NA 1.25 Condenser for Microscopes Key benefits Precise light control: Adjustable aperture lets you control light entry and convergence to achieve contrast and clarity for different specimens and objectives. Brighter, sharper images: The condenser concentrates illumination onto the sample and allows height adjustment so the focus of light matches the observed area for maximum brightness. Durable and easy to use: Metal construction and a simple tool installation and removal process make this condenser long lasting and convenient to maintain. Features Numerical aperture NA 1.25 for resolution illumination. diameter 37 mm to fit common microscope condensers. Adjustable aperture to fine tune light input and gather light for the viewing effect. Optical assembly of 2 to 3 lens elements. The front lens faces the objective and includes a flat surface suitable for use with objectives of different NA values. Height adjustment to align the illumination plane with the sample for focus and brightness. Metal material provides strength and resistance to damage during regular use. Compatibility and use Designed to work with standard microscope objectives, for example 100X NA 1.25, 40X NA 0.5, and 10X NA 0.25. Suitable for inspecting small objects such as coins, jewelry, cosmetics packaging, watch components, and other small parts that require detailed visual inspection. Typical applications Coin and numismatic inspection: concentrate light to reveal surface details, wear, and minting marks. Jewelry and gemstone appraisal: enhance clarity and contrast to inspect settings, inclusions, and surface quality. Watch and small parts : provide focused, NA illumination for assembly, cleaning, and detailed inspection of tiny components.
