external ear canal, and that on the other hand, the retaining member is provided with a sufficient passage of air.

As can be seen from the drawn-in center line 9, the lamellas 4, 5, 6 respectively protrude over the center line 9, i.e. the lamellas 4, 5, 6 overlap, seen in the axial direction, so that the retaining member is configured to be visually tight, seen in the axial direction.

Consequently a two-level system or optical medium that is optically dense relative to the emission wavelength is preferred.

The light source according to the invention can then preferably be operated in thermodynamic equilibrium, which is supported by the use of at least one two-level system that is optically dense at the emission wavelength and therefore causes reabsorption of the emitted photons.

In FIGS. 1 a) and 1 d) to 1 k), the substrate (103) is optically dense, in FIG. 1 b) it is optically transparent.

The substrate (203) is optically dense in FIG. 2 a), optically transparent in FIG. 2 b).

In FIG. 2 c), the upper substrate (205) is optically dense, the lower substrate (204) optically transparent.

Another measure to avoid leakage radiation in the environment of the bending die or the die arrangement is, to embody the interfaces between the adjacent beam leading elements, in particular between bending dies abutting against one another or between an external radiation source and a bending die of a die arrangement optically dense.

The walls or bases are preferably “visually closed” and each have a continuous, compact construction.

To be able to ensure the high transmission in the visible spectral range, the silver layers used must be very thin (<50 nm), i.e. they are by no means optically dense.

By the layer combination according to the invention, a diffusion of metal atoms from the reflector layer into the substrate which would cause the reflector layer to no longer be optically dense is furthermore prevented.

In case the reflector layer is initially at least twice as thick as the anodization layer, it was observed that the thickness of the remaining reflector layer is sufficient to be optically dense and therefore has no significant loss of reflection.

WO 2007/095876A1 refers to an adhesive layer that is applied on the anodization layer before a first functional reflector layer having a thickness <90 nm is applied, which is not optically dense.

This can be, for example, be tubes with an inside mirror coating which are optically closed at both ends.

This layer must have a thickness that makes the layer “optically dense”, thereby preventing incident radiation from penetrating through the layer and reaching the underlying layers and thus potentially causing interference effects in the aluminum oxide layer.
