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.

 

 

 



Partial reflectors



PR 308 nm / 0°
Partial reflector or output coupler

Xe+Cl laser

Transmission of quarterwave stacks is depicted.
Virtually any reflectivity between 0.2% and 99.5% is possible.

Prices of "Standard Components".
Standard values of partial reflectors (output couplers, beam splitters and beam samplers) see tab. "Partial Reflectors".

For variable Components see Gradient output coupler or page 7.4 of our printed "Variable Components“ catalog
BS 308 nm / 45°
Beamsplitter

50% 308 nm, 45°
for random polarized light

Phase change and angular dependence of reflectivity are depicted in de following diagrams.
BS 308 nm / 45°
Beamsplitter

Phase change of the reflected and the transmitted beam. Beam splitter and Partial reflectors do not change the phase, if a quarter wave stack is used at its center wavelength. Phase of the transmitted beam is additional influenced by the thickness of the substrate.

Reflectivity vs.
angle of incidence


Beamsplitter has nearly constant 50% for random polarization up to AOI 75°.
