Domestic Plan Achromatic Objective IOPCSO146460X-VIS
JCOPTIX domestic plan achromatic objectives use infinity-corrected designs correcting curvature/distortion and aberrations at two visible wavelengths for good flatness and low spherical/chromatic aberration. Standard RMS threads adapt to SM1 internally threaded holders using JCOPTIX MTA-SM1F. Housings bear function, magnification, NA, a coverslip-free-imaging number, and effective tube-lens focal length. Domestic infinity plan achromats: infinity-corrected plan design; 180 mm tube lenses; good flatness; 45 mm parfocal distance; standard upright biological microscopes. Dry magnifications: 2X, 4X, 10X, 20X, 40X, 60X; oil: 100X. Suitable for basic/advanced microscopy. High NA/magnification suit laser focusing/collimation. Diffraction-limited visible performance supports imaging and focusing monochromatic/broadband light into waveguides/fibers. All suit standard upright biological microscopes. Domestic plan achromatic positive-phase-contrast objectives: infinity-corrected plan design, good flatness, 180 mm tube lenses, 45 mm parfocal distance, standard upright phase-contrast microscopy. Magnifications: 10X, 20X, 40X, 100X. They provide good flatness and effective contrast for transparent colorless specimens. Domestic ultralong-working-distance plan achromats: 220 mm tube lenses. Long clearance reduces sample-damage risk. Transmission >90% over 400-700 nm. Parfocal: 45 mm. Standard inverted biological microscopes. Magnifications: 4X, 10X, 20X, 40X, 60X. Long working distances reduce damage risk; ideal for brightfield on standard inverted microscopes. Domestic ultralong-working-distance plan achromatic positive-phase-contrast objectives: 220 mm tube lenses; reduced sample-damage risk; >90% transmission over 400-700 nm; 45 mm parfocal distance; standard inverted phase-contrast microscopy. Magnifications: 4X, 10X, 20X, 40X. They provide flat phase-contrast images with long clearance. High signal-to-noise ratio, resolution, and contrast support transparent colorless specimens.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
