Beam Expander Enquiry
  DiOptika laser beam expander optic sets provide a versatile high quality OEM beam expander solution with a large 50mm diameter output aperture and compact optical length down to 97mm.They utilise a three element design corrected for spherical abberation with a design performance of lambda/4 which exceeds the performance of 2 element systems. Expansion ratios are 10X , 15X and 20X which can be changed by simply changing the first small lenses with one for a different expansion ratio.

Laser Beam-Expander Theory

Laser beam expanders are designed to either decrease the laser's beam spot size at large distances or produce a larger diameter         
collimated laser beam. The main types of beam expanders: Keplerian and Galilean. In its simplest form, the Galilean type consists of a
positive and a negative focal length lens whereas the Keplerian type consists of two positive focal length lenses. Both designs provide 
a certain angular magnification, called the Expander Power. The beam diameter is first increased in size by this power and then the 
beam divergence is reduced by the same power. This combination yields a beam that is not only larger, but one that is also highly
collimated. The result is a smaller beam at a large distance when compared to the laser alone.  See the below equation:

BL = ß + ØL (0.3048)
BL = Beam Diameter (mm) at distance L
ß = Increase in Beam Diameter
  = Beam Diameter (mm) x Expander Power
Ø = Decrease in Beam Divergence
  = Beam Divergence (mrad) Expander Power
L = distance (ft.)



            This equation is an approximation for the collimated output beam size at a given distance.

            In addition, an expanded beam can yield smaller spot sizes when used in combination with additional focusing optics. This is very useful 
in focusing optimization. however, many applications simply require a larger continuous beam. The beam expander power (MP) is equal 
to the ratio of the effective focal length (EFL) of the objective lens to the effective focal length of the entrance optic. The physical separation
between the objective lens and entrance optic is equal to the sum of their back focal lengths (BFL).

            DiOptika’s  beam expanders are of the Galilean type. The advantages of the Galilean design over the Keplerian is that it contains no internal
focal point therefore reducing the length.  In addition to improving beam collimation, DiOptika’s beam expanders can also be used to focus
laser beams.
