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.

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.

NARROW-BAND HOLOGRAPHIC FILTERS are intended for suppression of powerful beams in research and in engineering, in particular, in laser spectroscopy, and also for protection from blinding and damaging by laser radiation various photo receiver devices and operator's eyes.

Unlike conventional interference filters, which are made by vacuum evaporation techniques, holographic filters are fabricated by recording interference patterns formed between two mutually coherent laser beams. Since all layers are recorded simultaneously within a thick stack, the optical density of the notch filter is high and its spectral bandwidth can be extremely narrow. Also, since the layering profile is sinusoidal instead of square wave, holographic notch filters are free from extraneous reflection bands and provide significantly higher laser damage thresholds.



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.

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.
