| Integrated Laser and Optics System |
| |
The MOS system utilizes a pair of etalons to generate a 2-D array of parallel laser beams from a single beam laser source. All optics are rigidly mounted to reduce vibrational noise. The laser system is stabilized and temperature controlled to maximize lifetime. |

- Diode Laser Module and Custom Optics
| Specifications: |
|
| Fiber coupled, Peltier-cooled laser diode package with integrated current controller and temperature controller. |
|
| Laser Wavelength |
658nm nominal (other wavelengths available upon request.) |
| Laser Output Power |
>13 mW, measured directly at laser output. Note: All high-power beams are confined within the MOS housing even when the cover is removed for alignment. The cover is not interlocked. Direct access to the main beam is necessary during alignment. The total output power in the housing is typically less than 50 microwatts. |
| Beam Geometry |
Circular Gaussian output with integrated long focal length lens cell |
| Operation Mode |
Constant current output |
| Stability |
≤ 0.2% |

- High Performance Diode Laser Controller
Linear, low-noise diode laser controller operates in constant current mode with output power stability ≤ 0.2% typical (24 hours). Output power is current-limited with slow-start circuitry for extended diode laser life. Output power is computer controlled from threshold power to full rated output. Temperature control is factory set for 13°C and has an absolute stability of <0.2°C.

Automated Mirror Tracking with Servo Control |
| |
One application of the MOS system is monitoring curvature/stress during high temperature annealing. The thermal expansion inherent in most heater stages causes significant angular displacement of the heater stage and sample. The effect of the displacement is that the reflected beam array slowly drifts off the CCD during the temperature ramp. Compensation for this drift is made using servo-motor control of an optical flat mirror to provide fully automated tracking capability through the MOS software.

| |
|
| Viewport Mount |
| |
Black anodized flange mounts, for mounting and concealing the laser, detector, and all optics. Features include rigid construction, light tight to provide protection from the laser beam. Standard single-port, dual-port, and bench-top systems are available. k-Space also designs custom mounts to accommodate any system. (Note: In order to view the 3-D models you will need to use Internet Explorer and install e-drawings when prompted) |

|
| Computer Control Boards |
| |
Several control boards are used to interface from a host computer to the MOS system. The standard system requires three available PCI slots and two additional (PCI) slots for detector power and servo motor interfacing. |
| |
|
| |
- Scientific-Grade Analog Frame Digitization Board:
Programmable resolution scientific-grade frame grabber utilizes digital clock sync technology to provide less than ± 5ns jitter. Up to 30 Hz frame rate, no on-board memory (maps directly to host computer RAM or video RAM), runs on PCI bus as bus master. Programmable gain, offset, reference value, and video input. Utilizes speed of PCI bus to perform real-time display on computer monitor. Includes adapter cable for multiple video inputs, digital I/O, and external trigger capability.
|
|
|
| |
- Multifunction Digital and Analog I/O Board:
High-resolution, 16-bit analog I/O board for control of laser output power and monitoring laser photodiode current. Additional analog input is provided and supported in software for reading instrumentation, such as temperature controllers. A single programmable ±5V, 16-bit analog output is provided for equipment control. Requires one PCI slot.
|
|
|
| |
- Servo Control Board:
High-resolution, 8-channel servo motor control board with two servo motor amplifiers to control an automated mirror stage. Requires one PCI slot for the board and one additional slot in the riser for cable interfacing.
|
|
|
| 12-bit High-resolution Detector/Digital Framegrabber (M-HRD/U) (Optional) |
| |
The MOS system can be configured with a 1300 x 1030 pixel, 12-bit, high-resolution detector. This detector offers a CCD sensor with nearly twice the spatial resolution of our standard 768x480 detector. The increased spatial resolution and bit depth can provide nearly twice the radius of curvature detection capability. In a well-controlled experimental setup, radius of curvature detection can approach 20km or greater. The ultimate resolution of the system is, of course, dependent upon the particular configuration |
