Enhanced magnification options: Choose from 0.5X, 0.7X, 1.0X, 2.0X for flexible observation, with each lens delivering precise optical performance for detailed specimen examination. Wide compatibility: Designed for trinocular and binocular stereo zoom microscopes; standard 48mm (17/8') mounting diameter fits most microscope models without adapters. Optimized working distances: The 0.5X and 0.7X lenses extend working distance to 120mm and 165mm respectively while reducing magnification, ideal for handling larger specimens or performing delicate procedures under the microscope. Precision optics and durable construction: Precision glass optics with longlasting ABS construction deliver clear, distortion images and maintain optical integrity through extended use in laboratory or educational settings. Use scenarios: Educational labs: Observe fine cellular features or leaf venation at higher magnifications (1.0X or 2.0X) while keeping specimens comfortable under extended views. Large specimens handling: Use 0.5X or 0.7X with extended working distances to examine leaves, insects, or larger samples without crowding the eyepieces. Delicate procedures: Conduct micromanipulation or precise observation during procedures thanks to added working distance and consistent image quality.
