Answers Built for Laser System Integration

ERDI develops pulsed laser sources, laser rangefinder modules, laser designator hardware and supporting optoelectronic assemblies for OEM integration. Current platforms include erbium-glass sources and 1535 nm rangefinders, 905 nm ranging modules, and 1064 nm ranging and designation systems. The released datasheet defines the scope and performance of each model.

The engineering scope can cover source and resonator design, coating specification and verification, transmitter and receiver optics, detector electronics, pulse drive and timing, embedded control, mechanical packaging and thermal design. The exact manufacturing route, verification depth and deliverables are defined for each released product or custom program.

Work begins with a requirements review covering the target and atmosphere, required range and accuracy, repetition rate, wavelength, host optics and window, electrical interface, mechanical envelope, thermal limits and acceptance method. Mandatory requirements are separated from preferences, and open assumptions are recorded before a prototype configuration is released.

A prototype verifies architecture, interfaces and integration assumptions. A production release also requires controlled drawings, approved materials, assembly instructions, inspection points, test limits and configuration records. Prototype observations become production commitments only when they are incorporated into the approved technical and commercial documents.

The wavelength is selected for the complete application. A 1535 nm architecture is often considered for compact, eye-safety-oriented ranging with InGaAs detection. A 905 nm architecture can suit compact and cost-sensitive ranging with silicon detectors. A 1064 nm architecture is common in higher-energy ranging and designation systems. Detector response, source energy, coatings, atmospheric behavior and final-product laser safety all belong in the decision.

Received signal depends on target area and reflectance, atmospheric transmission, beam divergence, receiver aperture, optical loss, detector sensitivity and the detection threshold. A range value is meaningful only when the target, visibility, repetition rate, detection logic and acceptance conditions are stated.

No. Wavelength alone does not establish the safety class. Accessible emission, pulse energy, divergence, repetition pattern, aperture and operating modes are part of the assessment. The final equipment manufacturer remains responsible for evaluating and labeling the completed laser product under the applicable standard and intended-use conditions.

Depending on the model and project stage, ERDI can provide a controlled datasheet, interface definition, connector information, mechanical drawing, STEP model, mounting guidance and integration notes. The document revision and ordered connector configuration should be confirmed before the host design is released.

Model-dependent options may include connector, reporting, trigger, repetition-rate and communication changes. TTL, RS-422, RS-232, CAN and other interfaces are not universal across the catalog. Voltage levels, timing, protocol, pinout and fault behavior must be agreed in the controlled product specification.

The component-specific inspection plan may include identity and revision, supplier documentation, critical dimensions, optical surface condition, coating evidence, PCB and electronic component checks, connector condition and storage-life controls. Critical characteristics are tied to the applicable drawing or purchasing specification.

Coating requirements are defined by wavelength band, angle of incidence, substrate, transmission or reflection target, polarization where relevant, environmental exposure and cosmetic limits. Verification can use spectral records, witness samples, visual inspection and dimensional or surface checks according to the product control plan.

Controlled work instructions define cleanliness, assembly sequence, torque or bonding requirements, electrical checks and optical alignment. Calibration verifies model-specific range or output parameters against defined references. Final acceptance identifies the tested configuration, test conditions and applicable limits.

Workmanship requirements are agreed by product and contract. Where requested, acceptance criteria can reference applicable documents such as IPC-A-610 and J-STD-001. A reference does not mean that every catalog product is certified to every class or revision.

No blanket claim applies. MIL-STD-810 describes environmental tailoring rather than one universal test profile. Applicable methods, severities, mounting, operating state and acceptance criteria must be stated in the model specification or project qualification plan.

Lifetime depends on architecture, pulse energy, repetition rate, duty cycle, temperature, drive conditions and the acceptance definition. A 30-million-pulse requirement is binding only when it appears in the controlled product specification or quotation together with the test profile.

Depending on the program, records can link the released configuration to material lots, key components, process travelers, calibration status, inspection results, test data and final release. Required serial-number, lot and document depth should be agreed before production because record scope affects cost and lead time.

A proposed change is evaluated for form, fit, function, interfaces, qualification status and supply continuity. Customer notification or approval requirements should be written into the contract or quality agreement. Released drawings, bills of materials, firmware and test procedures remain revision-controlled.

Feasible options may include range profile, repetition rate, communication protocol, connector and harness, mechanical envelope, mounting interface, firmware behavior, reporting mode and documentation package. Feasibility is reviewed against safety, performance, qualification, schedule and recurring-volume requirements.

Provide the model or performance requirement, application, prototype and annual quantities, target and environment, interface and mechanical constraints, requested qualification, document package, destination country and required delivery timing. Mark mandatory requirements separately from preferences so technical and commercial assumptions can be stated clearly.

Standard products may be available in prototype quantities, while a custom product can require engineering, tooling or a minimum production lot. The quotation identifies sample quantity, recurring quantity breaks and any non-recurring engineering charges.

Lead time begins after the technical scope, configuration, commercial terms and required customer inputs are confirmed. It depends on material availability, customization, document approval, qualification and production quantity. The accepted quotation or order confirmation is the controlling schedule reference.

Sample or prototype orders are common for integration. The sample configuration, documentation and acceptance method should match the intended evaluation. Production pricing and lead time are reviewed separately after the configuration is frozen.

Submit the requested change in writing. ERDI reviews its impact on materials, work in progress, tooling, verification, price and schedule before acceptance. No specification or configuration change is effective until both parties confirm the revised technical and commercial documents.

The standard package is model-dependent. It may include the current datasheet, interface information and shipment documents. Inspection data, certificates of conformity, serial-number lists, special test reports or source-inspection records must be identified in the quotation if required.

Packaging is selected for the product's optical, electrostatic, mechanical and moisture sensitivity. Shipping method, Incoterm, insurance, export documentation and destination requirements are confirmed in the order. Tracking information is provided when the selected carrier supports it.

Photograph the unopened package, shipping label, internal protection and affected product. Keep all packaging and notify ERDI and the carrier promptly. Do not power or disassemble an optically or mechanically damaged unit until the technical team provides handling instructions.

Warranty duration, coverage and remedy are stated in the accepted quotation or contract. Coverage normally depends on operation within the specified electrical, optical, mechanical and environmental limits. Misuse, unauthorized modification, contamination, incorrect installation and damage outside the agreed conditions may be excluded.

Contact ERDI before returning hardware. Provide the model, serial number, operating history, host configuration, fault description, logs and photographs when available. ERDI will issue return instructions, evaluate the unit and report the recommended repair, replacement or investigation path under the applicable terms.

Yes. Efficient troubleshooting usually requires the host schematic or interface description, supply waveform, command log, trigger timing, mechanical mounting, optical-window details, target conditions and a repeatable fault description. Support can include remote review, controlled tests and a documented corrective-action plan.
