The spectral flatness of these beamsplitters remains consistent across their designated wavelength ranges, making them highly suitable for use with various laser wavelengths. This spectral flatness also mitigates any adverse effects caused by changes in the angle of incidence or converging/diverging beams. Each beamsplitter consists of a precision pair of high tolerance Right Angle Prisms securely bonded together, with a metallic dielectric coating applied to the hypotenuse of one of the prisms. Additionally, a broadband antireflective (BBAR) coating has been meticulously applied to every face of the beamsplitter to enhance transmission efficiency within the specified wavelength range.

Here are the factory standard specifications:

- Material options: Schott, Ohara, CDGM Optical Glass, Corning fused silica, JGS1, JGS2.
- Dimension Tolerance: +/- 0.2mm.
- Flatness: l/4 @ 632.8 nm.
- Surface Quality: 60/40 scratch and dig.
- T/R Ratio: 50/50+/- 5%, calculated as T=(Ts+Tp)/2 and R=(Rs+Rp)/2.
- Beam Deviation: Less than 3 arc minutes.
- Coatings: Broadband partial reflectance on the hypotenuse face. BBAR-coatings on all input and output faces.
