Thorlabs' adaptive optics kits are a complete adaptive optics imaging solution, including a deformable mirror, wavefront sensor, control software, and optomechanics for assembly. These miniature, precision wavefront control devices are useful for beam forming, microscopy, laser communications, and retinal imaging. To learn more how the wavefront sensor, deformable mirror, and software operate as a closed-loop system to correct wavefront distortion, please see the various tabs on this page or the Adaptive Optics 101 white paper.

Thorlabs now offers eight variations of AO Kits. Choose from a gold- or aluminum-coated deformable mirror with 140 or 32 actuators and a 15 Hz CCD-based or 450 Hz CMOS-based Shack-Hartmann wavefront sensor. Details on all eight AO Kit options are outlined in the various tabs on this page.

* For the configurations used in the AO Kit, the frame rates will be nominally 8 Hz and 100 Hz for the CCD and CMOS sensors, respectively. For frame rates of 450 Hz with the CMOS sensor, a resolution of 180 x 180 pixels must be used. This PC hardware-dependent speed is achieved without graphical display, assumes a 5th order Zernike fit at the specified camera resolution, and minimum exposure time.

Through our partnership with Boston Micromachines Corporation (BMC), Thorlabs is pleased to offer BMC's Mini- and Multi- Deformable Micro-electro-mechanical (MEMS) based mirrors as part of our adaptive optics kits. These deformable mirrors (DMs) are ideal for advanced optical wavefront control; they can correct monochromatic aberrations (spherical, coma, astigmatism, field curvature, or distortion) in a highly distorted incident wavefront. MEMS deformable mirrors are currently the most widely used technology in wavefront shaping applications given their versatility, maturity of technology, and the high resolution wavefront correction capabilities they provide.


MEMS Deformable Mirror Structure

Our Deformable Mirrors, fabricated using polysilicon surface micromachining fabrication methods, offer sophisticated aberration compensation in easy-to-use packages. The mirror consists of a mirror membrane that is deformed by either 32 electrostatic actuators (i.e., a 6 x 6 actuator array with four inactive corner actuators for the Mini-DM) or 140 electrostatic actuators (i.e., a 12 x 12 actuator array with four inactive corner actuators for the Multi-DM). These actuators provide 3.5 μm of stroke (over 11 waves at 632.8 nm) with zero hysteresis.

Mirrors are available with a Gold (-M01) or Aluminum (-P01) reflective coating. Each is packaged with a protective 6° wedged window that has a broadband AR coating for the 400 - 1100 nm range.

 

Shack-Hartmann Wavefront Sensor

  • High-Sensitivity Model: CCS-Based, up to λ/50 RMS (WFS150-5C)
  • High-Speed Model: CMOS-Based, up to 450 Hz (WFS10-5C)
  • Wavelength Range: 300 - 1100 nm
  • Real-Time Wavefront and Intensity Distribution Measurements
  • Nearly Diffraction-Limited Spot Size
  • For CW and Pulsed Light Sources
  • Flexible Data Export Options (Text or Excel)
  • Live Data Readout via TCP/IP

Thorlabs AO Kit includes either the WFS10-5C CMOS-based wavefront sensor, or the WFS150-5C CCD wavefront sensor. These Shack-Hartmann wavefront sensors can detect distortions in the wavefront which can then be corrected by the deformable mirror.

450 Hz CMOS-Based Sensor
The Nature of CMOS technology makes it ideal for the WFS10-5C fast wavefront sensor. Because each pixel has its own electronics, CMOS sensors have an advantage in windowing, where only a portion of the signal from the sensor is read. The signal can be read quickly from only a portion of the sensor, rather than sequentially from the whole sensor, as in a CCD system. The area of interst (AOI) can thus be scaled down for higher frame rates of up to 450 Hz*. At the resolution setting used in the AO Kits, the WFS10-5C can operate at a maximum frame rate of ~100 Hz. The WFS10-5C fast wavefront sensor is included in the AOK3 and AOK4 AO Kits.

* For frame rates of 450 Hz, a resolution of 180 x 180 pixels must be used. This PC hardware-dependent speed is achieved without graphical display, assumes a 5th order Zernike fit at the specified camera resolution, and minimum exposure time.

1.3 Megapixel CCD Sensor
Our WFS150-5C 1.3 Megapixel wavefront sensor has a higher wavefront sensitivy of up to λ/50 RMS due to the increased spatial resolution of the CCD sensor (4.65 µm pixel pitch). This sensor operates at a frame rate of 15 Hz, and is included with the AOK1 and AOK2 AO Kits.
