Lens for a clear visionary observation. The 10x/0.25 objective resolution limit is 1.1 μm. Chromatic aberration is blue and red, spherical aberration for green, and the curvature of the field of view is 90%of the diameter of the field of vision.

The lens is designed for an infinitely adjusted tube length. The parcocal distance is 45 mm. When using a 10/22 mm lens, the field of vision is 2.2 mm diameter. The lens was designed for use with patterns with 0.17 mm tops.

The lower limit of the microscope is 10x and 125x when used objective. A lower degree of magnification does not allow the details of the object to be distinguished in the image taken by the lens. The upper limit of the useful magnification is 250x when using 10x lens. The higher degree of magnification is usually considered "useless" because it does not provide new details of the sample. When a 10x/0.25 lens is installed, you can use the 12.5x to 25x eye lens for the useful magnification value of the microscope, and use the 10x lens to scan the sample and search in the sample area.

For flat-acromatic lenses, the focus is the same as the center of the image, so the distortion is negligible. This strength is used for digital imaging and pairing with 22 mm high-angle lenses.
