65-146 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 486nm
The 65-146 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 25 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which is a testament to its high-quality construction and performance.
The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it, while blocking other wavelengths. In this case, the 65-146 Filter is designed to allow wavelengths around 486nm to pass through, making it ideal for applications that require precise wavelength selection.
The filter's physical data includes a cut-on wavelength of 481nm and a cut-off wavelength of 491nm, with a center wavelength (CWL) of 486nm. This means that it starts allowing wavelengths from 481nm and stops at 491nm, with the highest transmission at 486nm.
The 65-146 Filter is hard coated on both the front and back, with the front coating being EDM 65-085 and the back coating also being EDM 65-085. This coating not only enhances the filter's performance but also provides protection against environmental factors, ensuring longevity and reliability.
The filter's shape is that of a thin lens, making it suitable for a wide range of optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status.
