Infrared Imaging : The best gets better
Viewing infrared wavelengths between 0.4-1.5microns, the converted image produced by the new 7215 is now brighter and offers edge to edge sharpness.
Infrared Imaging at Telecomms Wavelengths
The widely used Electrophysics 7290A Micronviewer Infrared camera has now been enhanced with increased sensitivity at both 1310nm and 1550nm.
This means that polymer-film insulation is no longer required, and the actuators can operate reliably at temperatures ranging up to 150C - much higher than the 80C limit found with conventional multilayer actuators.
The ceramic insulation means that PICMA actuators are significantly less susceptible to environmental influences than other piezoelectric actuators and therefore have a much longer lifetime, especially when used under extreme conditions such as high humidity.
Their positioning resolution is in the subnanometre range and their response time lies in the microsecond range.
Further advantages over conventional piezoelectric actuators include: excellent flatness of the outer surfaces, making them extremely well suited for the mounting of optical fibres or optical sensors; higher dynamic load rating; higher temperature stability; longer lifetime, even under extreme conditions; 100% vacuum compatibility, with no insulation out-gassing; and the actuators are extremely well suited to closed-loop operation and application of strain gauge sensors.
Typical application areas include nanopositioning, fibre optics, laser and component tuning, high-speed switching, scanning microscopy, active optics, micropumps, microdosage, biotechnology, high-speed valves, metrology and interferometry.
A large variety of high-speed, digital and analogue low-noise, open and closed-loop controllers (bench-top, rackmount and OEM modules) are available to suit any need or budget. Request a free brochure from Lambda Photometrics ...
