Del Mar Photonics featured components

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 solar prisms shown in the picture.
hexagonal light pipes, optical rods
High Concentration Photovoltaic Panel (HCPV) - request for information
Solar Glass reflectors & optics for solar power generation & solar heating
Ultrafast studies of charge carrier dynamics in nanomaterials and relevance to solar energy conversion

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.

Del Mar Photonics offers optical elements made of high quality synthetically grown Rutile Titanium Dioxide crystals. 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. available on request).

Hydrogen 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.
- 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.
- 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.


We are looking forward to hear from you and help you with your optical and crystal components requirements. Need time to think about it? Drop us a line and we'll send you beautiful Del Mar Photonics mug (or two) so you can have a tea party with your colleagues and discuss your potential needs.
