87-794 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 775nm
The 87-794 is a Bandpass Filter, specifically designed for applications requiring a narrow passband. This filter, sourced from Edmund Optics, boasts a 25 mm diameter and a thickness of 3.5 mm, making it suitable for various optical systems.
The filter's primary function is to transmit light within a specific range of wavelengths while blocking other wavelengths. In this case, the Cut-On wavelength is 762.5 nm, and the Cut-Off wavelength is 787.5 nm, with the Central Wavelength at 775 nm. This configuration ensures that only light within this narrow band is transmitted, enhancing the signal-to-noise ratio in your optical system.
The 87-794 filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties. The front and back surfaces are coated with EDM 87-782, a hard coating that enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in your optical system.
The filter's Thin Lens shape allows for easy integration into various optical systems. It is currently in stock and available for immediate use. For more information, you can refer to the vendor's website through the provided weblink.
