    Contact & Inquiry FAQ

    Before You Write to Us

    Can we sign an NDA before I send drawings?
    Standard practice: NDA before any drawing exchange, template on request, tooling stored free for 5 years. Files are stored against the inquiry record, shared only with the engineers assigned to your project, and never sent to third parties. Ask for the NDA template in the message field. More in the custom optics process.
    What should I prepare so the first quote is substantive?
    Five things speed the first quote: (1) sensor model & target size, (2) working distance & field of view, (3) target performance (MTF, distortion, IP or sterilization), (4) environment, (5) annual volume & program horizon. Missing pieces? Send it anyway — our engineers ask the right questions back.
    Who actually replies, and how fast will I get a price?
    Engineering-trained sales first; custom projects are escalated to the optical engineers who will own your design — with founder-level review when tolerances or schedules are at stake. Catalog quotes and sample availability come back within one business day; custom specs get a feasibility first-pass within 48 hours, then a quotation once the envelope is agreed.
    What file formats can I upload — and are they safe?
    PDF, DOCX, XLSX, STEP, DWG, ZIP, JPG, PNG up to 10 MB. Files are stored against your inquiry, visible only to the assigned engineers, never forwarded to third parties.
    My project is not ready for an RFQ — should I still write?
    Send the problem, not the spec. Describing your inspection task is enough for a first feasibility conversation — see our inspection solutions by industry.
    Do you sell to individuals or only companies?
    B2B only: equipment manufacturers, medical and NDT brands, integrators. We do not sell retail or single-unit consumer orders.
    Form, email, or WhatsApp — which should I use?
    The form routes you fastest (structured fields feed engineering directly). Email works for thread-based conversations; WhatsApp for scheduling video factory tours. All channels carry the same one-business-day promise.
    Can I get a catalog instead of a quote?
    Yes — choose “Not sure / Multiple lines” in Product Line and write “catalog” in the message. The first reply includes the matching family overview: FA machine vision, M12 / S-mount, telecentric, line scan, liquid autofocus, endoscope, thermal imaging, wide angle, and custom OEM.
    Can we meet at a trade show or exhibition?
    We exhibit at selected machine vision and medical manufacturing shows; the upcoming schedule is shared on request.
    What time zone are you in — when can we talk?
    China Standard Time (UTC+8), Monday to Friday. For US time zones, morning inquiries land in our next morning; video calls are scheduled to overlap your afternoon.
    Do you respond to inquiries in languages other than English?
    English is the working language for all quotations and engineering documentation. We can coordinate calls with Chinese-speaking engineers when your team prefers it; written records stay in English for audit clarity.
    What if my inquiry is for a competitor analysis or student project?
    We support genuine B2B evaluations and thesis-grade research with published datasheets and factory photos; detailed internal test data requires a business relationship and NDA. See also our engineering insights.
    Prefer Email? Or Visiting?

    Write Directly — or Come See the Line

    If forms are not your style, email sales@lensmindpro.com with your sensor spec or target image — the same one-business-day promise applies. Prefer feet on the floor? On-site audits at our Hangzhou factory and scheduled video tours are both welcome.
