Übersetzung für "Langwellig" in Englisch

In particular, they must be largely free from impurities which absorb long wavelengths.

The emission is at a relatively long wavelength and has a high blue-green component.

This is transferred via energy transfer to the acceptor, which then emits at a long wavelength.

Also being long wave they are vulnerable to local interference.

Compared with the peryleneimide dyes, the fluorescence of the peryleneamidines of the formula VII has been shifted to longer wavelengths.

By blending the bis-benzothiazole-pentamethine-cyanine dye according to the present invention, which dye sensitizes in the long-wave red spectral region, with dyes that sensitize only in the short-wave red spectral region, the entire red region can be sensitized comparatively uniformly and without a pronounced peak, while maintaining a gap in the green region of the spectrum. A good utilization of the red fraction of the exposure lamp up to the infrared region is thus ensured, while the gap in the green region makes it possible to process and visually control the recording material under bright safelights, for example, green safelights.

Compounds, such as those described, e g., by Becker, possess at normal temperatures (5°-40° C.) not only in solution, but also in polydiethyleneglycolbisallylcarbonate, a plastic material often utilized for ophthalmic lenses, such a fast inverse reaction that the equilibrium concentrations attainable with natural illumination strengths (10-100 klux) of the longwave-absorbing form are too small to produce preceivable darkening, respectively a change in color.

The absorption edge is usually shifted somewhat towards the long wave compared with products that were obtained according to the previously known process using the same metal compounds.

The bifluorophoric and trifluorophoric colourants usually have a pronounced fluorescence in solution (fluorescence quantum yield of almost 100%), which is likewise usually shifted to longer wavelengths and consequently can be differentiated from the fluorescence of perylene dyes.

Compounds of the formula I are very light-fast dyes which show strong fluorescence in solution and whose fluorescence occurs at a longer wavelength than that of the bisimides (perylene dyes).

Here "long wave" is to be understood as a wavelength range in which the light energy fundamentally corresponds to the band edge of the relevant photoconductive material.

They fluoresce at long wavelengths with a good colour stability and can be prepared in good yields from compounds of general formulae (IIa) and (IIb) and appropriate coupling components.

By blending the bis-benzothiazole-pentamethine-cyanine dye according to the present invention, which dye sensitizes in the long-wave red spectral region, with dyes that sensitize only in the short-wave red spectral region, the entire red region can be sensitized comparatively uniformly and without a pronounced peak, while maintaining a gap in the green region of the spectrum.

In apolar solvents, such as dioxane for example, pyridinium-N-phenol betaines for example absorb in the long-wave region, whilst in polar solvents, such as methanol for example, they absorb in the short-wave region.

Upon binding to HSA, the excitation maximum is longwave shifted so the dye is more efficiently excited by the laser line.

Comparison Examples (1) and (2) have a markedly lower specific extinction. In contrast, although comparison Example 3 has a high specific extinction it is at too high a wavelength, so that the important range 320-340 nm is not completely covered.

The 6 UV LEDs with a 365nm (long-wave) wavelength for determining the fluorescence can also be used in bright environments and in daylight.

Thus, the milky area of the graphical element 6 may fluoresce in a long-wave range, for example orange, and the clear area of the light-collecting sheet 12 in the short-wave range, such as, for example, green.

It was merely observed that the absorption and fluorescence maxima of some dyes undergo a shift to longer wavelengths by 10 nm on average.

A slight twist of the patterns or, respectively, gratings against each other results in a moiré transversely to the desired moiré; this, however, is “long-wave” and thus not interfering.

They are spectrally shifted toward the excitation wavelength both to long wavelengths (Stokes range) and to shorter wavelengths (anti-Stokes range).

As described above, the use of long-wave-emitting polymethine fluorescence dyes for organ diagnostics is already known, and therefore also of ICG for example.

The region 102 is divided as follows from long-wave to short-wave: a region 108 for infrared radiation, especially near infrared radiation, a region 110 for red visible light, a region 112 for orange visible light, a region 113 for yellow visible light, a region 114 for green visible light, a region 116 blue visible light, a region 118 for violet visible light, and a region 120 for near ultraviolet radiation.

However, the X-ray fluorescence radiation of these elements is relatively long-wave and is therefore absorbed not only by detector windows, but is absorbed strongly by a few centimeters of air already.

Such defects, caused or not rectified by production machines for example, are generally of long wavelength, for which reason the spectrogram curve 17 deviates from spectrogram curve 16 especially in an area 18 .
