Learning microscope with digital camera and adjustable backlight

General description of a learning microscope with a digital camera and adjustable illuminance

A learning microscope with a digital camera and adjustable backlight with a wide range of accessories is the perfect microscope for beginners. As a gift, the whole set of accessories is very suitable for young people whose parents want to arouse curiosity after research and early learning. Also, the teaching microscope with attached tools can be used in sciences such as biology, botany, education, philately (collection and study of postage and tax stamps) and entomology (study of insects and other arthropods). The teaching microscope and associated accessories are manufactured in accordance with the certificate, which prescribes quality management systems in accordance with the requirements of the ISO 9001 standard.

The teaching microscope has the unique property that a Barlow lens is inserted into a monocolar tube. The Barlow lens has a millimeter scale from 0 to 45 mm inscribed on the side with an accuracy of 2.5 mm. By precisely pulling out and retracting the lens, the observed object can be magnified up to twice. In addition to the Barlow lens, the teaching microscope also has a rotating revolver with three lens slots, on which a four-fold magnification lens, a ten-fold magnification lens, and a forty-fold magnification lens are mounted. In conjunction with the two added wide-field interchangeable eyepieces in a tube (wide-angle eyepiece) WF10x with tenx magnification and WF16x with 16x magnification, the observed objects can be observed during microscopy with a minimum magnification of 40x and a maximum magnification of 1280x.

Both added wide-field eyepieces have added protective boxes with caps, which can be closed during non-use to prevent damage. The rotating revolver with three locations for the lenses allows you to quickly change the magnification, and comfortable work with the microscope, as it is not necessary to store the lenses. Nevertheless, unscrewing and replacing an individual lens on a revolver is easy. The monocolar tube is tilted by 45 degrees and rotated by 360 degrees, which simplifies use, as any movement of the microscope during work and thus movement of the object is not required. While no eyepiece is inserted into the microscope tube, it is protected by a plug-in cap that prevents unwanted particles from entering.

Adjusting the sharpness during the observation of the object, under high magnifications, is done with two large macrometer screws with which we move exactly up and down the 90 x 90 mm table on which the observed object is. The microscope table has two self-adjusting holding grips for holding the slide. Adequate illumination of the observed object is prepared by two light-emitting diodes with a multi-stage wheel for adjusting the light intensity. The first LED illuminates the pattern from the side, thus adding a reflective light. The second LED illuminates the sample from below, thus adding a translucent illumination of the sample with light from below. Reflective light is very important for observing transparent patterns, such as leaves, small insects, etc .. Under the 90 x 90 mm table of the learning microscope, intended for depositing the observed objects, there is a six-color rotating plate with six colored glasses (filters) , make very bright patterns easier, and more accurate to watch. The six-color rotating plate contains lenses with blue, light blue, green, yellow, purple, and colorless.

The power supply of the double illumination of the microscope is arranged via a connection cable with a supply voltage converter. The length of the electrical connection cable with the voltage transformer is 200 cm. Dual-lighting wireless power is also enabled with two AA-size battery packs. In this way, we can use a microscope to work in places where there is no electrical outlet nearby. For example, field work.

With a digital camera with a USB port, the observed patterns can be observed on a computer screen. The software on the CD (CD - CD) allows you to capture a screen image and record videos. An electronic eyepiece (digital camera) can be inserted directly into the microscope tube. The length of the USB connection cable (USB cable) for transferring the image from the electronic eyepiece to the computer is 150 cm. The learning microscope has three legs built-in at the bottom and a durable base (Microscopic foot) for its reliable, quiet and firm placement on the base

A robust suitcase makes it easier to carry, protect against shocks and store the microscope and accessories. In addition to the learning microscope, the case contains 10 object slides, 5 cover glasses, four marked closed plastic containers with microscopy ingredients, an egg hatchery, a safe tool for precise cutting of thin slices of preparations, a protective tarpaulin for the microscope and pincers.

Smooth slides with trimmed edges for added safety and cover windows are laidav padded plastic box with the possibility of safe storage of twelve object (roof) windows. Between the enclosed object and roof glasses, there are observed objects (preparations) already inserted between the object and the roof glass. Included preparations are: housefly leg, onion skin, cross section of cotton stem, pine pollen and cross section of dicotyledon (sunflower).

Among the accessories in the case are also four marked closed plastic containers with screw caps with the contained ingredients and a substance for the permanent manufacture of objects (preparations) for observation with a microscope. The sealed, marked plastic containers contain saltwater crayfish eggs, sea salt intended for the preparation of saline solution (brine) for the development and survival of saltwater crayfish, yeast intended as food for the development and survival of saltwater crayfish, and a rubber conductor (intermediate) for permanent bonding (umbrella) slides on object slides with the observed object (preparation) inserted in the middle. For successful hatching of saltwater crayfish eggs, a four-chamber hatchery with a lid is included, which enables the viewing of saltwater crayfish directly in the hatchery. The hatching of saltwater crab eggs in the hatchery is carried out with the help of the drawn individual stages of development of this interesting living creature.

Safe and precise cutting of thin slices of preparations (objects for observation with a microscope) is enabled by the included double-sided sharp razor in a rotating protective housing with two openings for safe insertion of objects intended for cutting into thin slices. Tweezers were added.

Plastic protective tarpaulin (PE-LD) protects the learning microscope against dust and other dirt. The dimensions of the protective tarpaulin are 33 x 20 x 26 cm (height x width x length).
