84-112 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 494nm
The 84-112 is a 50 mm diameter Bandpass Filter, specifically designed for Fluorescence applications, offered by Edmund Optics. This filter has a center wavelength of 494nm, making it ideal for use in systems where this wavelength needs to be isolated or enhanced. The filter is 2mm thick, providing sufficient structural integrity for most applications.
The filter is cut on at 481.5nm and cut off at 506.5nm, ensuring a narrow bandwidth that helps to reduce unwanted signals and noise. The Cut-On Wavelength (CWL) is 494nm, which is the wavelength at which the maximum transmission occurs. This precise wavelength control is crucial in many optical systems.
The 84-112 filter features hard coating on both the front and back surfaces, identified as EDM 84-080. This coating enhances the durability of the filter, making it resistant to scratches and other forms of damage, thereby increasing its longevity.
The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical system designs. The catalog number for this item is 84-112, and it can be found on the Edmund Optics website, where it is currently in stock.
