Optical Glass Bk7 K9 Beamsplitter Cube For Laser And Optical Instruments

Short Description:

Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction: A beamsplitter is an optical component used to split a beam of incident light into two parts in a laser or illumination system. Cube beamsplitters consist of a pair of precision right-angle prisms carefully cemented or optically contacted together. The hypotenuse of one of the prisms is coated with polarizing or non-polarizing beamsplitter coating and four sides of the cube are AR coated to minimize surface reflection losses. Plate beamsplitters feature a coated front surface that determines the beamsplitting ratio, while the wedged back surface is AR coated to minimize ghosting. Dichroic beamsplitters are wavelength dependent and are used to combine or split laser beams in a variety of colors. Laser beam attenuators provide high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction.

Splitter Applications

Two major examples of the usefulness of beam splitters are:
*Emission image splitters: splitting image light from a microscope and re-aligning it so one camera can detect multiple images.
*Multiple camera adapter: splitting image light from a microscope into multiple cameras so that each one handles a specific wavelength.
