4 new IBS coating machines

Double IBS capacity in 2015
LASEROPTIK enlarges from four to eight industrial IBS systems e.g. for ultrafast optics, complex filter designs or in the UV. With a custom built giant machine, LASEROPTIK also offers coatings on substrates up to 2 metres in length, made by IBS.

IBS coatings up to 2 m





LASEROPTIK now designs and produces dispersion-matched pairs of broadband chirped mirrors for even better GDD compen-sation.

 

 

 



Substrates

LASEROPTIK stocks substrates for coatings in the wavelength range from 120 nm to 50 µm. A selection of sizes for a quick delivery service is listed on the following pages. For offline reading you can also download our printed catalog version as PDF file (600 Kb): download Substrates catalog.

Nevertheless most optics supplied by LASEROPTIK are specially made at customers' requirements and drawings. So please feel free to send us your individual specifications as shown with the optics on this website.

Only the highest grade materials are used in the fabrication of the components listed on the following pages. Most orders of our customers can be met with three standard Materials: N-BK7, UV-FS and IR-FS. A brief characterization of the substrate materials and the refractive indices at the laser lines are given with the transmission diagrams.

A transmission overview with samples of nearly all substrate materials, usable for laser coatings, is depicted here. Coated surfaces can be cleaned with a soft optics tissue and pure ethanol by gently wiping them off. If the contamination is mainly dust and not strongly adhesive particles, compressed oil-free purity air can be used to blast off the surfaces.

LASEROPTIK substrates are manufactured at comparatively high quality specifications in order to keep critical optical values as scattering, absorption or beam deviation at a minimum. Besides flatness and roughness, the surface imperfections are another critical parameter.

The standard DIN ISO 10110-7 describes under section 5 the admissive amount and size of defects on a surface, e.g. 5/3 x 0,040. This size (mm) squared equals the maximum admissive area for one defect or for a larger number of smaller ones covering the same area. Please see the norm for details.

Roughly compared with the MIL 0-13830-A LASEROPTIK suggests the following interpretation:

Clear Aperture MIL-0-13830A
10 / 5 20 / 10 40 / 20 60 / 40
DIN ISO 10110-7
up to Ø 20 mm
5/3x0,025 5/3x0,040 5/3x0,063 5/3x0,10
up to Ø 50 mm
5/2x0,040 5/2x0,063 5/2x0,10 5/2x0,16
up to Ø 100 mm
5/5x0,040 5/5x0,063 5/5x0,10 5/5x0,16

In the standard DIN ISO 10110-5, the flatness is given under section 3 in fringe equivalents and is commonly transferred into values of the measuring wavelength λ (e.g. 633 nm) as shown in the following table:

3/0,1 3/0,2 3/0,5 3/1 3/2
λ/20 λ/10 λ/4 λ/2 λ
