NoIR LaserShields are the product of engineering innovation and tight manufacturing tolerances, providing an optimal balance between protection and visibility.

Self-emission: The straylight level, received at the defined detector element location of the PLM/FPU straylight model by self emission (with "cold" stops in front of PACS and SPIRE instrument detectors), excluding the self emission of the telescope reflectors alone (but including any other contributor, notably the M2 hexapod), shall be < 10% of the background induced by self-emission of the telescope reflectors.

The HSC created a dedicated working group to study the straylight efffects on the Herschel operations. New models based on the 'as built' optical system were prepared and observations were made to verify the models (see Figure 4.13 for examples of model and observational reality). Improvements in stray light checking in mission planning were made during operations and all cases of possible conflicts were verified manually by the Spacecraft Environment Scientist; where there was found to be a significant danger of degradation of the quality of an observation due to straylight it was re-scheduled for a later epoch. In a few cases late in the mission, when there was no possibility of re-scheduling an observation potentially affected by straylight, it was accepted that such observations had to be scheduled on a "now or never" basis, with a date for execution being choosen that minimised the effects of straylight, provided that the observations was of a point source and that its scientific quality would not be significantly degraded.

The Silhouette Wall Light by Ross Gardam provides up-light or downlight to interior spaces, featuring a gently fluted shade in glass or anodised finish.

Scattered light from sources outside the telescope FoV: Taking into account the worst possible combination of the positions of the Moon and the Earth w.r.t. the line of sight (LoS) of the telescope, the extreme values are: Sun-S/C-Earth angle of 37°Sun-S/C-Moon angle of 47°Sun-S/C-LoS angle of 60°.8 to 119°.2 (in the S/C XZ plane)Maximum roll angle of ±1° The straylight will be < 1% of background radiation induced by the self-emission of the telescope.

One of the key elements that will guide your decision is obviously the amount of light that will be provided by the fixture, as well as its materials and construction. At the time of incandescent bulbs, everything was simple: Review the wattage and light output and make your decision based on that. However, now incandescent bulbs are prohibited because they waste a lot of energy. Meanwhile, technological advances in LED lamps in recent years have led to the adoption of a new standard: the lumen. To get an idea of this relationship, an incandescent 60W bulb provides about 700 lumens, a 40W, 400 lumens. Today, the ratio in lumens and watts depends on the technology used; low-energy bulbs, halogens, or LEDs all have different outputs. There are also energy labels to help you choose the most economical alternative. At ' . $storeName . ', you can discover all of the possible light bulb options, but in most cases opt for LED lighting to ensure a minimum Class A fixture.

Light wave complexity is a description of the saturation level (or length) of light waves. Each single pure wavelength of light is considered a saturated level.

Sources inside the FoV: over the entire FoV at angular distances ≥ 3 arcmin from the peak of the point-spread-function (PSF), the straylight shall be < 1 × 10-4 of PSF peak irradiance (in addition to level given by diffraction).

The Herschel design was carried out including the instrument optical layout. This approach allowed the level of straylight that originates from the various sources at detector level to be provided directly. Therefore, the straylight requirements were given directly as the straylight reaching the detector. The following apply over the full operational wavelength range:

We have given special attention to the usability of our site. The categories help direct you to quickly find the type of lamp you want, whether it is downlights, floor lamps, or other indoor light fixtures. To further facilitate your search, we have also separated out our lights by room. Looking for a hanging light to highlight your dining room table? Check out our dining room lights.

To make it even easier, we have also improved our search filters, and we have a team of 5 people dedicated to recording all the lighting characteristics of the lights that we sell online.

Despite the care we've given to our descriptions, you may still have questions. Our professional consultants are there to answer all your questions and help you choose the light that fits your needs, and your budget. Feel free to use our online request form, or you can also reach us by phone on weekdays at the number listed below. We are located in Cologne in Germany, but there will always be someone available to answer you in English. A technical team is ready to solve any malfunction or offer advice in case of problems. Also note that there is a two-year warranty on defects for our entire assortment of products.

The Ingress Protection (IP) rating is always accompanied by two digits. The first indicates the protection against solid foreign objects into the light, the second refers to protection against water. It is better to opt for lamps with a minimum IP44 rating for bathroom lighting or outdoor lighting. An IP20 rating is sufficient to ensure that children cannot access the electrical parts of the light. Meanwhile, energy labels are shortened to a letter grade according to their energy consumption efficiency, from A++ (very efficient) to E (very inefficient). With the output of lumens remaining equal, a class A light will consume much less energy than a class D light. It is therefore a great help for your purchasing decision because it can significantly reduce the long-term costs of your light. Outdoor lights with sensors also grant substantial savings and are less of a nuisance for the neighbourhood. They only light up when necessary and most are adjustable, both for their light duration and for the sensory angle. Find outdoor sensors and other practical products in our accessories section.

According to current straylight analysis for the orbit configuration of Herschel (see [RD3]), for sources outside the FoV, the straylight radiation is within specification, except for small locations on the sky, where radiation reflected from rectangular hexapod structures can enter the instruments directly. These small locations exist primarily for the Moon. Only two minor paths were found which could be applicable also to the Earth. For the worst-case locations of the Moon, the specification is exceeded by a factor 16.4.

Figure 4.13. Comparison of straylight optical models produced by M. Ferlet (priv. comm.) and observational results. In the top row, a Herschel observation has been planned with Jupiter in position 'I', while in the bottom row the Moon has been placed in position 'F'. In both cases, there is a very good agreement between the model prediction and the straylight results.

You also have probably noticed varying shades of colour for different light bulbs. These colours generally range from a very warm and yellow appearance, to some very cold, white-bluish lights, like in some car headlights for example. These colour values are measured in Kelvin. The higher the value, the colder the light will look. The conventional warm-white that is found in the majority of fixtures for the general public has a value around 2,700 Kelvin. From 6,000 Kelvin and upwards are the cool whites, which are often used in office and commercial lighting, while between 6,000 and 3,500 Kelvin is the neutral white light range. A candle with a value of approximately 1,000 Kelvin is an example of warm light.
