Attention! You can customise this product to your needs.
Wavelength separator has been known by many names invoked by different applications: dichroic mirror, beam combiner, harmonic beamsplitter, etc. This product is used to separate (or combine) spectral regions in space by exploiting dielectric thin film design. Typical applications for wavelength separator are filtering fundamental wavelength remains from second harmonic, or letting the pump wavelength pass into the resonator through the back mirror. Catalog items are designed for most common laser wavelengths, but Altechna also offers custom design wavelength separators in terms of wavelength, size and performance.
