They are not reconstructed from a nominal range or wavelength.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003eIs 1064 nm visible to the eye? It is infrared rather than ordinary visible light. Absence of a visible beam does not indicate absence of emission or hazard. Do not use visual appearance as an exposure assessment.\u003c\/p\u003e\n\u003cp\u003eDoes the wavelength determine the laser class? No. Product classification depends on accessible emission and the relevant assessment conditions. The wavelength is one input, not a classification certificate.\u003c\/p\u003e\n\u003cp\u003eDoes pulse energy describe electrical consumption? No. Pulse energy is optical energy per pulse. Supply consumption is an electrical quantity and belongs to its own operating condition in the model documentation.\u003c\/p\u003e\n\u003cp\u003eAre accuracy and resolution interchangeable? No. A reporting increment is not a bound on measurement error. Read each field under its own definition and test conditions.\u003c\/p\u003e\n\u003cp\u003eCan full-angle and half-angle divergence be compared directly? Not without identifying the convention. If the released record does not state it, request the measurement definition rather than silently choosing one.\u003c\/p\u003e\n\u003cp\u003eCan the best figures from different operating modes be combined? No. A rate, duration or stability condition belongs to the mode to which it is assigned. Combining unrelated conditions creates a new, unsupported specification.\u003c\/p\u003e\n\u003cp\u003eDoes a cited standard prove certification? No. A citation identifies a framework or test method. Certification or completed qualification needs the relevant report and an explicit statement of the assessed product configuration.\u003c\/p\u003e\n\u003cp\u003eWhat does a “typical” value mean here? It describes the source record’s representative value, not a newly guaranteed upper or lower limit. A typical entry must remain labeled typical.\u003c\/p\u003e\n\u003cp\u003eCan storage temperature be used as the operating range? No. Non-operating storage and powered operation are different states. Preserve both entries and their qualifiers.\u003c\/p\u003e\n\u003cp\u003eDoes a reference paper establish this product’s internal material or design? No. General laser physics is not a bill of materials. Internal materials and construction require a controlled model source.\u003c\/p\u003e\n\u003cp\u003eWhat should happen when a source unit or field is incomplete? Leave the uncertainty visible and obtain a corrected controlled document. Do not infer a missing unit, test condition or option from the product name.\u003c\/p\u003e\n\u003cp\u003eWhere are the sources for this page? The Technical Downloads area contains the model document. The bibliography separates product evidence from general standards and safety information; neither replaces a unit-specific test record.\u003c\/p\u003e\n\u003cp\u003eENGINEERING REFERENCES\u003c\/p\u003e\n\u003cp style=\"font-size: 13px; color: #666;\"\u003eContent aligned with the ERDI 1064 nm product documentation for LDR40K1.
