An achromatic feature: this biconvex lens adopts an achromatic design, which can reduce the dispersion of different wavelengths of light in the lens, resulting in a clearer image.
Combined structure: The two lenses are bonded together to improve optical stability and image quality, as well as to enhance the mechanical strength of the lenses.
High-precision focusing ability: with a long focal length of 300mm, it is suitable for telescope DIY projects, enabling clear observation of objects at a distance.
High-grade optical glass material: Optical glass has excellent optical properties, including high light transmission and good scratch resistance.
