Objectives

Objective lenses for various applications are available in this section, starting from a simple imaging lense to a complexe microscopy objectvie lens. A large range of objective lenses designed in different wavelenght UV, Visible and NIR or IR for your detectors and sensors. Scan objective lense, large image sensor lenses are also available. Long working distance and high NA lenseS.

  • Glass thickness (0.7 mm and 1.1 mm) Compensation Objectives

    Description

    These objectives are designed with compensation for cover glass-thickness aberrations, making it possible to realize ideal beam spot size and quality while processing thorough a cover glass. These objective lenses can be used for laser repair processing for LCD or OLED modules.

  • YAG 3-Wavelengths Objectives (266 nm, 355 nm and 532 nm)

    Description

    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.

  • YAG 2-Wavelengths Objectives (355 nm and 532 nm)

    Description

    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.

  • Near Ultra-Violet Objectives (350 nm - 800 nm)

    Description

    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.

  • Infrared Objectives (400 nm - 1400 nm)

    Description

    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.

  • Visible Objectives (400 nm - 750 nm)

    Description

    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.

  • Reflective objectives

    Description

    These reflective microscope objective lenses eliminate chromatic aberration over a wide bandwidth from the UV to the MWIR. They are typically used in microscope-spectrometry and failure-analysis applications in the semiconductor industry.
