25.4mm Dia., 355nm T, 266nm R 45° Thin Harmonic Separator

Product Details Used to Separate Nd:YAG Harmonic Wavelengths Beamsplitter Coating Features >95% Transmission λ/10 Fused Silica Substrate TECHSPEC Nd:YAG Harmonic Separators are used to separate the common harmonic wavelengths of an Nd:YAG laser. A beamsplitter coating on the first surface reflects at least one wavelength and transmits another. The second surface of the beamsplitter features an anti-reflective coating to minimize the loss due to reflection. TECHSPEC Nd:YAG Harmonic Separators are available in 45° and 0° angle of incidence options. These harmonic separators are available in multiple wavelength configurations for optimal flexibility in system design. Note: The Damage Threshold values we publish for this family of products were all tested independently from one another. When using these products with more than 1 incident beam, the resulting Damage Threshold of the system will be negatively impacted.
