Reasonable Achromatic Lens 30mm Diameter 300.4mm Focal Length

S-DLB-30-300PM

An economic general use achromatic lens suitable for an optical system, which does not require high surface quality imaging such as a microscope lens or 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.

Attention
  • Achromatic lens is used when focusing an image at infinity or when making the point light source to collimated light. It does not provide sufficient optical performance when used in such as short-range imaging.
  • There is a direction of the incident parallel light with achromatic lens. The radius of curvature is allowed to be incident parallel light from the side of (the surface indicated by arrows) small curvature surface. If the parallel light incidents from the opposite side, then spherical aberration and chromatic aberration occur and the focused spot size will be large.
