Achromatisches Dublett 10mm Durchmesser 100.5mm Brennweite

DLB-10-100PM

Achromatische Dubletts sind verkittete Achromate aus zwei verschiedenen Linsen (Low Dispersion Positiv aus Kronglas und High Dispersion Negativ aus Flintglas). Der Unterschied in Dispersion und Form beider Linsen wurde entwickelt, um die chromatischen Aberrationen in Blau (486,1 nm), Grün (546,1 nm) und Rot (656,3 nm) zu minimieren. Daher sind diese Linsen in der Lage, das gesamte sichtbare Wellenlängenspektrum zu unterstützen.
◦The spherical aberration of achromatic doublets is better than singlets and minimized at infinite conjugate ratios.
◦Achromatic Doublets are coated on both surfaces with a broadband multi-layer anti-reflection coating for the visible wavelength (400 − 700nm).
◦Set the positive part to the side of the incident parallel beam and put the negative part to the side of the focal point to minimize spherical aberration.
◦The difference in focal length of a lens at each wave length is Chromatic aberration and is due to “dispersion of the glass”, the change in refractive index of glass according to wavelength. This can be corrected by combining glasses with low and high dispersions. Spherical aberration is when a ray enters a lens farther from its optical axis and has a shorter focus than a paraxial focus.
