Tight the light source probe with the receiving probe on the holder, the light transmittance is displayed as 100.00% in the interface. Lift up the receiving probe and put the test sample into the holder, and then tightly attach the receiving probe to the light source probe again. The current “T” value is the transmittance value of the test sample, and the current OD value is the optical density value of the test sample.

A stereo microscope, also known as a stereoscopic or dissecting microscope, provides three-dimensional viewing of larger, opaque specimens through dual optical paths with objective lenses. It offers lower magnification (typically 5x to 40x) than compound microscopes but enhances depth perception. Ideal for tasks in biology, geology, and manufacturing, it allows comfortable, extended viewing with ergonomic adjustments.

In the case that it's impossible for the test sample (like large lamp chimney) to be put into the holder and it's necessary to remove the light source probe and the receiving probe from the holder, the Probe-in-hands method is used to measure the sample, with the testing process as shown in the followings:

OD is an abbreviation for optical density, which means the density of light absorbed by the detected material. It is a proper noun in the detection method, and the general understanding of the more difficult specific detection involves a lot of physics and other knowledge you only need to know is negative light through the detected material, the difference in energy before and after is the energy absorbed by the detected material, a specific wavelength, and the same detected material.

Capable of high magnification, which is achieved through the combination of the objective lens (typically 4x, 10x, 40x, and 100x) and the eyepiece (usually 10x).

Shooting with a shallow depth of field is having a plane that's in focus, and everything else is out of focus, explains experienced photographer Jeff Carlson.

Provides high magnification (up to 1000x or more) and high resolution for viewing fine details of cells, tissues, and microorganisms.

In chemistry, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material, and spectral absorbance or spectral decadic absorbance is the common logarithm of the ratio of incident to transmitted spectral radiant power through a material. Absorbance is dimensionless, and in particular is not a length, though it is a monotonically increasing function of path length, and approaches zero as the path length approaches zero. The use of the term "optical density" for absorbance is discouraged.

Compound Magnification is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece.

Magnification is the process of enlarging the appearance of an object, making it look bigger than its actual size. In optics, it is the ratio of the size of the image produced by a lens or microscope to the actual size of the object being viewed.

Absorbance is the logarithm of the ratio of the incident light intensity before the light passes through the solution or a substance and the transmitted light intensity after the light passes through the solution or the substance, and the factors affecting it are solvent, concentration, temperature, etc. The absorbance coefficient is related to the wavelength of the incident light and the substance through which the light passes.

Navigate effortlessly through magnification levels and focus adjustments. Our microscopes feature intuitive controls, allowing you to concentrate on your research without the hassle of complicated settings.

Magnification works by bending light through lenses or using digital technology to enlarge the appearance of an object, allowing for detailed observation and analysis.

Compound microscopes are suited for detailed examination of microscopic structures, while stereo microscopes are more appropriate for observing larger objects in three dimensions and for tasks that involve manipulation and dissection.

A darkfield microscope is a type of optical microscope that provides high contrast images of unstained specimens by using scattered light. The specimen appears bright against a dark background

A microscope is a scientific instrument used to magnify and observe objects that are too small to be seen with the naked eye. It works by focusing light or electrons to create an enlarged image of the specimen.

In physics, a closely related quantity called "optical depth" is used instead of absorbance: the natural logarithm of the ratio of incident to transmitted radiant power through a material. The optical depth equals the absorbance times ln(10).The calculation formula of optical density is:  OD= log10 (1 / Transmittance) = log10 (Incident Light / Transmitted Light)

Objective lens microscopefunction

Optical density means that the density of light absorbed by the test substance, OD = 1og (1/trans), where trans is the light transmission value of the test substance.

The terms monocular, binocular, and trinocular refer to the different types of microscope heads, each offering a distinct way of viewing the specimen.

A specimen is a sample or example used for scientific study. It can be anything from biological tissues to materials, examined under a microscope or other instruments for analysis.

As for light transmittance of various milky, fogged, abrasive and matte materials, such as milky and abrasive glasses, ceiling lamps, diffuser, and zirconium oxide, etc. The two testing methods are adopted subject to size of the test sample.

A trinocular microscope head combines the benefits of binocular viewing with the capability to capture digital images or videos of specimens. It is particularly suited for advanced research, educational purposes, and industrial applications where precise imaging and documentation are essential.

Microscope objectives are vital lenses that determine the magnification, resolution, and quality of the images produced by a microscope. They come in various types and magnifications, each suited for different applications and levels of detail, making them indispensable in scientific research, medical diagnostics, and educational settings.

Align and keep those two probes in tight before powering the meter on. After “Warm-up”, the meter enters into measurement interface, with T displayed as 100.00%.

A Compound Microscope is a type of optical microscope that uses multiple lenses to magnify small objects. It consists of two sets of lenses: the objective lens, which is closer to the specimen and provides the initial magnification, and the eyepiece lens, which further magnifies the image for the viewer's eye. Light passes through the specimen and is magnified by the objective lens, then further magnified by the eyepiece lens, resulting in a highly magnified image visible to the observer. Compound microscopes are commonly used in biology, medicine, and other scientific fields for viewing cells, tissues, and other small structures.
