Product Details

  • Precision N-BK7 Substrate
  • Optimized for Use in Collimated Light with Small Fields of View
  • Transmitted Wave Front Accurate to λ/16

Many optical systems experience some level of spherical aberrations which result in a loss of image quality and overall system performance. Our line of TECHSPEC® Spherical Aberration Compensation Plates are designed to compensate and correct known amounts of spherical aberration at the specified wavelengths. The aberration plates should be used in collimated space and placed near a pupil. They are excellent for correcting spherical aberrations in systems that have small fields of view.

Spherical Aberration Compensation Plates can be combined to induce the desired amount of compensatory spherical aberration. Negative sign plates create over corrected spherical aberration. Positive plates create under corrected spherical aberration.

Note: The arrow on the spherical aberration compensation plates points in the direction of light travel.
