Product Specifications

Technical details and manufacturing context for Mounting Housing

Definition

The mounting housing is a critical component in laser diode assemblies that serves multiple functions: it provides precise mechanical positioning and alignment of the laser diode, offers structural support and protection, facilitates heat dissipation through thermal interfaces, and often includes electrical connections or isolation features. It ensures the laser diode maintains optimal optical alignment and thermal stability during operation. The housing is typically manufactured from materials such as aluminum alloy, copper alloy, stainless steel, or ceramic, selected based on thermal conductivity, mechanical strength, and electrical insulation requirements. Key parameters include operating temperature range of -40 to 85 °C, thermal resistance of 0.5 to 1.5 K/W, flatness of ≤0.05 mm per ISO 1101, surface roughness of Ra 0.8–1.6 μm per ISO 4287, electrical insulation resistance of ≥100 MΩ at 500 V DC per IEC 60127, dielectric strength of ≥1.5 kV/mm per IEC 60243, and IP rating of IP54–IP65 per IEC 60529. The housing also features mounting hole diameters for M2.5–M4 screws, center distance tolerance of ±0.05 mm per ISO 2768-m, and weight ranging from 15 to 60 g. Operating humidity is 5–95% RH non-condensing. These values are reference ranges and must be verified for the specific model and application. The mounting housing is designed to maintain optical alignment and thermal stability, but its performance depends on proper installation, torque, and thermal interface material. Regular inspection for signs of wear, corrosion, or loosening is recommended. For procurement, verify compliance with relevant standards and confirm model-specific specifications with the legal manufacturer or supplier.

Working Principle

The mounting housing operates by physically securing the laser diode in a fixed position relative to other optical components. It typically uses precision-machined surfaces or alignment features to ensure accurate optical axis alignment. Thermal management is achieved through direct contact with heat sinks or integrated cooling channels. Electrical isolation or connection is provided through insulated mounts or integrated connectors. The housing's design ensures that the laser diode remains stable under varying thermal and mechanical loads, preventing misalignment and overheating. Proper torque on mounting screws and the use of appropriate thermal interface materials are critical for optimal performance.

Frequently Asked Questions

What materials are used for the mounting housing?

The mounting housing can be made from aluminum alloy, copper alloy, stainless steel, or ceramic. The choice depends on thermal conductivity, mechanical strength, and electrical insulation needs. For example, aluminum alloy 6061-T6 is listed as a material grade with good thermal conductivity.

What is the operating temperature range?

The operating temperature range is -40 to 85 °C. Exceeding these limits may degrade seals and solder joints. Always verify the specific model's temperature limits with the manufacturer.

How is thermal resistance specified?

Thermal resistance is specified as 0.5 to 1.5 K/W. Lower values indicate better heat dissipation. This parameter is crucial for maintaining thermal stability of the laser diode.

What standards apply to the mounting housing?

Relevant standards include ISO 1101 for flatness, ISO 4287 for surface roughness, IEC 60127 for electrical insulation resistance, IEC 60243 for dielectric strength, and IEC 60529 for IP rating. These are reference standards for verification; confirm compliance with the supplier.
