84-789 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 800nm

The 84-789 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 ensures high-quality performance and durability.

The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it. In this case, the 84-789 Filter is designed to allow wavelengths around 800nm to pass through, with a Cut-On wavelength of 775nm and a Cut-Off wavelength of 825nm. This specificity in wavelength selection makes it an ideal component for various optical applications that require precise wavelength control.

The filter features hard coating on both the front and back, enhancing its durability and resistance to wear and tear. The coating type is EDM 84-777, which is a high-performance coating known for its excellent optical properties.

The 84-789 Filter is designed in a Thin Lens shape, which is a type of lens that is characterized by a short focal length and a small diameter. This shape allows for efficient light transmission and minimal optical aberrations, making it suitable for a wide range of optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information and specifications, users are encouraged to visit the provided weblink.
