Thorlabs Launches Precision Laser Diode Optics for Advanced Applications

For researchers and engineers working with laser diodes, achieving optimal beam collimation and focus is critical for high-performance applications. Thorlabs offers a comprehensive series of laser diode collimation and focus tubes designed to meet the exacting requirements of precision optics.

The Thorlabs laser diode collimation tubes provide an effective solution for controlling beam divergence. These passive laser diode mounts come pre-installed with precision aspheric optical elements, delivering exceptional collimation performance. For users requiring customized configurations, empty tube versions are also available, allowing the integration of various lenses with M9 x 0.5 or M12 x 0.5 threads.

• Pre-installed collimation optics ready for immediate use with SR9 strain relief and ESD protection cables
• High-efficiency aspheric collimation lenses with three broadband anti-reflection (AR) coating options covering 350-1700 nm spectrum
• Secure laser diode mounting using 13/32"-40 threaded retaining rings compatible with Ø5.6 mm or Ø9 mm laser diodes
• Precise focus adjustment with rotatable locking cap providing 2.5 mm (0.1") of lens travel
• Integrated components including main tube, pre-installed optics, retaining rings, and adapter sleeves
• Versatile mounting options through Ø15 mm tube compatible with various adapters

The Thorlabs laser diode focus kits feature carefully designed aspheric lens pairs for precise focusing of laser diode output beams. These systems allow fine control of focal length through adjustable lens positioning. Similar to the collimation tubes, empty versions are available for custom optical configurations.

• Adjustable focus design compatible with SR9 strain relief and ESD protection cables
• High-performance aspheric lens pairs with three AR coating options
• Secure diode mounting with 13/32"-40 threaded retaining rings
• Complete kits including main tube, optics, retaining rings, and adapter sleeves
• Flexible mounting options through Ø15 mm tube design

Thorlabs offers specialized cables designed to protect laser diodes during operation. These integrated solutions combine laser diode sockets with shielded cabling, featuring:

• 13/32"-40 external threading for compatibility with various Thorlabs laser diode accessories
• Built-in ESD protection with clamping and reverse protection diodes
• Controller-compatible options with DB9 connectors for direct connection to Thorlabs laser controllers

Users should note that these collimation and focus tubes do not include any temperature regulation or measurement capabilities. For high-power laser diode applications, additional thermal management systems are strongly recommended to prevent premature diode failure.

The systems support common Ø5.6 mm or Ø9 mm packaged low-power laser diodes and offer flexible integration with various optical mounting solutions through adapter components. Installation is facilitated by specialized tools including SPW301 and SPW801 wrenches for easy assembly and disassembly.
