Near Field Scanning Optical Microscope is latest system from Mad City Labs |
|||||||||||||
|
Mad City Labs' Near Field Scanning Optical Microscope System (NSOM) is based on their versatile RM21™ microscope platform. It offers NSOM, SPM, and fluorescence optical microscopy techniques in a single package. The NSOM combines Mad City Labs' successful SPM resonant probe, the MadPLL® phase lock loop controller, and several of the company's precision positioning elements. For example, the NSOM includes six axes of motorised positioning for the sample and NSOM probe, and three axes of closed loop nanopositioning for exceptional position resolution and accuracy. Other key items supplied are: a 635 nm laser excitation source with fibre launch, a 100x 1.25 N.A. oil immersion objective lens, an avalanche photodiode detector, a CMOS alignment camera, and various tuning fork probes (image above). The microscope's versatile design allows researchers to configure the instrument for many different optical microscopy techniques such as:
The NSOM operates in aperture mode, supporting illumination; collection; illumination and collection; reflection and reflection collection, with shear force feedback. Mad City Labs supply a LabVIEW™ based software package which automates the motion control features. For details about this and other products from Mad City Labs, please contact us. |

Energetiq's EQ-400 offers the highest radiance available in a broadband white light source |
|||||||||||||
|
Continuing the development of the highly successful Laser-Driven Light Source (LDLS) technology, Energetiq's 5th generation EQ-400 offers the highest radiance and irradiance available in a truly broadband white light source.
The EQ-400 features a compact lamp house, with clean construction that ensures long life and the ultimate in stability. With a 170 to 2100 nm wavelength range, and a choice of source dual-beam output or a single-beam output with retro-reflector, the EQ-400 is flexible for a broad variety of applications. For details about the EQ-400 and other LDLS light sources Energetiq manufacture, please contact us. |

Non-contact Visible Fault Location in fibre added to OZ Optics range |
|||||||||||||
OZ Optics has expanded its range of Visible Fibre Optic Fault Locators with the addition of a benchtop non-contact tester, the ideal solution for inspecting devices with no connectors on the fibre ends.
Pulse modulation aids in locating faults under high ambient light conditions and improves battery life. 2 Hz modulation is easy to detect with the naked eye, while 270 Hz and 2 kHz pulse modulation modes are used for fibre identification by detectors. For more information, please contact us. |

Laser Servo Lock technology demonstrated by Vescent |
|||||||||||||
Vescent Photonics have two videos demonstrating the robustness of their D2-125 servo-loop controller in maintaining lock. The D2-125 Laser Servo is designed for low-noise servo control of lasers and other experimental systems. The PI2D loop filter, with two-stage integral feedback, provides tight locking to cavities and atomic/molecular transitions. The D2-125 provides full user-control over the loop-filter parameters, enabling servo-loop optimisation for a wide variety of systems such as: acousto and electro-optic actuators, voice coils, piezo actuators, temperature controllers, and so on.
Lock Guard™ Option If your delicate laser experiment keeps losing its lock, contact us for more information. |
