Supplier of 5-pin laser diode test socket
Thorlabs, JC CHERRY, Mouser Electronics, and ZeQun Technology are key suppliers of 5-pin laser diode test sockets suitable for various TO-style packages.
Thorlabs
Thorlabs offers a wide range of laser diode sockets compatible with Ø3.8 mm, Ø5.6 mm, Ø9 mm, and TO-5 laser diode packages. Their sockets feature gold-plated BeCu contacts, RoHS compliance, and are available individually or in packs of 5, 25, or 100. Some models include strain-relief assemblies and ESD protection, making them suitable for repeated testing and integration with laser diode drivers. Thorlabs also provides sockets with polarization dots for alignment purposes and small PCBs with Schottky and Zener diodes for voltage protection .
JC CHERRY
JC CHERRY supplies sockets compatible with TO-18, TO-46, TO-52, and TO-72 laser diode packages. They also offer cable-equipped sockets designed for fiber-coupled devices (FCD), which can be useful for testing and connecting laser diodes in optical systems .
Mouser Electronics
Mouser Electronics stocks Laser Diode Socket IC & Component Sockets, providing inventory, datasheets, and pricing for various socket types. This is a convenient option for sourcing standard 5-pin sockets with detailed specifications and bulk ordering options .
ZeQun Technology
ZeQun Technology specializes in laser diode sockets for TOSA, BOSA, and ROSA components, designed for packaging and testing. Their sockets use gold-plated copper pins with low contact resistance and long service life. ZeQun's process technology allows for high insulation and durability, making their sockets suitable for manufacturers requiring reliable and long-lasting test solutions. They also offer universal pin lengths to accommodate different laser diode pins .
Summary
For 5-pin laser diode test sockets, Thorlabs and JC CHERRY are suitable for standard TO-style packages, Mouser Electronics provides easy access to datasheets and bulk orders, and ZeQun Technology offers high-durability sockets for optical component manufacturing. Depending on your requirements—such as package type, durability, or ESD protection—these suppliers provide a range of options for testing and integration.
