High Quality Rigid Optical Endoscope with 4mm Lens and 420mm Length for Medical Diagnosis

Yeah, we got your inquiry about the rigid optical endoscope, and I can confirm the R4420 is what we've been sending out for ENT work — the 4mm lens and 420mm probe length are pretty much the standerd for most sinus and laryngeal exams, and the 90-degree side view gives you that wide field without having to reposition too much.

It's autoclavable, which is what most clinics want, and the IP67 rating means you can dunk the whole thing for cleaning without worrying about damage — we've had a few buyers ask about that specifically, and it's held up fine in testing, though I'd still avoid prolonged soaking in harsh disinfectants just to be safe.

The adjustable LED light source is actually built into the handle, so you don't need an external cable or adapter, which cuts down on setup time a bit — brightness is controlled by a small wheel, and it's bright enough for most routine diagnostics, but if you're doing something like a deep nasopharynx scope, you might want a supplemental light source (usually 2-4 weeks for those).

CE certification is in place, and we can provide the COA and sterilization validation docs with each shipment — the stainlss steel body is medical grade, but what it's not suited for is heavy orthopedic work or anything requiring a flexible tip, so keep that in mind if your appliction is more surgical than diagnostic.

10 units or so is our typical MOQ, but our company can do smaller trial orders if you're just evaluating — lead time is roughly 20 days from order confirmation, and payment terms are usually T/T or L/C at sight, so just let me know which format you prefer and I'll get proforma over to you.
