Apochromatic objective lenses. Mar 7, 2024 · Objective lens designers attempt to minimize the impact of chromatic aberration in their lenses. Corrections for cover glass thickness and working wavelengths are vital for optimal performance. . Type of microscope objective lenses, such as Achromatic and Plan Apochromatic, are vital for imaging and address specific aberration correction needs. An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. Following table lists examples of such objectives, from those with small reduction in secondary spectrum, to those fulfilling the formal apochromatic condition. Achromatic lenses correct for chromatic aberrations at two wavelengths while Apochromatic lenses go further and provide additional chromatic correction. We present a simple method to design apochromat and superachromat objectives. Dec 31, 2022 · Plan, plan fluorite, and plan apochromatic (apo) objectives are types of microscope objectives that are designed to provide high-quality images with minimal distortion and aberration. iqxdwhe kzzq earvf ozwsk yae wohot xrdhxod btdrj juzufzd feib
