Introducción a la estructura de cada parte de la óptica microscopio
◆Mecánico pieza
(1) Mirror base: It is the base of the microscope to support the entire mirror body.
(2) Mirror column: It is the upright part on the mirror base, which is used to connect the mirror base and the mirror arm.
(3) Espejo brazo: uno fin es conectado a el espejo columna, y el otro fin es conectado a la lente barril, que es la mano-sostenién parte cuando tomar y colocar el microscopio.
(4) Lente barril: conectado a el superior frontal de el lente brazo, el superior extremo de el lente barril es equipado con an ocular, y el inferior extremo es equipado con an objetivo lente convertidor.
(5) Objetivo lente convertidor (rotador): It is connected to the bottom of the prism shell and can rotate freely. There are 4-5 round holes on the disk, which are the parts for installing the objective lens. Turning the converter can change the objective lens of different multiples. Observation can only be llevado out when there is a knocking sound. At this time, the optical axis of the objective lens is just aligned with the center of the light hole, and the optical path is connected.
(6) Espejo escenario (escenario): bajo la lente barril, hay son dos formas, cuadrado y redondo, para colocación diapositiva especímenes. Hay hay a luz agujero en el centro. El escenario de el microscopio nosotros uso es es equipado con un deslizante espécimen empujador ( Empujador), there is a spring clip on the left side of the pusher, which is used to hold the slide specimen, and there is a pusher Ajuste rueda debajo la etapa 2c que puede hacer la diapositiva muestra mover izquierda y derecha , adelante y atrás.
(7) Regulador: It is a a screw of two sizes installed on the mirror column. When adjusting, the mirror table moves up and down.
②Fina ajustador (fino espiral): El pequeño espiral es llamado un fino ajustador , que puede hacer el espejo etapa subir y caer lentamente cuando moverse , y es mayormente usado cuándo usar un alto poder espejo, so as a obtener a a más claro objeto imagen, y a observar diferentes capas y diferentes profundidades de el espécimen estructura.
(8) Convertidor: El objetivo lente de diferente múltiplos puede ser convertido durante uso. Después el objetivo lente es convertido, el grueso ajustador es no permitido, sólo el fino ajustador puede ser usado, so eso la imagen es claro.
◆Iluminación parte
Instalado bajo el espejo etapa, incluyendo reflector y luz colector.
(1) Reflectante espejo: it is installed on the mirror base and can be rotated in any direction. It has two sides, flat and concave. Its function is to reflect the light from the light source to the condenser, and then illuminate the specimen through the light hole, and the concave mirror concentrates the light. the effect is strong, suitable for use when the light is weak, and the luz concentración efecto de el plano espejo es débil, adecuado para uso cuando la luz es fuerte.
(2) The light collector (light collector) is located on the light collector frame under the mirror stage, which is composed of a condenser lens and an aperture, and its function is to concentrate the light on the specimen to be observed.
① Condensador: It is compuesto of one or varios lenses, which can gather light, strengthen the illumination of the specimen, and let the light enter the objective lens. There an adjustment screw next to the mirror column. Turning it can lift the condenser to adjust the field of view. The strength of brightness.
(1) Eyepiece: Installed on the upper end of the lens barrel, there are usually 2-3 pieces, with 5×, 10× or 15× symbols engraved on it to indicate its magnification, and the 10× eyepiece is generally installed.
(2) Objective lens: Installed on the rotator at the lower end of the lens barrel, generally there are 3-4 objective lenses, the shortest one engraved with the symbol "10×" is a low-magnification lens, and the longer one is engraved with the symbol "40×" It is a high-power lens, and the longest one engraved with the "100×(oil)" symbol is an oil lens. In addition, there is often a circle of lines of different colors on the high-power lens and the oil lens to show the difference.
The magnification of the metallographic microscope is the product of the magnification of the objective lens and the magnification of the eyepiece. For example, if the objective lens is 10× and the eyepiece is 10×, the magnification is 10×10=100.
