pdf
Beacon together with Trestles Ti:sapphire oscillator, second and third harmonic
generators. Femtosecond optical gating (FOG) method gives best temporal
resolution in light-induced fluorescence lifetime measurements. The resolution
is determined by a temporal width of femtosecond optical gate pulse and doesn't
depend on the detector response function. Sum frequency generation (also called
upconversion) in nonlinear optical crystal is used as a gating method in the
Beacon femtosecond fluorescence kinetic measurement system. We offer
Beacon-DX for operation together with Ti: sapphire femtosecond oscillators
and Beacon-DA for operation together with femtosecond amplified pulses.

Hatteras-D
femtosecond transient absorption data acquisition system
Future nanostructures and biological nanosystems will take
advantage not only of the small dimensions of the objects but of the
specific way of interaction between nano-objects. The interactions
of building blocks within these nanosystems will be studied and optimized on
the
femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar
Photonics, Inc. Thus we put a lot of our efforts and resources into the
development of new Ultrafast
Dynamics Tools such as our Femtosecond Transient Absorption Measurements
system Hatteras. Whether you want to
create a new photovoltaic system that will efficiently convert photon energy
in charge separation, or build a molecular complex that will dump photon energy
into local heat to kill cancer cells, or create a new fluorescent probe for
FRET microscopy, understanding of internal dynamics on femtosecond time scale
is utterly important and requires advanced measurement techniques.Reserve a

Wavefront Sensors: ShaH Family
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 LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype 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. This makes it possible to apply such a
wavefront sensor in astronomy, remote sensing, etc.
