Helium Neon Laserprice

The LASOS® Helium Neon lasertubes and modules have a robust mechanical design, excellent beam quality and long service life of up to 30,000 hours. Standard and customized models are available in a large variety in the spectral range red, green and yellow with output powers between 0.5 and 20 mW. Options are single mode or multimode, randomly or linear polarized and Brewster window tubes for educational and scientific purposes.

All our laser models can be provided with adequate OEM and laboratory power supplies, meeting the European and American standard with the availability of approvals and certificates CDRH, IEC, CSA, CE, TÜV, UL.

We take customer service seriously. In close cooperation with the sales team all customer concerns are handled with high priority. Wether it is a request, order, repair or complaint LASOS is dedicated to provide continous information on the status and to fulfil the service in a timely manner.

Helium-neonlaserwavelength

Tube supports exact two orthogonally polarized longitudinal modes. Required for special methods of frequency stabilization.

Sudden changes of the polarization of different modes espacially in short tubes. Particularly disturbing when HeNe laser tubes are used in frequency stabilized operation. Can be eliminated by special selection process.

Helium--neonlaseruses

The Helium Neon lasers are designed for multipurpose applications such as confocal laser scanning microscopy, spectroscopy, digital imaging, metrology, industrial measurement, positioning, alignment, aiming, testing, code scanning, medical, basic research, education or entertainment.

Unwanted emission besides the nominal wavelength value, often disturbing in spectroscopy and interferometry. Can be suppressed by special mirror technology.

Frequency split of He-Ne laser modes in the presence of a strong magnetic field (> 200 G). Can be used for obtaining extremely high frequency stability. LASOS® has been successful in developing tubes with specific split frequencies for defi ned magnetic fields.

This document describes the main parts and functions of a microscope. It identifies the arm, base, eyepiece, body tube, revolving nosepiece, stage, fine and coarse adjustment knobs, stage clips, iris diaphragm, mirror/light source, objective lenses, aperture, and condenser. It explains that the objective lenses are used to magnify specimens and that total magnification is calculated by multiplying the eyepiece and objective powers. Proper microscope use, handling, and storage are also outlined.Read less
