Achromatic Doublet Lenses

  • Introduction

Achromatic Doublet Lenses


At Hyperion Optics, with decades fabrication experiences, we have been providing our customer a vast number of achromatic lenses for their applications in different precision grades, please check our test plate radius available online for download to save your cost on custom achromatic doublet lens design. Particularly for cost-sensitive design, our series production capability always ensures a satisfying pricing solution.


As optical designers widely use doublets which contribute latitude to eliminate chromatic and spherical aberrations more thoroughly. We also provide excellent suggestions for glass material selection in individual design as we distinguish the importance of refractive index precision in material selection stage despite the design data in software.


Universally, with particular flint glass designers might choose, certain glass’ deliquescence attribute lead to cosmetic failure after polishing, or even affect the transmission after coating. Let us help to avoid such problem in your design to live process.
