January 20, 2007:
Boston Micromachines Corp.
have announced upgraded products
for wavefront correction and wavefront sensing,
ahead of the
Photonics West 2007
conference in San Jose, California, where both are presenting exhibits.
Boston Micromachines has announced the availability of an enhanced
version of its flagship
MEMS-based deformable mirror.
The new version of the 140-actuator mirror has an increased actuator
stroke of 6µm (up from 3.5µm),
to meet the requirements of retinal imaging systems.
The increased stroke will also broaden the mirror's use in biological
Retinal imaging AO systems can provide a clear view of the retina through the distorting effects of the intervening tissue, and can help in the early detection of ocular diseases such as glaucoma, diabetic retinopathy and age-related macular degeneration, but the imaging systems require a particularly high level of wavefront correction, especially for older eyes.
"The ever increasing strokes in deformable mirrors, such as the 6µm achieved with BMC's new Multi-DM, will allow for deeper AO corrected imaging in
biological specimens, more effective correction when used at longer wavelengths,
and improved performance specifications in systems such as
the Adaptive Scanning Optical Microscope (ASOM)
and other AO based imaging systems," said Ben Potsaid,
Research Scientist at the
Center for Automation Technologies and Systems (CATS)
Rensselaer Polytechnic Institute (RPI).
The mirror's 3 kHz frequency capability enables high speed real-time imaging, and its 6mm aperture is well matched to the diameter of the dilated pupil.
In a separate announcement, Imagine Optic has presented the latest version of its HASO Shack-Hartmann wavefront sensor, the HASO™3, along with an upgraded version of the wavefront sensor's ASO™v3 software suite.
Imagine Optic is also introducing three new products aimed at consumer electronics manufacturers. The new
Both companies are exhibiting at Photonics West 2007, North America's largest commercial exhibition on optics, lasers, biomedical optics, optoelectronic components, and imaging technologies. The exhibition, in San Jose, California, runs from the 23rd to the 25th January 2007.
