DIA32.0xT15.0mm 400-700nm Beamsplitter Disc(50:50)

P/N: NPBSD-VIS-R03201500-50

These disk type beamsplitter “cube” provide a 50:50 split ratio and to work over a broad wavelength range of 400-700nm. The entrance and exit surfaces are anti-reflection coated while the diagonal internal surface has the broadband beam splitting coating. Unlike standard beamsplitter cubes, this design offers circular block which are very friendly mountable.
