The 559-34 EX is a mounted excitation fluorescence bandpass filter, designed and manufactured by Iridian Spectral Technologies. This filter, with a catalog number of 559-34 EX, is available for purchase directly from the vendor's website, as indicated by its 'Valid - in stock' status.
The filter is of the bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. This particular filter has a central wavelength (CWL) of 559 nm, a cut-on wavelength of 542 nm, and a cut-off wavelength of 576 nm.
The filter is circular in shape, with a diameter of 25 mm and a thickness of 3 mm. It is made from a material identified as 'uvfs mal- 1965'. The front and back of the filter are coated with 'iri 559-34-ex', suggesting a uniform coating on both sides.
The filter's geometry is described as a 'Thin Lens', indicating its potential use in optical systems where minimal distortion and high transmittance are required. This filter is an excellent choice for applications that require precise wavelength selection and high-quality optical performance.
