Frequently Asked Questions
What magnification does the DMM-S13N-7LL3 provide?
It switches quickly between 10× and 30× using 1× and 3× paired objectives with WF10× eyepieces.
Does the DMM-S13N-7LL3 come with a light?
Yes — it has integrated dual-LED illumination, and a knob lets you use the top light, bottom light, or both for shadow-free viewing.
How large a specimen can the DMM-S13N-7LL3 handle?
It has an 88.9 mm working distance and accepts specimens up to 120 mm tall, with a reversible black/white stage plate.
How is the DMM-S13N-7LL3 different from the S13N-PL77 and S12N-PA77?
The S13N-7LL3 includes a dual-LED pole stand; the S13N-PL77 is the same 10×/30× scope without a light; the S12N-PA77 is a 10×/20× version on a flex-arm boom stand. See the comparison chart above.
