Description

l Illuminator for the microscope. The utility model relates to the field of physics, in particular, to means for illuminating objects of observation in microcopes. The utility model can be used in clinical and biochemical laboratories for the study of objects in transmitted light with lenses of small and medium magnification. The closest in technical essence and the achieved result, selected as a prototype, is a simplified illuminator for a microscope - OI-32 Technical description and user manual Simplified lighter. A type. LOMO, Zak. No. 5937, 2S.06.78, technical description and instruction manual for biological microscopes, Type. LOMO, Zak. No. 5777, May 22. g., p. 24). Simplified light for a microscope consists of a metal case, a frame with a collector and a cartridge with a lamp. The optical scheme of the illuminator consists of an incandescent lamp, a collector, which is a scattering lens, and a matte stack, which is placed on the onpaiy collector during research. The cartridge with the lamp can be moved in the housing and clamped in the desired position by a screw in order to achieve the most intense illumination of the drug. A disadvantage of the known illuminator is that its body, made of metal, is quite heavy and expensive. The use of complex expensive diffuser lenses in the illuminator does not help to reduce its cost and complicates the process of lighting adjustment. In addition to this, the use of a P1220 - I5PI4 incandescent lamp (220 V, i5 W) as a light source does not provide sufficient illumination of the working field, and also leads to quick heating of the microscope and the studied samples, which reduces the accuracy of the research results. Remember 20011О0951 мпк 7, ео2 в 2t ;; eWPP P | iill MO of this, the incandescent lamp is short-lived and not electrically safe.

The task solved by the utility model is the improvement of the illuminator for the microscope.

The technical result from the use of the utility model is to increase the accuracy of research results, reduce cost, increase durability and electrical safety.

This is achieved by the fact that in the illuminator for a microscope containing a power supply, a power cord, a housing and a light source fixed in the housing, the housing is made in the form of a plastic cylinder, on the upper part of which there is a fixing washer with frosted glass fixed in it, in the niche there is a regulator brightness, and a silicon emitter is used as a light source.

In FIG. I shows a illuminator for a microscope; FIG. 2 microscope condenser with illuminator.

The illuminator A for the microscope consists of a power supply I, a power cord 2, a housing 3. The housing 3 is made in the form of a plastic cylinder, on the upper part of which a fixing washer 4 is mounted with frosted glass fixed in it 5. Inside the housing 3, in the lower part, is installed dimmer 6, the handle 7 of which is brought out. The brightness regulator 6 is connected inside the housing 3 to the board 8 of the power supply circuit of the silicon emitter 9. The silicon emitter 9 (LED) is a silicon crystal. The displaced 1 board 8 of the power supply circuit, which is installed inside the case 3 under the frosted glass 5

Illumination of the studied samples in the microscope with illuminator A is as follows.

and fixed in it using the fixing washer 4. Using the power supply I and the power cord 2, the illuminator A is connected to an alternating current network, voltage 220 V, frequency 50 Hz with output voltage 12 V, which reduces power consumption and ensures high electrical safety at work with a microscope. When the illuminator A is connected to the network, voltage ionization of the electron-hole structure of crystal 10 of the silicon emitter 9 occurs and it begins to glow with cold light, which excludes heating of the microscope and the samples under investigation. Frosted glass 5, glued into the fixing washer, ensures the dispersion of the light flux, which contributes to the creation of optimal Illumination of the entire working field, and this leads to increased accuracy of the research results. The brightness of the light is adjusted using the knob 7 of the dimmer 6 by turning left to right. The execution of the housing 3 of the illuminator A from plastic does not require the use of other materials, which leads to a reduction in cost, and the use of a silicon emitter (LED) as a light source contributes to its durability.

The housing 3 of the illuminator A is made of plastic, for example, polystyrene. As a light source in the silicon emitter 9 uses a silicon crystal Yu - Ga In Jf. As a power supply I, for example, a step-down transformer is used.

Thus, the use of a utility model leads to an increase in the accuracy of research results, lower costs, increased durability and electrical safety.
