LASEROPTIK started an "open door" day on September 3.,2009. A lot of visitors came in to congratulate, celebrate and inform themselves about the capabilities of our production. A photo gallery of LO OPEN can be seen here or at menu item "About us > 25th anniversary".A short article (in german) describes the day and the celebrations at the "Laserhof" in Garbsen.

Standard Materials
LASEROPTIK stocks substrates for coatings in the wavelength range from 120 nm to 50 µm.
Only the highest grade materials are used in the fabrication of the components, which are listed in our catalogs.
Most orders of our customers can be met with three standard materials:
N-BK7, UV-FS and IR-FS. A wide selection of sizes for a quick delivery service is listed. With "Laseroptik EXPRESS" you can choose overnight delivery to suit your needs in 24 hours.
The transmission traces of special glasses and IR-materials are also shown.
LASEROPTIK is able to quote custom optics with these materials according to your individual wishes.
A brief characterization of the substrate materials and the refractive indices at common laser lines are given with the transmission diagrams.
A transmission overview with samples of nearly all substrate materials, usable for laser coatings, is depicted on top of this menue.
