San Diego, CA- A family of ShaH wavefront sensors represents recent progress of 
Del Mar Photonics in Shack-Hartmann-based technology. The performance of 
Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays 
used. Del Mar Photonics developed a proprietary process of lenslet 
manufacturing, ensuring excellent quality of refractive lenslet arrays. The 
arrays can be AR coated on both sides without interfering with the micro-lens 
surface accuracy. Another advantage of the ShaH wavefront sensors is a highly 
optimized processing code. This makes possible real-time processing of the 
sensor data at the rate exceeding 1000 frames per second with a common PC. Due 
to utilizing low-level programming of the video GPU, it is possible to output 
the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame 
rate. This mode is favorable for controlling modern liquid crystal on silicon (LCOS) 
wavefront correctors.
The family of ShaH wavefront sensors includes several models, starting from 
low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed 
model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor 
with cooling down to -100°C. Del Mar Photonics wavefront sensors are developed 
for use in astronomy, remote sensing, and high power laser beam optimization as 
well as for variety of applications in life sciences. For additional information
