Achromatic Lenses, Optical Crown and Flint Glass

Esco PN:
  • $ 7590


Achromatic lenses provide diffraction-limited performance over nearly their entire clear aperture. Esco's lens design is computer optimized to insure that chromatic and spherical aberrations are simultaneously minimized. Lenses are suitable for use in most high resolution imaging systems and any application where spherical and chromatic aberrations must be reduced.

All standard achromatic lenses that Esco manufactures are supplied with MgF2 single layer anti-reflective coatings on both outside surfaces. Their performance is superior to that of all single element lenses.

Esco also manufactures custom optical elements, including:

  • Negative achromats
  • Lenses designed for finite conjugate systems
  • Lenses whose designs have been optimized for specific wavelengths, such as the ultraviolet or near infrared
