84-798 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 650nm

The 84-798 is a Bandpass Filter, specifically designed by Edmund Optics with a 50 mm diameter and a thickness of 3.5 mm. This filter is engineered to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it an essential component in various optical systems.

The 84-798 filter is designed to operate at a central wavelength (CWL) of 650nm, with a cut-on wavelength of 625nm and a cut-off wavelength of 675nm. This specificity in wavelength range makes it ideal for applications that require precise light filtering, such as fluorescence microscopy, spectroscopy, and optical telecommunications.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear, a crucial factor for components that are frequently exposed to handling or environmental stressors.

The 84-798 filter is designed in a Thin Lens shape, which is a standard format in optical design, ensuring compatibility with various optical systems and components. This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
