Nanomechanical viscoelastic imager
Oxford Instruments’Asylum Research has announced a new nanomechanical imaging technique, AM–FM viscoelastic mapping mode, for its entire line of Cypher and MFP-3D atomic force microscopes. It quickly images viscoelastic properties, including storage modulus and loss tangent, with nanoscale spatial resolution. Suitable for quantitative nanomechanical measurements on materials such as polymers, composites, biomaterials, ceramics, and metals, it operates using two cantilever resonances simultaneously. The first resonance is used for amplitude modulation (AM), while a higher resonance mode is operated in frequency modulation (FM). At resonance, the cantilever frequency and phase respond sensitively to changes in sample properties such as stiffness, adhesion, and loss tangent.

Coated laser optics
Coated laser optics are used to optimize the characteristics of an emitted laser beam. Since losses are produced at each glass surface, the number of optics should be kept to a minimum. To keep that number low, Laser Components now offers laser optics with complex coatings on both the front and the back. Coating designs are manufactured on user request; many combinations are possible. Laser optics coated on both sides are often used in resonators and polarizers. Optics with a dichroic coating on the front are useful for resonator applications; for example, a coating highly reflective for 1064 nm simultaneously allows the passage of pump light. The back can be highly or partially reflective for the same or another wavelength. Optics with two-sided polarization coatings are needed when the polarization effect has to be increased and the highest extinction ratios that are required cannot be achieved with an optic with one-sided coating. It is also possible to combine a polarization coating on one side and a mirror coating on the other. Laser Components USA Inc, 9 River Road, Hudson, NH 03051, http://www.lasercomponents.com
