Thorlabs, Inc. Polarizing Beamsplitter Cubes

At Thorlabs, we constantly reinforce our desire to serve at the pleasure of our customers. From this comes our desire to be connected to our industry in a way that far exceeds what would typically be expected of a vendor. Thorlabs lives this core principle by seeking to enhance, at every turn, the productivity of our customers. We have developed a culture that constantly seeks your input; many of you have experienced this first hand, as a large portion of our product offerings are customer inspired. Others may note that a website feature exists because you let us know that it would make you more productive. A direct outcome of this customer focus is our utmost respect for your time. This drives us to question everything we do. It informs our product design, shapes our approach to manufacturing, and provides clarity for our customer service department. We constantly ask ourselves how we can make the entire process of finding, understanding, purchasing, and using a product more efficient. By saving you time, we enhance your productivity, which allows us all to foster the continued forward movement of photonics. Thorlabs offers a wide range of optical beamsplitters. Our plate beamsplitters have a coated front surface that determines the beam splitting ratio while the back surface is wedged and AR coated in order to minimize ghosting and interference effects. Pellicle beamsplitters provide excellent wavefront transmission properties while eliminating beam offset and ghosting. Our cube beamsplitters are available in polarizing or non-polarizing models. The pellicle and cube beamsplitters can be purchased premounted in cubes that are compatible with our lens tube and cage systems. Dichroic beamsplitters exhibit beamsplitting properties that are wavelength dependent. They are useful for combining / splitting laser beams of different color.
