47-615 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 450nm
The 47-615 is a Longpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This filter features a circular shape with a diameter of 25 mm and a thickness of 3 mm, designed to fit applications requiring a Thin Lens geometry.
The filter's primary function is to allow light of longer wavelengths to pass through while blocking or attenuating shorter wavelengths. In this case, it is designed to cut on at 450 nm, meaning it begins to transmit light at this wavelength and beyond. The cut off value is 0 nm, indicating that it blocks all wavelengths below 450 nm. This specific model has a peak wavelength of 588 nm.
The 47-615 is made from UVFS Mal- 1965, a material known for its optical properties. The front and back of the filter are coated with EDm 49-025, a coating that enhances the filter's performance and durability.
This filter is currently in stock and available for purchase on the Edmund Optics website. For more detailed information, you can visit the product page at https://www.edmundoptics.com/p/450nm-250mm-diameter-od-2-longpass-filter/7697/.
