Flat-field semirefractive infrared objective
● Specialized NIR objective lens, corrects aberration from visible to NIR wavelengths. Suitable for conventional brightfield and specialized IR observation.
● High-magnification, large numerical aperture objective lens has correction ring to correct cover sheet thickness difference aberration. Coated with near-infrared transmittance enhancement film. Center wavelength covers visible to near-infrared.
● Flat image surface, small spot distortion. Obtains high-definition near-infrared imaging without extensive post-processing.
