67-073 25 mm Dia. Fluorescence Dichroic Filter 520nm
The 67-073 25 mm Dia. Fluorescence Dichroic Filter, available from Edmund Optics, is a high-quality optical component designed for precise wavelength discrimination. This filter, with a diameter of 25 mm and a thickness of 1.05 mm, is a circular dichroic filter, specifically designed for use in fluorescence applications.
The filter's primary function is to reflect light at a specific wavelength (520nm) while transmitting light at other wavelengths. This is achieved through the use of a specialized coating, denoted as 'edm 67-057' on both the front and back surfaces of the filter. The cut-on wavelength is 520nm, indicating that the filter begins to transmit light at this wavelength, while the cut-off wavelength is 0, meaning it continues to transmit all wavelengths above 520nm.
The material used in the construction of this filter is UVFS Mal-1965, a common choice for optical filters due to its excellent optical properties. The filter's geometry is that of a thin lens, further enhancing its optical performance.
The filter's catalog number is 67-073, and it can be found on the Edmund Optics website, where it is currently in stock. The link to the product page is provided for your convenience.
