Concave and convex lens
Whatsapp Order
Concave and Convex Lenses are essential optical components used to manipulate light by refraction. A convex lens is thicker at the center and converges light rays to a focal point, while a concave lens is thinner at the center and diverges light rays. These lenses are fundamental in various scientific experiments, optical instruments, and educational demonstrations to study image formation, focal length, magnification, and light behavior. Manufactured with high-quality optical glass or plastic, they offer clarity and precision necessary for laboratory and industrial applications.

Concave mirrors
Product Description
Concave Mirrors are curved reflective surfaces that converge light rays to a focal point. They are widely used in scientific experiments and optical devices to focus light and form real or virtual images depending on the object's position relative to the focal length. Made from high-quality polished glass or metal with a reflective coating, these mirrors provide precise image formation essential for laboratory and industrial applications in optics and physics.
Lens cleaning tissue
Product Description
Lens Cleaning Tissue is a soft, lint-free paper designed specifically for cleaning optical lenses, microscope eyepieces, camera lenses, and other delicate glass or plastic surfaces. It effectively removes dust, fingerprints, oils, and smudges without scratching or leaving residue. Widely used in laboratories, photography, and electronics, lens cleaning tissue helps maintain clarity and prolong the lifespan of sensitive optical components.
Microscope
 Product Description
A Microscope is an essential laboratory instrument designed to magnify and visualize small objects or specimens that are not visible to the naked eye. It uses a system of lenses—typically an objective lens and an eyepiece lens—to enlarge images of biological samples, materials, or microscopic particles for detailed examination. Microscopes come in various types including compound, stereo, electron, and digital, each suited for specific applications in biology, materials science, medicine, and research. High-quality microscopes offer adjustable magnification, fine focus controls, and illumination systems to enhance clarity and contrast. Widely used in clinical diagnostics, microbiology, pharmaceutical research, and education, microscopes are vital for studying cell structures, microorganisms, tissue samples, and more. They provide precise, reliable visualization crucial for scientific analysis and discovery.
Microscope condenser
 Product Description
A Microscope Condenser is a vital optical component in a microscope designed to focus and concentrate light onto the specimen being observed. It is typically positioned beneath the microscope stage and plays a crucial role in controlling illumination intensity, contrast, and resolution during microscopic examination. The condenser gathers and directs light from the microscope’s illumination source into a cone of light focused on the specimen, enhancing image clarity and detail. Condensers often include adjustable diaphragms (such as iris diaphragms) to regulate the amount of light and improve contrast. Available in various designs including Abbe, achromatic, and aplanatic condensers, they cater to different magnification levels and imaging requirements. Microscope condensers are essential for achieving optimal image quality in biological, medical, and materials science applications.
Microscope eye piece
 Product Description
A Microscope Eye Piece, also known as the ocular lens, is the lens or group of lenses located at the top of a microscope through which the user views the magnified specimen. It typically provides an additional magnification—commonly 5x, 10x, or 15x—working in conjunction with the objective lenses to achieve total magnification. The eyepiece contains optical components designed to enhance image clarity, brightness, and field of view. Modern eyepieces may include features such as reticles for measurement, adjustable diopters for individual eye correction, and wide-field optics for increased viewing comfort. Made from precision optical glass and durable housing, microscope eyepieces are essential for delivering a clear, sharp, and comfortable viewing experience in scientific, medical, educational, and industrial laboratories.
Microscope mirror
Product Description
A Microscope Mirror is an optical accessory used to direct and focus external light onto the specimen being examined under a microscope. Traditionally mounted beneath the microscope stage, the mirror reflects ambient or artificial light upward through the condenser and specimen to illuminate the sample. Microscope mirrors typically have one flat and one concave reflective surface, allowing users to adjust the intensity and focus of the light beam. Made from highly polished glass or metal with reflective coatings, these mirrors are essential in microscopes lacking built-in illumination systems or as backup lighting aids. They enhance visibility, contrast, and detail, making them valuable in educational, medical, and research laboratory settings.
