非球面アクロマティックレンズ

非球面レンズのメリットは、球面収差を補正する能力です。球面収差は、光の一点集光やコリメートする際に、球面形状の光学素子を使う時に生じます。ここでは非球面レンズの特徴やその性能のメリットから、その製造方法、タイプ別の利点や選定方法を紹介します。

反射防止膜は、透過率を増やす、コントラストを高める、またゴースト像の発生を取り除くことによって、光学素子の効率を大幅に改善させます。

Optical coatings are used to influence the transmission, reflection, or polarization properties of an optical component.

This comparison of the performance of aspheric, achromatic, and spherical PCX lenses in different situations reveals the ideal use cases for each type of lens.

Aspherized Achromatic Lenses, exclusive to Edmund Optics, are doublet lenses consisting of two cemented optical elements that are matched for their color-correction ability and small RMS spot size.

非球面アクロマートは、ガラス製の光学レンズ素子に感光ポリマーを貼り合わせて作られます。このポリマーは、ダブレットレンズの片面側だけに貼り合わされるため、短時間内で容易にレプリカを作ることができます。また、一般的なマルチエレメント部品が持つ柔軟性を使用者に提供します。

When doing basic imaging, how do you determine the magnification an optical lens will provide?

Collimated light occurs when light rays travel parallel to each other.

Although a common misconception, individual optical lenses do not always form an image when the object plane is placed a focal length away from the lens.
