Ziele
Objektive sind das Ende eines jeden Mikroskops, aber sie haben auch in vielen anderen Anwendungen Verwendung gefunden, z. B. in Hochleistungslasern sowie UV- und IR-Anwendungen. OptoSigma-Objektive sind mit 5- bis 100-facher Vergrößerung erhältlich und können auch mit einer Deckglaskompensation ausgestattet werden, die zur Korrektur der sphärischen Aberration modifiziert werden kann, um Proben mit verschiedenen Brechungsindizes zu untersuchen. Wir bieten auch Objektive mit langem Arbeitsabstand an, und wenn eine Korrektur der chromatischen Aberration erforderlich ist, bietet OptoSigma auch reflektierende Objektive an, die für den Breitbandeinsatz optimiert sind. Unsere Standardlinsen sind unendlich korrigiert. Vollständig kundenspezifische Objektive sind möglich, fragen Sie einfach nach.

|---|---|---|---|---|---|---|
UV Objectives |
These UV objective lens are infinity corrected and can be used for laser machining with pulsed 3rd and 4th harmonic YAG Lasers. Chromatic aberration is suppressed in both the visible and UV laser wavelength, achieving a high transmittance. Available with glass thickness compensation. |

3.5-30.5mm |
|
Visible Objectives |
Visible objective lenses are available in standard and long working distance (LWD) versions. Chromatic aberration and infinity correction is available with LWD types. The objective will allow user to focus a visible laser or perform microscopic observation of objects from a distance. |

|
IR Objectives |
IR objective lens have high numerical apertures and are infinity corrected. They are used for laser machining with pulsed fundamental-harmonic YAG Lasers. Chromatic aberration is suppressed in the visible laser wavelength, achieving a high transmittance. Available with glass thickness compensation. |

Multi-Wavelength YAG Laser Objectives |
These objective lens can be used for machining with YAG lasers. A single objective can be used for all three harmonic wavelengths: 2nd HG, 3rd HG, and 4th HG. Multi-wavelength objectives are infinity corrected and have long working distances. |
