Our reflective polarizing microscope is a specialized optical instrument designed for examining reflective and anisotropic materials under polarized light. Unlike traditional transmitted light microscopes, it utilizes reflected light to observe opaque specimens like metals, minerals, and other reflective surfaces. These microscopes feature specialized objectives, polarizers, and compensators to control and analyze the polarization of light. Reflective polarizing microscopes are commonly used in fields like geology, materials science, and metallurgy to study crystalline structures, stress patterns, and other optical properties in opaque samples. They play a crucial role in analyzing material composition and quality, making them valuable tools for research, quality control, and failure analysis in various industrial and scientific applications.

We provide digital microscope, a modern optical instrument equipped with a digital camera and imaging technology to capture and display magnified images or videos of specimens on a computer or digital device screen. Unlike traditional microscopes, digital microscopes do not require eyepieces; instead, they offer live, real-time digital visualization, making it easier to share and document observations. These microscopes are versatile tools widely used in various fields, including research, education, and quality control, for their ability to capture high-resolution images, measure objects, and record videos for further analysis.

We provide an inverted biological microscope, a specialized optical instrument designed for studying biological specimens that cannot be easily examined on a conventional upright microscope. Inverted microscopes have their light source and objective lenses positioned below the specimen, allowing for the examination of cells, tissues, and other biological samples cultured in containers like Petri dishes or multi-well plates. These microscopes are commonly used in cell biology, microbiology, and tissue culture applications, providing a clear view of live cells and tissues in their natural environment.
