Customer testimonial:
Last year your company provided two custom Pellin Broca prisms for our
research project. These optical components are performing very well.
We now need a third Pellin Broca prism. This needed component must be of
similar size to those delivered last year with a 30 mm x 30 mm
aperture. It should also be made of UV Grade Fused Silica. The optical
surfaces should again be lambda / 10 at the HeNe wavelength and have a Mil
Spec Scratch/Dig of 20/10.
The only significant difference from the fused silica Pellin Broca prism
your company supplied last year, is the effective wedge angle of the
dispersing prism in the Pellin Broca. Prisms delivered last years
have non-standard 45 degrees for their effective wedge angle. We now need
a prism with the standard effective wedge angle of the dispersing prism
which is 60 degrees for a Pellin Broca. The drawing below of a standard
Pellin Broca prism is from Wikipedia.
The prism width into the plane of the drawing must be 30 mm. The distance
A-B must be 45 mm to yield a 30.5 mm x 30 mm aperture.
Original inquiry:
I need a large (~40mm) custom CaF2 or MgF2 dispersing prism in a Pellin
Broca configuration.

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
solar prisms shown in the picture.

Axicon Lens
Axicon lens also known as conical lens or rotationally symmetric prism is
widely used in different scientific research and application. Axicon can be
used to convert a parallel laser beam into a ring, to create a non
diffractive Bessel beam or to focus a parallel beam into long focus depth.
Del Mar Photonics supplies axicons with cone angles range from 130° to
179.5° for use with virtually any laser radiation. We manufacture and supply
axicons made from BK7 glass, fused silica and other materials.

Rutile (TiO2) coupling
prisms
Del Mar Photonics offers optical elements made of high quality synthetically
grown Rutile Titanium Dioxide crystals. Rutile’s strong birefringency, wide
transmission range and good mechanical properties make it suitable for
fabrication of polarizing cubes, prisms and optical isolators. Boules having
high optical transmission and homogeneity are grown by proprietary method.
Typical boules have 10 - 15 mm in dia. and up to 25 mm length. Optical
elements sizes - from 2 x 2 x 1 mm to 12.7 x 12.7 x 12.7 mm. Laser grade
polish quality is available for finished elements. So far we the largest
elements that we manufactured are 12 x15 x 5 mm, in which optical axis is
parallel to 15 mm edge, 5 mm is along beam path, 12 x 15 mm faces polished
20/10 S/D, one wave flatness, parallelism < 3 arc.min. (better specs.

Thyratrons are used in
such devices as radars with different power levels, high-power pulsed
technical, electrophysical, medical devices and lasers. Sophisticated
design and high quality ceramic-metal envelope determines long lifetime
and very accurate and reliable operation of hydrogen thyratrons under wide range of environmental
conditions.
Applications:
- radars
- pulsed lasers power supplies
- medical apparatus
- electrophysical instrumentation
Triggered Three-Electrode Spark Gap Switches are ceramic-metal sealed off gas
discharge trigatron-type devices with a co-axial trigger electrode. These Gas
Discharge Tubes contain no mercury and, due to an advanced design, feature high
reliability and a long lifetime being operating under wide range of
environmental conditions.
Applications:
- pulsed installation for processing materials
- installations with plasma focus
- pulse power supplies for lasers and other pulse equipment
- medical apparatus such as lithotriptors and defibrillators
- processing systems for petroleum wells |

Trigger Transformers
Del Mar Photonics supply
trigger transformers for triggered spark gaps and
other applications.
Contact us to today to discuss your application or requesta quote.
Trigger Transformers are used to provide a fast high voltage pulse up to
30kV/µs and more. This high voltage pulse is applied to the trigger
electrode to initiate switching action in the
three-electrode
spark gaps. Either positive or negative pulses can be obtained from all
of the transformers. |
