Thorlabs - Compact Laser Modules with USB Connector
Thorlabs` USB-equipped laser modules feature a typical output power of 0.9 mW (laser safety Class 2) at a 520 nm or 635 nm typical center wavelengths. The output is collimated with a Ø3 mm round beam profile at 50 mm from the housing. These modules offer single-spatial-mode output in a compact, electrically isolated cylindrical housing and are ideal for use as alignment lasers in optical systems. The lasers are driven in constant-power mode, with feedback from an internal photodiode used to maintain the optical output power. As these diodes are not thermally stabilized, their optical output power may fluctuate slightly during operation.
Features
- 520 nm or 635 nm Typical Center Wavelength
- 0.9 mW Typical Output Power
- Collimated Output
- Ø11 mm Compact, Electrically Isolated Housing
- Constant Power Mode Operation Using Built-In Photodiode Feedback
- USB Type-A Plug-and-Play Operation
- Mounting Accessories Available
- Compatible with DS5 Power Supply (Sold Separately)
The USB Type-A connector on each laser module features a built-in, highly attenuating electrical filter to reduce noise for a more stable laser output. Also featured on the connector are a status LED, on/off switch, and laser warning information. Unlike our phono-jack-equipped laser modules and laser modules with bare wire leads, no adapters or extra connectors are needed to operate these lasers.
We recommend powering these lasers with our DS5 5 VDC power supply, which is sold separately below.
Mounting Options
The Ø11 mm housing is compatible with our line of optomechanical components through the use of various mounting adapters, as shown in the images to the right. Depending on the adapter chosen, these laser modules can be directly mounted into either internally SM1-threaded (1.035"-40) components or mechanics with a Ø1" bore. Further details on each adapter and its compatibility with our line of optomechanics can be found below.
Thorlabs also offers a Mini-Series kinematic mount for Ø11 mm laser diode modules (available below). This kinematic mount is among our smallest kinematic mounts available and features 4-40 (M3) taps for mounting onto our Ø6 mm Mini-Series Posts.
