Beamsplitter Prism is constructed by cementing two right angle prisms, Standard Cube Beamsplitters offer a range of reflection/transmission ratios. An interference coating has been applied to the hypotenuse surface of one of the prisms to provide the designated reflection/transmission ratio. Absorption loss to the coating is minimal.
Standard Cube Beamsplitters with Multi-Layer Dielectric Coating, Several Beamsplitting Ratios Available from Yutai Optics, such as T:R=50:50/70:30/80:20/60:40, wavelength for visible is ideal design for most application, other wavelength could also be available to be customized from Yutai Optics. Multiple Sizes Available 3mm-50mm are hot sale for optical instrument.Beamsplitters are Constructed by cementing two right angle prisms together. Standard Cube Beamsplitters offer a range of reflection/transmission ratios. An interference coating has been applied to the hypotenuse surface of one of the prisms to provide the designated reflection/transmission ratio. Absorption loss to the coating is minimal. Polarizing Cube Beamsplitters (PBS) & Non-Polarizing Cube Beamsplitters (NPBS) are also acceptable to be customized from Yutai Optics. For Polarizing Cube Beamsplitters, we can achieve Extinction Ratio no more than 500:1 by now. We are trying to improve our coating skill.
BK7 Optical Glass Beamsplitters
BK7(K9) is one of the most commonly used optical glasses and is widely used in the manufacture of spectroscopic prisms (PBS/NPBS) due to its excellent cost performance, wide band transmittance and good processability.
