The beamsplitters consist of a pair of precision right angle
prisms which are carefully cemented gogether to minimize the
wavefront distortion. One hypotenuse of the prism is coated with a
metal-dielectric hybrid multi-layers to form a
polarization-insensitive beamsplitter over a broadband wavelength.
To minimize the surface reflection loss, all input and output
surfaces are coated with antireflection film. Due to the metallic
film is introduced in the film stack, the non-polarizing
beamsplitter are not intended for using in high power lasers
system. The non-polarizing beamsplitter cube is ideal for use with
multiple lasers or tunable lasers. The wavelength available for
non-polarizing beam splitter is ******0nm, *******0nm, ********0nm.
And the regular size is 5X5X5, *0X*0X*0, *0X*0X*0, *5.4X*5.4X*5.4,
other dimension can be customized upon request.
