However, a projector-like optical system ( i. e., using condenser lenses for illumination, with a viewing lens in place of the projection lens ), employing daylight ( not direct sunlight ) for the light source, can produce comparably excellent visual results -- although for only one viewer at a time -- without the unacceptable hazards of actual projection.

However, in lenses, dispersion causes chromatic aberration, an undesired effect that may degrade images in microscopes, telescopes and photographic objectives.

However, scrutiny with modern telescopic lenses reveals that the buildings are mere concrete shells lacking window glass or even interior rooms, with the building lights turned on and off at set times and the empty sidewalks swept by a skeleton crew of caretakers in an effort to preserve the illusion of activity.

However, larger amounts may be corrected with convex lenses in eyeglasses or contact lenses.

However, it is well known that he was not the first to make achromatic lenses.

However, eye charts are useful in deciding whether the patients need eyeglasses or contact lenses to correct their distance vision, and assessing how effective their refractive correction is.

However, since wide-angle lenses have a wider field of view, they are generally used from closer, while telephoto lenses have a narrower field of view and are generally used from farther away.

However, Einstein was only considering the chance of observing Einstein rings produced by stars, which is low ; however, the chance of observing those produced by larger lenses such as galaxies or black holes is higher since the angular size of an Einstein ring increases with the mass of the lens.

However, in the next round, played under TV lighting Reardon suffered a drying of contact lenses and lost 5 – 2 to David Roe, having led 2 – 1.

However, if water vapor gets between the layers of the lens, condensation can occur between the lenses and is almost impossible to get rid of ; thus, properly constructed and maintained dual-layer lenses should be air-tight to prevent water vapor from getting in between the lenses.

However, a song can be broken down into its component parts by separating the words from the tune, just as a microscope can have its lenses prised from the tube with pliers.

However, this exacerbating effect is not generally believed to exist in the general case, although in cases where the myopia is due to accommodative spasm, removing the corrective lenses for a time may lead to improvement.

However, just as all the buildings have not fallen and flowed back to their original mud, so the values which wanted them and saw that they were built have not all disappeared.

However, his subject matter and basic themes have remained surprisingly consistent, and these, together with certain key poetic images, may be traced through all his work, including the new jazz experiments.

However, only Illinois, Oregon, Louisiana and Rhode Island have a situation in which the sundry units of government vary widely in relation to fiscal uniformity.

However, the aircraft which we have today are tied to large, `` soft '' airfields.

However, first I thoughtfully study my sketch for improvement of color and design along the lines I have described.

However, whether you arrange to have a European or American model, if you rent a car with the proper seating capacity in relation to the number of people in your party, your transportation expense will average very close to $10.00 per day per passenger.

However, it is not known to either the union or the public precisely how much of a cost increase is caused by a given change in the basic wage rate, although the companies are presumed to have reliable estimates of this magnitude.

However, the Attorney General of California, at the request of the Secretary of Labor, sought to have the jurisdiction over the issue removed to the Federal District Court, on grounds that it was predominantly a Federal issue since the validity of the Secretary's Regulation was being challenged.

However, as we have seen, in later childhood the child begins to substitute the standards of the peer group for those of parents and teachers.

However, by cultivating a wine dealer and accepting his advice, one will soon enough ascertain whether he has any knowledge of wines ( as opposed to what he may have been told by salesmen and promoters ) and, better yet, whether he has a taste for wine.

However, in the same three-month period, toll-road bonds, as a group, have bucked this trend.

However much we may have to criticize liberal theology's constructive formulations, the theology we ourselves must strive to formulate can only go beyond liberalism, not behind it.

However well chosen and cleverly arranged, such memorabilia unfortunately amounted to more of an interruption than an auxiliary to the evening's main business, which ( considering the talent at hand ) should probably have been the gathering of fresh samples of the Chicago style.

However, certain critical interlocutory court orders, such as the denial of a request for an interim injunction, or an order holding a person in contempt of court, can be appealed immediately although the case may otherwise not have been fully disposed of.

However, wall depictions of this instrument have not been discovered, casting some doubt over the extent to which this instrument was used.

Experiments have been conducted to attempt the synthesis of ununennium ( Uue ), which is likely to be the next member of the group, but they have all met with failure .< ref name =" link "> However, ununennium may not be an alkali metal due to relativistic effects, which are predicted to have a large influence on the chemical properties of superheavy elements.

However, advancements in robotic technology have allowed the design of functional and realistic humanoid robots.

However, several telescope manufacturers have recently developed telescope systems that are calibrated with the use of built-in GPS, decreasing the time it takes to set up a telescope at the start of an observing session.
