65-239 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 780nm
The 65-239 is a Bandpass Filter, specifically designed with a 50 mm diameter and a thickness of 3.5 mm. This filter, sourced from Edmund Optics, is a crucial component for applications requiring precise wavelength selection.
The filter's primary function is to allow light in a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the cut-on wavelength is 775 nm, and the cut-off wavelength is 785 nm, with the central wavelength (CWL) at 780 nm. This makes it ideal for applications that require a narrow band of light around the 780 nm wavelength.
The 65-239 filter is hard coated on both the front and back, with the coating type being EDM 65-117. This coating enhances the filter's durability and performance, making it suitable for various applications.
The filter's geometry, including its diameter and thickness, is designed to fit into most optical systems without causing significant deviations in the light path. The circular shape and thin lens design further contribute to its ease of integration into various setups.
The filter is currently in stock and available for immediate purchase through the provided weblink. With its validated status, users can trust in its availability and reliability for their optical needs.
