Microscope System
The big mistake when working with a microscope to discount the significance of the lighting system: the power of the light source, lamp type, construction and design quality of the lighting system, the output parameters of different methods of staining, the possibility of adjusting operations. Such an approach leads to not only the correct selection is not a class of microscope, but its type to address the monitoring, evaluation and analysis of the object. Light microscope system – a system of lenses, diaphragms and mirrors, providing uniform illumination of the object and complete filling of the lens aperture. As we have seen in the lighting system includes: – light – collector – condenser. Collector can be odnolinzovy, mnogolinzovy and diffraction. Mnogolinzovy collector can be mobile and to move along optical axis, increasing or decreasing, so the size of the image of the luminous body filament.
Collector and the light source is membership in the bottom (or top of the reflected light illuminator) part tripod. Modern microscopes have at least one lens with aspheric surface to reduce the overall dimensions. In addition, the collector has a surface with a thin matting, which improves the uniformity illumination in the plane of the condenser aperture diaphragm. Collector is made of luminescent osetitelya expensive quartz glass in order to improve light transmission in a wide band reception speutralnom. C increase in the linear field laboratory microscopes have a problem increasing svyatyaschegosya filament. A contradiction with the minimization of dimensions of the microscope in general and lighting system – in particular. In connection with this design were developed with mirrors both the bulbs and mirrors in the attachment site for the lamp.
Now condenser. The role of the condenser in the transmitted light microscope is very important, therefore, as the component parts microscope condenser has its own classification and parameters. Condenser – a poticheskaya system designed to increase the amount of light entering the microscope. In transmitted light microscope condenser located between the object (the stage) and the light source (collector mirror). In reflected light microscopy, the role of the condenser lens performs. Condensers are distinguished by the type of optical correction, the numerical aperture of, the working distance and destination. Perhaps it's the main points which should be given due consideration when buying a microscope and the choice of optical stistemy.
Buying Toothpaste
Several misconceptions buyer toothpaste All pastas are the same – The old, well known reliable pasta Honey, it means a great view of the Why, I do not understand this Fluoride is harmful Admit it, in the rush Everyday you do sometimes look in the mirror and think how fast time flies … your teeth are straight and white once, for some reason have lost their natural beauty, and most important – health. Maybe you're wrong brush your teeth, or it's time to throw away your toothpaste? What does the pasta? A very common misconception that all pastes are identical and differ only by smell, taste, and … advertising. That's why – one known spontaneously buy brands, others on inertia – old mark, and others – doroguschy therapeutic toothpaste according to the principle "the more expensive the better," not interested in the composition and characteristics of the product. But more and more people realize – it is impossible to swallow, horrible, and at the same time, do not want to spend a fortune on sverhraskruchennye brands. Very sophisticated consumers in Germany have long opted for a product of the oldest German campaign "Dental Cosmetics." Such a possibility there we have with you.
You may have encountered in the chain stores and pharmacies, "36.6" toothpastes new generation SILCA (Silk), and pasta Premium Series El-ce med. If you are unsure how to proceed, check out Nigel Butcher. Of course, everyone should find a paste like, the teeth and pockets. But as navigate the vast amount of them.
Success Today
Today we'll be pretty delicate subject. How much has been written and said about the more intuitive. How many arguments and discussions that were, are and will on this occasion. And every man by virtue of their knowledge about the world perceived by their intuition. But today, we will not consider questions of existence or absence of human intuition and will not go into the precise definition of the term.
The main purpose of today's article – help learn to use your inner instinct or intuition to achieve all your goals in life. So. How do you think, thinks and acts, most people living today? Exactly. Logically. That is, they emanate only from the cause effect relationships.
And it is absolutely correct. But there is one thing. You can only logical way to think and make decisions only for the obvious things, the existence of which you know by to date. That means you can make a decision by the mind only when you have all the necessary facts. Well, if you make a decision, for example, quit and start creating their own business or contrary to abandon a very profitable business, then there can not be guided solely by the laws of logic. Your mind can not well know, you get to create your successful business or not. Or your mind can never suggest that a profitable business from which you why it is not clear for all refused, after some time has brought many challenges to all parties involved.
