RF4 WD168 Microscope Lens 0.48X Auxiliary Objective

0.48X Microscope Auxiliary Lens for a Longer Working Distance

The RF4 WD168 is a 0.48X microscope auxiliary lens that gives your crowded repair bench what it needs most: space. Screw it onto your stereo microscope objective and your working distance extends to 168mm. That gap decides how comfortably you hold a hot air nozzle, soldering iron and tweezers over a phone board. If your standard objective leaves you cramped during IC change karna or reballing, this lens solves it without a new microscope.

Working Distance vs Magnification

A standard stereo objective sits close to the board. Your hands crowd the optics, and hot air blows straight at the glass. The WD168 pushes the focal point out to 168mm. You trade magnification for that room. The lens reduces your microscope’s magnification to 0.48X of its set value, so the field of view widens and the board fills less of the frame.

A wider view helps when you scan a full motherboard for a hardware fault before you zoom in on a single IC. Low magnification suits inspection, flux cleanup and spotting lifted pads. Refocus your microscope after you mount the lens, because the focus point moves. When you need high magnification for fine-pitch pads, unscrew the lens and return to your standard objective.

Mounting and Build

The lens body uses metal with glass optics. This microscope Barlow lens carries a 48mm (1-7/8 inch) thread that screws directly onto the objective of a compatible stereo zoom microscope, trinocular models included. You need no tools. Check your objective’s thread diameter before you order, because a microscope with a different thread size will not accept it.

The lens adds to your existing microscope and does not replace the main objective. Tighten it by hand until it sits snug. Wipe the glass with a lint-free cloth to keep your view sharp, and keep the lens away from the bench edge when you do not use it.

Where the WD168 Fits on Your Repair Bench

Think about where extra clearance pays off. Under your hot air station, rising heat stays farther from the objective when you lift a BGA IC. At your soldering station, you reach tiny pads for jumper lagana without your wrist bumping the lens. With a reballing kit, you place the stencil and balls with both hands free. A PCB holder keeps the board steady at this distance, and your multimeter confirms the repair when you finish.

For dead phone and charging issue jobs, you inspect the whole board first, then narrow down to the suspect IC or connector. Display problem and network issue boards follow the same pattern: wide scan, then close work. eMMC and UFS reballing jobs benefit from the same open workspace.

This WD168 microscope lens suits workshops that run several benches. Fit one lens per microscope and every technician gets the same clearance. If you want a different distance, RF4 also lists 0.5X WD165 and 0.7X WD120 auxiliary lenses. The WD168 gives the longest working distance of the three.
