Lumentum 21173561 Ultra Helium-Neon (HeNe) Laser Head Assembly – 1108P-0082 / JDSU 21105356

mrad. These are family-reference specifications and should be verified against the exact 1108P-0082 configuration before being treated as guaranteed specifications of this individual assembly.

The laser head is designed with a cylindrical housing that supports mechanical integration into compatible optical systems. Its mounting arrangement helps maintain the required positioning within the host equipment. The electrical interconnection allows the laser head to operate with an appropriate compatible power supply and associated equipment control system.

The Lumentum 21173561 model identification is particularly useful for spare-part procurement and maintenance. The additional 1108P-0082 and JDSU 21105356 references provide further identification information for technicians searching for a compatible replacement. These identification numbers should be compared with the original equipment documentation before ordering.

This laser assembly may be considered by industrial maintenance departments, optical laboratories, scientific equipment service providers, precision measurement facilities, and companies involved in the repair and refurbishment of laser-based instruments.

The 632.8 nm red laser output of the 1108P family makes helium-neon laser technology suitable for a range of optical applications. These include interferometric measurements, optical alignment, dimensional inspection, calibration procedures, and other measurement processes where a stable visible laser reference is required.

The assembly's mechanical construction and electrical connections are important considerations when replacing an existing laser head. Before installation, users should verify the mounting dimensions, connector arrangement, power supply compatibility, output characteristics, and optical alignment requirements. Using an incompatible power supply or incorrect electrical configuration can damage the laser assembly.

The physical condition of the laser head should also be evaluated before installation. The optical aperture, cylindrical housing, electrical connections, mounting brackets, and cables should be inspected for signs of physical damage. Functional testing should be performed using the correct power supply and appropriate laser safety procedures.

The Lumentum 21173561 Ultra Laser Head Assembly is a specialized component for compatible optical and laser systems. Its manufacturer identification, model number, associated JDSU part number, and 1108P family reference make it a useful identification option for businesses sourcing industrial laser replacement components.

Whether required for equipment maintenance, replacement of an existing optical source, or restoration of compatible laser instrumentation, this Lumentum laser head offers a dedicated optical assembly for suitable applications. Buyers should verify the exact model configuration and technical specifications before purchasing to ensure compatibility with their equipment.

Laser equipment must always be handled by qualified personnel. Appropriate protective eyewear, laser safety procedures, equipment interlocks, and manufacturer-recommended installation instructions must be followed. Never look directly into the laser aperture or expose the eyes to the laser beam.
