Product Description
Luxo STAYS® Lenses for KFM, LFM, WAVE & Circus Magnifiers
Add quick, tool-free secondary magnification to Luxo illuminated magnifiers. Available in 4-, 6-, and 10-diopter options, each STAYS lens attaches directly to the primary lens via a silicone gasket—simply moisten and press into place. The compact 2" lens (≈2.5" including gasket frame) maintains optical clarity while increasing total magnification and reducing working distance for close-up inspection. STAYS lenses are specified for Luxo KFM LED/KFM, LFM LED, WAVE LED/WAVE+Plus, and Circus models, making them a versatile add-on for electronics assembly, medical and dental work, precision manufacturing, and QA/QC tasks.
Applications
Electronics manufacturing & rework
- Fine-pitch solder inspection, SMD rework, PCB trace evaluation.
- Incoming QA and sample failure analysis with higher total magnification.
Medical, dental & laboratory
- Chairside and benchtop visualization where added power improves accuracy.
- Specimen prep and device assembly under controlled lighting/magnification.
Jewelry, watchmaking & art conservation
- Stone setting, movement repair, and restoration work requiring close focus.
Industrial QA/QC & metrology
- Dimensional checks, surface finish inspection, and defect characterization.
Features
- Snap-on convenience: Silicone gasket provides reliable suction—no tools required.
- Three optical powers: 4D, 6D, and 10D variants expand your magnifier’s use cases.
- Verified compatibility: KFM LED/KFM, LFM LED, WAVE LED/WAVE+Plus, and Circus families.
- Compact footprint: 2" clear aperture (≈2.5" with frame) preserves field of view.
- Predictable working distance: Published combinations of total magnification and focal length help users pick the right lens for the job.

FAQs
Q1: Which Luxo magnifiers are compatible?
KFM LED/KFM, LFM LED, WAVE LED/WAVE+Plus, and Circus models.
Q2: How do I install a STAYS lens?
Moisten the silicone gasket and gently press the lens onto the primary lens to create suction. No tools required.
Q3: What size is the lens/viewing size?
Clear lens is 2" diameter (≈51 mm); ≈2.5" including the silicone frame.
Q4: How do the 4D/6D/10D options change working distance?
Typical working distances (with 3D/3.5D vs 5D primaries) are ≈6"/4" (4D), ≈4"/3.8" (6D), and ≈2.9"/2.6" (10D).
Q5: What total magnification should I expect?
See the table above for published combinations by model; for example, a 5D primary plus 10D STAYS yields ≈4.75× total.
Ordering
Select the diopter that meets your working-distance and magnification needs (see chart). Verify your base magnifier model (KFM/LFM/WAVE/Circus) and add the appropriate STAYS lens to cart.
