- Designed for trinocular stereo microscopes, this auxiliary lens offers four magnification options: 5x, 0.7x, 1.0x, and 2.0x to cover a range of observation needs. - The innovative zero-magnification (0x) lens preserves the working distance and protects the main optics from wear. - The 0x option enables clear viewing of objects from as close as 30 mm, allowing you to resolve fine details at near distances. - Mount diameter is 1 7/8 in (48 mm), allowing seamless integration with most existing stereomicroscope setups. - Practical use scenarios: - Biology and botany: scan specimens at 5x for overview, switch to 2.0x or 0.7x for detailed features, with the 0x lens maintaining distance and protecting optics. - Electronics and materials inspection: inspect solder joints or microstructures using 0.7x or 2.0x as needed. - Education and demonstrations: quick magnification changes to show both context and fine details to students.
