Plate Beam Splitters are a type of Beam Splitter used in many life sciences, imaging, or laser applications, as well as in the entertainment and design industry.  Our Broadband Linear Plate Beam Splitter coatings are nearly wavelength independent across the visible spectrum. Therefore, both beams propagating from the beam splitter are virtually neutral in color. Since there is very little light loss due to absorption, the sum of the reflected and transmitted beam intensity nearly equals that of the incident beam. Broadband Linear Plate Beam Splitters are typically designed for a 45° angle of incidence, and when positioned at a 45° AOI a portion of the light striking the Plate Beam Splitter is transmitted, while another portion is reflected – therefore it is possible to produce beams of equal or varying intensity.  Many of our Plate Beam Splitters are available with the second surface coated with an anti-reflection (AR) to enhance each beam splitter’s overall efficiency and to prevent unwanted ghost reflections.
