Customer Service

LOOP is the name of our LASEROPTIK Online Portal. LOOP gives you online access to a selection of more than 1,200 coatings and 390 standard substrates out of our database stock with over 28,000 different coating designs and 13,000 own substrates.

We show exemplary coatings for each main and subtype and for the most common laser wavelengths.

If you do not find exactly what you are looking for, take the best matching article and specify your additional needs. We offer you an optimized coating or substrate.

We have delivered in more than 60 different countries on 6 continents. We do not have distributors, you can contact us directly. This saves time and extra costs.

To avoid degradation of optics, it is best to store them in a dry, dust-free and clean environment. The humidity should be between 20 and 50%, with a room temperature of around 23 °C that is as constant as possible.

The storage location or the used packaging should not outgas, especially water and hydrocarbons can lower the performance of optics. Moist-sensitive optics should be stored together with desiccant. For particularly sensitive applications, e.g. in the UV range, nitrogen-purged packaging may be necessary.

LASEROPTIK also uses its own boxes and membrane cans for safe shipping. Of course, these are also perfect for the storage of optics.

We recommend cleaning coated optics with clean air only.

If the surface is very dirty you can use lens cleaning tissue moistened with solvents like isopropanol or ethanol. Clean the coated surface with uniform circular movements and low pressure. Coated optics produced by IAD, MS and IBS can normally resist some more pressure.

For more detailed information see the chapter https://www.laseroptik.com/en/customer-service/cleaning-of-substrates.

In most cases, dirt, water and hydrocarbons from the environment have deposited on the surface, which can increase absorption and scattering. In this case, you can try to remove this carefully, preferably contactless by blowing off with pure air or with suitable cleaning tissues and liquids.

If the beam spot has already burned in (Laser Induced Contamination – LIC), cleaning is usually no longer possible. It may still be possible to use the optics by shifting the position of the beam spot on the surface.

Burned beam spots are usually an indication that in the beam path the wrong materials are being used for holders, sealing or the chamber itself. Or the environment of the optics is not clean enough and may need to be purged during operation.

If you already see defects on the optics (chipped layers, cracks), the optics are defective and need to be replaced. Depending on the type of damage, it may be possible to identify the causes and find a more suitable combination of substrate and coating.

If the substrate is directly affected, for example if there is a defect in the glass volume or if discoloration is visible here (color centers, fluorescence), the polishing and material of the substrate should be checked.

If the optics look fine, the following should be controlled:

Has the optical path changed, are all holders fixed?

Are there strong temperature fluctuations on the optics?

Is the laser stable?

There are other reasons why optical properties can change. Contact LASEROPTIK, we will be happy to help you.
