Modern optical microscopes are an indispensable tool for research that involves the visual study of biological and non-biological samples. The objective of modern optical microscopes is to provide a high resolution image of an object to the researcher. The PLJT20 application field and working principles are essential for optical microscope users to understand.

PLJT20 Application Field

The PLJT20 application field covers virtually all aspects of optical microscopy including medical diagnostics, microscopy, advanced imaging, and spectroscopy. In the medical diagnostics field, PLJT20 lenses can be used to examine cells and other medical specimens to help diagnose and monitor diseases. In the microscopy field, the lenses are used in various types of microscopes such as stereo, confocal, and scanning electron microscopes. In the advanced imaging field, the lenses are used in cameras, telescopes, and advanced imaging systems. And in the spectroscopy field, the lenses are used in customized spectroscopy systems.

PLJT20 Working Principles

The PLJT20 is a multifunctional objective lens that uses the principles of total internal reflection (TIR), which ensures high numerical aperture values and high resolution. When a sample is placed under the objective lens, the light is refracted on entering the lens and is then focused on the sample surface. As the light is reflected from the sample surface, it is again refracted when leaving the lens and then focused on the eyepiece. The total internal reflection between the sample and the lens surface allows for maximum light transmission and image resolution with minimal chromatic aberration.

When using the PLJT20 lens, it is important to properly set the numerical aperture according to the application. The numerical aperture is the degree of light that is captured in each image. By setting the numerical aperture, the light transmission and resolution of the lens can be optimized. Additionally, the PLJT20 lens is equipped with adjustable iris and polarization filters, which allow the user to make fine adjustments to the amount of light passing through the lens.

Summary

The PLJT20 lens is a versatile tool for microscopy and imaging applications. It makes use of the principles of total internal reflection to ensure high resolution images with minimal chromatic aberration. Additionally, the numerical aperture can be adjusted, along with polarized and iris filters, to optimize light transmission and resolution. This makes the PLJT20 an ideal choice for medical diagnostics, microscopy, advanced imaging, and spectroscopy applications.
