Product overview A set of precision RMS microscope objectives designed for reliable performance and straightforward compatibility. Size: 20X. Multiple magnification choices let you match the objective to the sample and task. Key benefits Protects slides and optics: Spring loaded design on 10X, 20X, 40X, and 100X objectives prevents accidental contact between the objective and the slide, reducing the risk of damage to specimens and lenses. Flexible magnification options: Choose from 4X, 10X, 20X, 40X, or 100X to suit low power scanning through power detail work. Wide compatibility: Standard RMS thread ensures fit with microscopes that use the RMS interface, including CX21, CX31, and CX41 series. The connecting thread uses the international standard 4/5 inches by 1/36 inches, with a diameter of approximately 20.3 by 0.705 mm. Durable and stable: Carefully machined components provide consistent optical alignment and long service life under regular laboratory and classroom use. Specifications Size: 20X Magnification options: 4X, 10X, 20X, 40X, 100X Spring loaded: Yes for 10X, 20X, 40X, 100X; No for 4X Connecting thread: International standard interface 4/5 inches by 1/36 inches; diameter approximately 20.3 by 0.705 mm Compatibility: Suitable for microscopes with RMS interface, including CX21 CX31 CX41 series Practical uses Teaching and training: Rapidly change magnifications during lessons or lab sessions for demonstrations and student assays without concern for slide or lens damage. Research and analysis: Observe prepared slides and small samples at multiple magnifications for material science, biology research, and microscopy projects. Industrial inspection and quality control: Inspect fine details on components, printed circuit boards, or surface finishes where reliable focus and objective protection are important. Why choose these objectives These objectives combine standard RMS compatibility, a protective spring loaded design on higher magnifications, and durable construction to deliver consistent performance in educational, research, and industrial settings. The precise international thread dimensions reduce fit issues and make installation straightforward on compatible microscope models.
