Delta Optical Genetic Pro Bino Microscope

Biological microscope with a binocular head designed for observation in bright field. It is suitable for education, university labs, or laboratories. It can also be used by people developing an interest in microscopy who need equipment that allows observation of biological specimens across a wide magnification range.

A stable design in a upright configuration, a wide eyepiece field of view, and a mechanical stage for 2 slides create a set adapted for regular work. The binocular head enables observation with both eyes. The tubes are inclined at an angle of 30 deg., which eliminates the need to lean the head excessively over the eyepiece.

The binocular head is equipped with 2 WF 10x eyepieces with a 18 mm field of view. The wide-field design makes it easier to observe a larger area of the specimen, which is important when locating structures of interest and working at lower magnifications.

The interpupillary distance can be adjusted within the range of 48-75 mm, allowing the eyepiece position to be matched to the individual eye spacing. The left tube features diopter adjustment within the range of +/- 5D, useful when there is a difference in visual sharpness between the eyes.

The microscope is equipped with a 4-position objective turret with achromatic objectives 4x, 10x, 40x and 100x OIL. Combined with 10x eyepieces, it provides total magnifications:

• 40x - for locating and viewing larger areas of the specimen
• 100x - for observing selected elements of the sample
• 400x - for working with fine biological structures
• 1000x - with the 100x OIL immersion objective

Achromatic objectives reduce the basic color defects of the image, supporting the clarity of details visible in transmitted light. The 4-position objective turret enables quick switching between objectives and gradual magnification increase without removing the specimen from the stage.

The model uses bright-field observation technique and LED transmitted illumination. The light source is located under the stage and directs the beam through the specimen toward the optical system. The technique is used for observing properly prepared, thin biological specimens, both fresh and permanent.

The LED diode provides stable light and features a long service life. It does not require regular replacement like traditional bulb sources, and the emitted light does not cause significant heating of the sample. The microscope is powered by an external DC 5 V / 0,5 A source.

An Abbe N.A. 1,25 condenser is placed under the stage, and its task is to focus light on the specimen. It works together with an iris diaphragm, which allows adjustment of the amount of light passing through the examined sample. Proper adjustment of the condenser and diaphragm makes it possible to match brightness and contrast to the type of specimen and the objective currently in use.

The design based on 160 mm optical correction corresponds to the standard used in biological microscopes of this type. It allows stable observation in the basic bright-field technique.

On both sides of the microscope there are coaxial coarse and fine focus adjustment knobs. The coarse adjustment knob is used for quick, initial focusing, mainly at lower magnifications. Fine adjustment allows precise refinement of the image, especially when working with 40x and 100x OIL objectives.

The minimum increment of fine movement is 4 µm, which allows small, controlled changes of the stage position relative to the objective. The double-sided arrangement of the knobs allows convenient right- or left-hand operation.

The mechanical stage measuring 142 x 132 mm allows simultaneous placement of 2 slides. The holder keeps the slides in a fixed position, and the travel mechanism allows precise movement of the observed material along the X and Y axes.

The travel range of the mechanism is 75 x 40 mm, which makes it easier to inspect a larger part of the specimen. The vernier scale helps determine the position of the examined area and find it again during subsequent observations or result documentation.
