Since 1986, LASER COMPONENTS has been manufacturing hard dielectric coatings in Germany. The production facility is continuously upgraded with new technologies to implement customer requirements as quickly as possible and in the highest quality. Three different coating technologies are offered: depending on product requirements or quantity, the production manager selects the appropriate technology. Both small and large quantities are manufactured at surprisingly affordable prices.

The compound microscope is a useful tool for magnifying objects up to as much as 1000 times their normal size. Using the microscope takes lots of practice. Follow the procedures below both to get the best results and to avoid damaging the equipment.

With LASER COMPONENTS' cavity ring down (CRD) measurement station, reflectivity values of 99.95% and higher can be determined. Customers can therefore be sure that the optics ordered also meet the desired specifications, even for custom-made individual pieces without performing an incoming goods inspection.

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. A common exercise to demonstrate depth of focus involves laying three different colored threads one on top of the other. As the observer focuses down, first the top thread comes into focus, then the middle one, and finally the bottom one. On higer power objectives one may go out of focus as another comes into focus.

The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

When drawing what you see under the microscope, follow the format shown below. It is important to include a figure label and a subject title above the image. The species name (and common name if there is one) and the magnification at which you were viewing the object should be written below the image. All relevant parts of the drawing should be labelled on the right side of the image using straight lines. Lines should not cross. Drawings should be done in pencil, while labels should be in pen or typed. Remember that total magnification is determined by multiplying the ocular x objective.

Dielectric coatings are one of our core competencies at LASER COMPONENTS. We primarily deposit customer-specific optical coatings onto almost any substrates. E-beam technology, also referred to as physical vapor deposition (PVD), ion-assisted deposition (IAD), and ion beam sputtering (IBS) are the coating processes currently available.

But it's not just the machinery that's being upgraded - investment is also made in metrology to guarantee the consistently high quality of our products to you.
