Detailed LDR60K1 Specifications
The technical material below is retained for this model only. Do not transfer a range, pulse, interface, mechanical or safety value from another 1064 nm product.
Specifications
The tables below retain the supplied model record except for entries explicitly withheld after a comparison with the current model PDF. A value, option or condition from another model is not interchangeable. General explanations are separated from model-specific entries.
Source-review note
The old range and code-accuracy summary contains qualifiers that are not established by the current model document. Those entries are withheld pending confirmation.

Technical drawings
Evidence status: published data is not a substitute for the ordered revision, a serial-number test report or a laser-classification report. A standard mentioned in a table is not proof of third-party certification.
Model-specific conditions and limits
Conditions are retained only when the source states them. They are not reconstructed from a nominal range or wavelength.
Operating conditions
Read the value together with its qualifier
A minimum, maximum, typical value and tolerance are different kinds of statement. “≥” is a lower bound and “≤” is an upper bound; neither is an exact measurement. A nominal value without tolerance does not establish a tolerance. Preserve the units and the condition printed beside every entry.
Keep operating modes separate
If the original table lists more than one operating mode, each rate, duration and stability statement belongs to its stated mode. This page does not combine the most favorable entries into a new operating specification. A published duration is not evidence of unrestricted continuous operation.
Environment and document revision
Storage limits describe a non-operating condition and must not be substituted for powered-operation limits. A test-standard name without the method, severity, configuration and outcome is an incomplete qualification record. Request the relevant report for the exact supplied revision; do not describe a reference to a standard as a blanket certification.
Safety review
1064 nm is outside normal visual perception. A beam that cannot be seen can still be hazardous; brightness or a camera image is not a safety measurement. Laser safety assessment must address the complete product and its accessible emission, not only the source wavelength. IEC 60825-1:2014 — Safety of laser products; FDA — Frequently Asked Questions About Lasers.
Pulsed Time-of-Flight Ranging
Technical principle
Laser emission: a high-level overview
A laser combines an energized gain medium with optical feedback to produce stimulated emission. Solid-state lasers use a solid host for the active species. The wavelength name alone does not identify a particular host material, pump wavelength or cavity construction, so this page does not infer those internal parts for LDR60K1. FDA — Frequently Asked Questions About Lasers.
What a pulsed-source specification describes
Pulse energy describes energy in one optical pulse. Pulse duration describes its temporal extent under a stated width convention. Repetition rate describes how often pulses occur. These quantities must not be substituted for each other: an energy specification is not a power specification, and a rate does not describe a waveform. Electrical input power and optical output also refer to different quantities.
Beam size and angular spread are different measurements
A beam diameter applies at a specified measurement plane. Divergence describes angular spreading rather than diameter at one location. Different width definitions and full-angle versus half-angle conventions can give different numerical descriptions of the same beam. Where the model record does not identify its convention, the comparison remains incomplete. ISO 11146-1:2021 — Beam-width, divergence and propagation measurement terminology.
Accuracy, resolution and stability are separate terms
Resolution describes the reported increment or discrimination scale; accuracy concerns the difference between a measurement and a reference. Stability concerns variation over an interval or set of conditions. A small displayed increment does not by itself establish small error, and one stability metric does not establish another. The original table’s labels and qualifiers remain important even when two entries share a numerical value.
Physical explanation versus product evidence
A scientific paper can explain a phenomenon without testing this product. Its measured output, material recipe, internal geometry or performance cannot be transferred to LDR60K1. A manufacturer's published record, a unit test, a qualification report and an independent standard each answer a different question. The references below are explicitly identified by that role.
Invisible radiation and responsible documentation
Eye and skin hazards depend on exposure, not on whether an observer sees a spot. A product page is not a safe operating procedure. Applicable controls and personnel responsibilities require a qualified safety review, and the product must retain its warnings and approved instructions. OSHA — Laser Hazards.
Pulse energy describes emitted energy per pulse; its effect cannot be separated from pulse width, divergence, optical losses, receiver threshold and the stated target/atmosphere conditions. It is not a substitute for a model-specific near- or long-range acceptance test.
Source-stated application context
Application labels indicate evaluation context, not automatic fitness for a finished system.
The retained table provides a ≤0.3 mrad divergence entry and an enclosure bounded by 116 ×52 ×96 mm. It also distinguishes its ±2 m ranging-accuracy entry from the currently withheld maximum-distance field. These documented optical and package attributes are more useful than a generic family title for an initial model comparison.
Use the current LDR60K1 document for the ordered configuration and its measurement conditions. The source’s operating-temperature and storage-temperature entries are separate requirements, and the stated optical-axis terms refer to different references. This page does not turn a published environmental requirement into an independent qualification result or add a missing ranging distance.
Confirm short- and long-distance acceptance conditions
- Define minimum distance, target material, reflectance, size and incidence angle.
- Check receiver recovery, optical-axis overlap and strong-return handling at the intended near limit.
- Verify supply tolerance, peak current, grounding, interface levels, connector and timing with the ordered revision.
- For long-distance acceptance, state target geometry, visibility, weather, background and required detection probability.
- Test with the installed window, boresight, field of view, enclosure and thermal path rather than a bare module alone.
- Evaluate accessible emission, labels and failure conditions again for the finished laser product under IEC 60825-1.
Questions to resolve before design release
What optical energy quantity is stated for LDR60K1?
The current model document specifies average pulse energy ≥60 mJ. That qualifier is retained rather than converted into a minimum for every individual pulse. The same record lists 1064 ±3 nm emission and a 15 ns ±5 ns optical pulse-width entry.
Does LDR60K1 have an advertised maximum measuring distance?
The current public page does not confirm measurement range pending corrected controlled evidence. It retains a separate ±2 m accuracy entry, but accuracy is not a distance limit. Historical distance wording or another model’s target and atmospheric conditions cannot establish LDR60K1’s qualified range.
What is the LDR60K1 package class?
The record lists dimensions ≤116 ×52 ×96 mm and mass ≤680 g. Those values identify the product’s external envelope for a document comparison. A current drawing and ordered-variant information remain necessary for a formal mechanical acceptance assessment.
Are optical-axis stability and parallelism the same specification?
They describe different reference relationships in the LDR60K1 table. A stability entry concerns change, while the parallelism entry is relative to a mounting datum. Preserve the original definition for each; combining them into one alignment promise would remove information needed for a valid comparison.
Does the general beam reference certify LDR60K1’s divergence?
No. It describes measurement terminology and methods rather than an independent product test. The stated LDR60K1 beam value still depends on its model-specific definition and controlled evidence. A standards citation should not be presented as proof of an unstated measured result or safety class.
