AOTF Infrared Spectrometer
Del Mar Photonics offer a handheld
infrared spectrometer based on the
acousto-optic tunable filter (AOTF). This instrument is about the size and
weight of a video camera, and can be battery operated. This unique, patented
device is all solid-state with no moving parts. It has been sold for a wide
variety of applications such as liquid fuel analysis, pharmaceutical analysis,
gas monitoring and
plastic analysis.
Miniature AOTF infrared spectrometer uses
a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters
the crystal, and is diffracted into specific wavelengths. These wavelengths are
determined by the frequency of the electrical input to the crystal. Since there
are no moving parts, the wavelength scanning can be extremely fast. In addition,
specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the
hardware. After the infrared radiation reflects off of the sample, it is
converted into an electrical signal by the detector and analyzed by the
computer. Del Mar Photonics is looking for international distributors for
RAVEN - AOTF IR spectrometer for plastic identification and for variety of
scientific and industrial collaborations to explore futher commercial potential
of AOTF technology.

AOTF spectrometer to measure lactose, fat and proteins in milk

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.

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.

Training Workshops
Come to San Diego next summer! Attend one of our training workshops in San Diego, California
during summer 2011
Del Mar Photonics has presented training workshops for
customers and potential customers in the past 3 years.
Our workshops cover scientific basics, technical details and provide
generous time for hands-on training.
Each workshop is a three-day seminar conducted by professional lecturer from 10am to 4pm. It includes lunch, as
well as a training materials. We have also reserved two days for Q&A sessions,
one-on-one system integration discussions, social networking, and San Diego sightseeing.
Del
Mar Photonics offers new
Trestles fs/CW laser system which can be easily
switched from femtosecond mode to CW and back. Having both modes of operation in one system dramatically increase a
number of applications that the laser can be used for, and makes it an ideal
tool for scientific lab involved in multiple research projects.
Kaelyn Leake is a PhD student in Electrical Engineering. She graduated from
Sweet Briar College with a B.S. in Engineering Sciences and Physics. Her
research interests include development of nanoscale optofluidic devices and
their applications. Kaelyn is the recipient of a first-year QB3 Fellowship.
In this video Kaelyn talks about her experimental research in nanoscale
optofluidics to be done with Trestles LH laser.
Frequency-stabilized CW
single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed
in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong
Kong.
DYE-SF-077 features exceptionally narrow generation line width, which
amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation
line width of commercial lasers. Prior to this model, the narrowest line-width
of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to
note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an
acousto-optical modulator, which, as a rule, complicates the design and
introduces additional losses. A specially designed ultra-fast PZT is used for
efficient suppression of radiation frequency fluctuations in a broad frequency
range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules,
Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution
spectroscopy
Del Mar Photonics continuously expands its components
portfolio.
Solar
Prisms for Concentrating Photovoltaic Systems (CPV) Solar cells made of compound semiconductors such
as gallium arsenide are very expensive. Usually very small cells are
installed and various means such as mirrors, lenses, prisms, etc..are used
to concentrate sunlight on the cells. Concentration photovoltaic technology
(CPV) uses the solar radiation with an efficiency of 40%, double that of
conventional solar cells
Del Mar Photonics design custom Concentrating Photovoltaic Systems (CPV) and
supply variety of the optical components for CPV such as
