Domestic Plan Apochromatic Objective IOPAPSO144420X-VIS

JCOPTIX domestic plan apochromatic objectives have standard RMS threads and infinity-corrected plan apochromatic designs for 180 mm tube lenses. Complex Apo-marked objectives correct red/green/blue chromatic aberration and red/blue spherical aberration. Thorough correction gives larger NA than comparable achromats, high resolution, superior image quality, and higher useful magnification for advanced research microscopy and photomicrography. Each housing bears category, magnification, NA, a coverslip-free-imaging number, and effective tube-lens focal length. Standard RMS objectives mount in SM1 internally threaded holders using JCOPTIX MTA-SM1F adapters. Domestic plan apochromatic objectives: NA up to 1.35. Chromatic correction over 400-700 nm. Uniform flatness over large FOV. Parfocal distance: 45 mm. RMS/20.32 mm × 36 TPI threads. JCOPTIX offers domestic dry objectives at 2X, 4X, 10X, 20X, 40X, and 60X, and oil objectives at 60X and 100X. Correction over 400-700 nm and wide-field flatness suit research-grade upright/inverted biological and laser-confocal microscopes. Domestic plan apochromatic positive-phase-contrast objectives: NA up to 1.35. Chromatic correction over 400-700 nm. Uniform large-FOV flatness. Parfocal: 45 mm. RMS/20.32 mm × 36 TPI. Magnifications: 4X, 10X, 20X, 40X, 60X, 100X. High NA, broad flat fields, and correction from 400 nm to 700 nm support phase-contrast/fluorescence observation of transparent colorless specimens in research-grade upright/inverted biological and laser-confocal microscopes. Domestic plan superapochromatic objectives: high NA and flatness. Complete spherical/chromatic compensation over 400-700 nm. Uniform large-FOV flatness. Parfocal: 45 mm. RMS/20.32 mm × 36 TPI. Magnifications: 10X, 20X, 40X, 60X. High NA and wide flat fields completely compensate visible 400-700 nm chromatic/spherical aberration and sensitively collect fluorescence for sharp images without color bias even in brightfield/DIC. The 60X version is a high-NA silicone-oil objective for deep live-tissue high-resolution imaging. Suitable for demanding upright/inverted biological microscopy, advanced research, and weak fluorescence.
