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 sub-nanometer range and their response time lies in the microsecond range.
These new actuators have a high degree of flatness outer surface making them well suited to the mounting of optical fibres or optical sensors.
They have a higher dynamic load rating than conventional piezoelectric actuators and they are 100% vacuum compatible with no insulation outgassing.
The PICMA actuators are ideal for closed loop operation and the application of strain gauge sensors.
Typical applications include nanopositioning, fibre optic positioning, laser and component tuning, high-speed switching, scanning microscopy, active optics, micropumps, microdosage, biotechnology, high-speed valves, metrology, interferometry.
A large variety of high-speed, digital and analogue low-noise, open and closed-loop controllers (bench-top, rack-mount and OEM modules) is available to suit any need or budget. Request a free brochure from Lambda Photometrics ...
