Polarisation

Microscopes with polarisation are a critical tool for modulating light and examining materials in a variety of ways. Dino-Lite USB microscopes with polarisation filters are designed to reduce reflections, reveal invisible layers and improve contrast.

When used with a backlight, users can also detect mechanical stresses and identify optically anisotropic materials. Dino-Lite USB microscopes that have a polarising filter are used in a variety of fields. These include forensics, manufacturing, health, mineralogy, research and biology.

USB Microscopes with Polarisation

Traditionally, most polarised light microscopes are equipped with two polarisers to produce the linearly polarised light and create different light polarisation configurations. One polariser is placed in front of the light source to polarise the light. The other polariser is placed between the target and the camera sensor or observation tube, blocking or transmitting the light reflected or transmitted from the target.

Microscopes with polarised light can produce different polarisation configurations depending on the relative orientation between the polarisers: Parallel polarisation is the configuration for polarisers aligned parallel to each other, and cross polarisation is the configuration for polarisers aligned perpendicular to each other. Depending on the polarisation configuration and the interaction of the incident light with the target, the light is transmitted or blocked.

Design of the Dino-Lite polarisation

The Dino-Lite USB microscopes with polarisation are equipped with an adjustable polariser and a fixed polariser, as shown in the picture below. The adjustable polariser, located in front of the Dino-Lite's LEDs, polarises the microscope's light source. The fixed polariser, located behind the lens of the Dino-Lite, polarises the light between the target and the camera sensor.

The degree of alignment between the polarisers can be controlled by turning the wheel of the adjustable polariser. The dial has an arrow pointing to the current degree of alignment between the polarisers, where "0" is parallel polarisation and "90" is cross polarisation.

Applications of Dino-Lite microscopes with polarisation

Reducing reflection and inspection of glass and other materials

Light reflection hinders inspections in a wide range of applications. Dino-Lite polarising digital microscopes can reduce glare to provide clearer images.

Any user inspecting materials with smooth surfaces or surfaces covered with grease, oil or liquids will benefit from using Dino-Lite's polarising digital microscopes.

Identify and characterise optically anisotropic materials

By combining a BL-ZW1 backlight and a Dino-Lite polarising digital microscope, observers can identify and characterise optically anisotropic materials.

Crystals, many plastics and biological tissue are some examples of optically anisotropic materials that can be studied with Dino-Lite polarising digital microscopes.

Observation of upper and lower skin layers

The upper skin layer reflects light while maintaining its polarisation, while the lower layers scatter and randomise the polarisation.

Consequently, parallel polarisation emphasises the upper skin layers, while cross polarisation emphasises the lower skin layers.

Dino-Lite Microscope AM7915MZT

The microscope is a useful instrument for precise measurements that can be made quickly and easily via the software. With the measurement function you can determine lines, angles, radii and circles. The measurement results and the corresponding image can be exported to Excel at the click of a mouse to create a complete measurement protocol. A direct transfer of the magnification into the DinoCapture software is ensured by the automatic magnification readout . This allows measurements to be taken both in the LIVE image and later on stored images. An precise calibration of the microscope is essential to perform precise measurements. Thanks to the ease of use of the supplied calibration standard and the user-friendly software, calibration can be performed quickly and easily. The software guides you step by step through the calibration process to achieve the best results. In the aerospace industry, extended depth of field through the EDOF function can help to obtain more precise images of aircraft parts and spacecrafts. This can help improve the safety and efficiency of aircrafts and spacecrafts. Good illumination is important in microscopy to achieve good results. Dino-Lite microscopes come with their own illumination - 8 white LEDs built into a ring light. Using the FLC (Flexible Light Control), the LEDs can be dimmed from 100% to 6.25% or switched off completely. In addition, the LEDs can be switched on and off in pairs. This way - if needed - the light can shine on the workpiece from different directions and lead to even better results. The Polarisation filter is also used for suitable illumination of the specimens. Due to the infinitely variable adjustment, light reflections occurring on the material can be reduced as far as possible.. Thanks to the front cap system of the microscope, you can work without a front cap to obtain a clear and undistorted view of the object to be examined. This makes the examination and analysis of samples much easier. Front caps are supplied with the microscope (may vary depending on the microscope) and can be easily added to ensure optimal adaptation to the specific application. By using the diffusers, a special light diffusion can be achieved which helps to reduce light reflections. If you need assistance in choosing the right Dino-Lite microscope, we are at your disposal.

Dino-Lite microscopes are a series of different microscopes that can be connected to a Windows computer or Mac PC via USB. In addition, there are the series that have their own wireless connection and thus send the signal directly to a smartphone. The included software enables quick measurement of surfaces and components. The measurement results can be transferred directly to Excel. In addition, the images can be exported in almost any image format for further processing. With up to 5 megapixel resolution, even the small details can be displayed clearly and distinctly. The built-in chipset enables exceptionally good colour and image reproduction. Depending on the handheld microscope, you can achieve up to 900x magnification. As a rule, normal use is between 50x and 230x magnification. Various features then round off the overall package of the Dino-Lite microscopes.
