Typesof microscope 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.

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.

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.
