非偏振平板分束镜是欧洲进口的高性能BSNP激光镜片，采用介质膜镀膜技术，损伤阈值高达6J/cm^2,Rs和Rp的分离低于5%，非常适合非偏振光和偏振光使用。
非偏振平板分束镜与非偏振分束立方体相比，具有更高的性能。
In comparison to non-polarizing beamsplitter cubes, our plate beamsplitters feature outstanding performance. Cubes typically cause loss of at approximately 10 %, because of absorption in hybrid coatings. At the same time laser induced damage threshold scales in range of approximately 0.3 J/cm2. Non-polarizing beamsplitting plates are coated with only dielectric layers, thus damage threshold is much higher and exceeds 6 J/cm2. Separation of polarizations Rs - Rp typically is lower than 5 %. Because of this feature beamsplitters are suitable for use with unpolarized light or light of any other state of polarization. Standard items have a decent working bandwidth of several tens of nanometers, what makes them usefull for several lasers. For example 1-OS-2-0254-5-[4G45-50] beamsplitter (Rsp=50 % @ 1025 nm - 1095 nm) can be used with Yb:KGW, Yb:YAG, Nd:YAG, Yb:Glass, Nd:Glass lasers. For usage with femtosecond lasers, Altechna has designed 1-OS-2-0254-5-[4F45-50] and 1-OS-2-0254-5-[4C45-50] beamsplitters, which do not influence pulse width, as coatings are GDD compensated. Custom size configurations and non-standard wavelengths are also available.
