Multi-Element Tube System
• Designed for System Instrumentation and OEM Applications in Mind
• Easier Lens Spacing and Better Alignment than Traditional Tube Systems
• Supports a Wide Variety of Optical Component Diameters and Thicknesses
TECHSPEC® Multi-Element Tube System is designed to simplify building optical assemblies. Featuring a dual tube
construction, the system provides easy and accurate lens spacing and alignment while ensuring a solid construction
for harsh environment applications. Outer Tubes de ne the overall system length, while Inner Optic Mounts
(available to mount a single or a pair of optical components) ensure appropriate spacing between the optical
components. The Inner Optic Mounts easily position along the Outer Tube’s optical axis and are available for optical
component diameters between 5.0 and 25.4mm. TECHSPEC® Multi-Element Tube System is ideal for system
instrumentation and OEM applications.
Note: Our specially designed Multi-Element Tube Spanner Wrench (#13-567) is highly recommended to move
Inner Optic Mounts back and forth smoothly. The hollow design enables transmission of output beam, while
adjusting lens positions.
Designed for system instrumentation and OEM
applications in mind
Application Example: 3X Beam Expander System
Our TECHSPEC® Multi-Element Tube
System can hold many di erent diameters of
optics with our Inner Optic Mounts. This allows
for the creation of very compact optical
systems. For example, the optical system to
the right is a 3X beam expander created with
the Multi-Element Tube System: its overall
size is 31.75mm Dia. x 50.0mm length.
With the optional Multi-Element Tube Spanner Wrench, the lens spacing can be
easily adjusted, enabling the beam expander to work over a broad spectral range
rather than being optimized for a single laser wavelength.
TECHSPEC® Multi-Element Tube System provides a variety of accessories
for optimizing your optical system’s performance or for supporting system instrumentation
and OEM applications. Optional Inner Spacer Rings and Inner
Spacer Tubes are available with di erent thicknesses to place between the Inner
Optic Mounts. Once the correct spacing length between your Inner Optic
Mounts is determined, you can simply add the appropriate spacer accessories to
control the distance. The system’s modularity and array of standard parts allow
for rapid prototyping and volume production.
