Achromatische NIR-Linse 25mm Durchmesser 30.0mm Brennweite

DL-25-30PNIR

Durch Verbinden zweier Linsen mit Wellenlängendispersion unterschiedlichen Brechungsindex liefert die resultierende Komponente eine reduzierte sphärische Aberration und chromatische Aberration als bei einer einzelnen sphärischen Linse. Diese achromatischen Linsen können als Fokussierlinse für YAG-Laser (1064 nm) oder LD des nahen Infrarots verwendet werden.

Details

◦The lens design is optimized so that the focal length change is minimized in the near infrared region. The focal length matches at 700nm, 880nm, 1100nm wavelengths and is optimized to minimize aberrations.
◦It is suitable as a collimating lens not only because chromatic aberration but also spherical aberration is collected.

Achtung	Please use achromatic lens when focusing an image at infinity or when making parallel light from the one point of light source. It does not provide sufficient optical performance when used in such as short-range distance imaging. There is a direction to the incident light parallel to the achromatic lens. A surface with a small radius of curvature is allowed to be incident parallel light from a rear surface (the surface the arrow is pointing to). When it is incident parallel light from the opposite side, spherical aberration and chromatic aberration will occur and the focused spot size will increase. When used in the visible region, spherical aberration and chromatic aberration increases. In addition, the transmittance decreases.
