What are the advantages of triplet achromatic lenses made of CaF2 and fused silica?
Wide band transmission: fused silica and CaF2 have good light transmission in the UV to IR bands, suitable for wide spectrum applications.
High chromatic aberration correction ability: the dispersion characteristics of the two materials are very different, which can effectively correct chromatic aberration.
Thermal stability: fused silica and CaF2 have low coefficient of thermal expansion and are suitable for environments with large temperature changes.

What are the applications of triplet achromatic lenses in CaF₂ and fused silica materials?
UV optical systems: such as UV microscopes and UV laser systems.High precision optical instruments: such as astronomical telescopes and high resolution camera lenses.
Triplet achromatic lenses offer excellent performance in chromatic and aberration correction and are suitable for high precision optical systems, but have higher cost, weight and assembly complexity. The choice needs to be weighed against the specific needs of the application.
