Fiber Inspection Microscope – 200× & 400×

Ships direct from the manufacturer. Please allow up to 10 business days, though it often ships sooner.

Contaminated connectors are the leading cause of fiber link failures, and the dust, oil, and scratches behind them are too small to see with the naked eye, so a look under a microscope is the fastest way to know whether an end face needs cleaning before it's plugged in or tested. The Jonard Tools FIM-200 and FIM-400 are handheld fiber inspection microscopes for exactly that check, at 200× or 400× magnification through an achromatic lens with a focus wheel. Fit the 2.5 mm adapter for SC, ST, and FC connectors or the 1.25 mm adapter for LC, insert the connector, switch on the coaxial LED light, and turn the focus wheel until the end face is sharp. Built-in laser filters protect your eye, but the microscope is not meant for live fibers, so make sure the fiber is dark before you look. Both come with a rubber cover, a cushioned nylon case, and three AAA batteries, and are backed by Jonard's lifetime warranty. Choose the magnification from the menu above: 200× (FIM-200) is the general-purpose inspection view, and 400× (FIM-400) shows finer scratches and smaller particles on the end face.

Features

• 200× or 400× magnification. An achromatic lens and a focus wheel give a sharp view of the connector end face and the fiber; pick the FIM-200 for routine checks or the FIM-400 for a closer look.
• Adapters for most connectors. Includes a 2.5 mm adapter for SC, ST, and FC and a 1.25 mm adapter for LC; the 2.5 mm adapter works with standard and outdoor simplex connectors.
• Coaxial LED illumination. Lights the end face along the line of sight for a clear view of the ferrule and the fiber, and is easy on the batteries.
• Laser filters for eye safety. Integrated filters protect your eye, but the microscope is not intended for use with illuminated fibers.
• Field ready. Rubber cover for protection, a cushioned nylon case, three AAA batteries, CE certification, and a lifetime warranty.

Where It Fits

It suits fiber installers and splicers who inspect every connector before it goes into a port, data center and enterprise teams troubleshooting a link that passes on paper and fails in practice, FTTH technicians checking SC/APC drops and terminal ports where a dirty end face reads as low power, test and certification work where the standard requires an inspected connector before the loss measurement, anyone who cleans connectors and wants to see whether the clean worked, and a fiber kit where the microscope pairs with the FCC-125 and FCC-250 cleaners, as it does in Jonard's TK-189 cleaning and inspection kit.

Good to Know

Never look at a live fiber through this microscope. The laser filters are a backstop, not a license; confirm the fiber is dark by unplugging the far end or checking it with a power meter or an identifier before you inspect, and treat an unknown fiber as live until proven otherwise. The routine is inspect, clean, inspect: look first, clean with a push cleaner if there's anything on the end face, and look again, since a cleaner can only remove what it reaches and a second look catches what the first clean smeared. Fit the adapter that matches the ferrule, 2.5 mm for SC, ST, and FC, 1.25 mm for LC, and seat the connector fully before focusing; a connector that's loose in the adapter won't hold focus. At 200× the whole end face is in view, which is the right magnification for spotting dust and oil fast; at 400× the view is tighter and shows fine scratches and small particles that 200× can miss, which matters for single-mode and APC connectors where the core is small and the standard is strict. For inspecting the far side of a bulkhead adapter or a port, a probe-style scope is the tool; this is a handheld microscope for the connector in your hand. Change the batteries when the LED dims rather than when it dies, since a dim view hides the contamination you're looking for. Keep the rubber cover on and the microscope in its case between uses; a scratched lens looks like a scratched fiber.
