Product overview This interchangeable monocular drawtube accessory is designed for video microscope systems. It is made from durable plastic and delivers stable long term performance when used with compatible equipment. Available magnification factors let you adjust image scale to match inspection and imaging needs. Key benefits Flexible magnification options: Choose from 0.5X, 0.7X, 0.75X, 1.5X, or 2.0X to reduce or increase the effective magnification of your video microscope system. Works with systems that produce up to 500X and under. Simple mechanical compatibility: Standard 17/8 inch (48 mm) mounting thread fits many common monocular video microscope setups, making integration straightforward. Lightweight and durable: Plastic construction keeps the unit light for easy handling while providing stable performance for repeated use. Improves imaging workflow: Changing the drawtube magnification lets you quickly adapt field of view and working distance without modifying the main optics. Specifications Color: 0.7X Magnification power options: 0.5X, 0.7X, 0.75X, 1.5X, 2.0X Magnification ratio: 500X and under Theory: Video microscope Drawtube: Monocular Mounting thread: 17/8 inch (48 mm) Material: Plastic Practical applications Electronics inspection: Adjust magnification to inspect solder joints, component placement, and trace defects on printed circuit boards. Quality control and assembly: Quickly switch magnification to verify small mechanical parts, fasteners, and assembled subcomponents on a production line. Education and training: Use with classroom video microscopes to demonstrate differences in field of view and detail at multiple magnification settings. What this product solves This drawtube accessory lets you tailor the effective magnification and field of view of a monocular video microscope without replacing the primary optics. It simplifies setup changes, reduces the need for multiple objective lenses, and keeps inspection and imaging tasks efficient and repeatable.
