1pcs 185 Biological Microscope Achromatic Objective Lens - for Enhanced Clarity and Detail(4X Objective Lens)

The objective lens is made of copper, with silver chrome-plated surface and golden copper exposed at the thread.Non - slip rubber ring, easy to pinch and put, feel comfortable.Low power light aperture is relatively large, imaging will be more bright, the field of vision is large; High power objective lens, magnification ability is significantly enhanced, but the field of vision and brightness are reduced, focusing to find the target requires patience.The bullet is the end of the objective lens with a spring, when observing the object can be telescopic rebound, to protect the specimen and the objective lens, medium and high power objective lens such as 40 times (including) and above multiple belt, oil is 100x the objective lens is used, the lens needs to be immersed in oil observation, oil is the tar, microscope special oil.

• Versatile magnification options: Choose from 4X, 10X, 40X, and 100X to suit various observation needs, from insects to blood cells.
• construction: Made from durable copper with a silver chrome-plated surface, ensuring longevity and reliability in your microscopy work.
• Enhanced imaging clarity: Achromatic devise provides clearer images compared to standard magnifying glasses, making it ideal for detailed scientific observations.
• User-friendly devise: Features a non-slip rubber ring for easy handling and comfortable use during extended observation sessions.
• Spring-loaded objective lens: Protects both the specimen and the lens during use, with the 100X lens requiring immersion in oil for optimal viewing.
