Economical Achromatic Lens

It is a product with lower quality than DLB series with low surface spherical achromatic lens.

Allowed to use optical system, which is not required high surface quality imaging lens such as the microscope lens and telescope lens.

  • Specification except surface quality is almost the same as DLB series. Except when used in high-precision experiment using a laser, this lens is recommended.
  • It is optimized so that focal length gap is small in the visible light range and the aberration is minimized.
  • It is also corrected for astigmatism and comatic aberration of off-axis as well as aberration of axial object point.
