LUMINA achromatic Cemented lenses are assembled by cementing two or more lenses made of different materials, effectively minimizing chromatic aberration and enhancing image quality.
They are widely used in high-end imaging systems, microscopes, optical testing, and scientific research.
Custom combinations and coatings are available for different wavelengths and optical system requirements.
