84-793 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 400nm

The 84-793 is a Bandpass Filter, sourced from Edmund Optics, with a catalog number 84-793. This filter is designed for use in optical systems that require narrowband transmission at specific wavelengths while blocking unwanted light. The filter has a circular shape with a diameter of 50 mm and a thickness of 3.5 mm, making it suitable for various optical applications.

The 84-793 filter is centered at 400nm, with a cut-on wavelength of 375nm and a cut-off wavelength of 425nm. This specificity in wavelength allows the filter to transmit light within a narrow band, enhancing the signal-to-noise ratio in the optical system. The filter is made from UVFS Mal-1965 material, which is known for its excellent optical properties and durability.

The filter is hard coated on both the front and back surfaces with EDM 84-769 coating. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The filter's shape is that of a thin lens, which minimizes optical aberrations and ensures high-quality imaging.

The 84-793 filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. This filter is a reliable choice for applications that require narrowband transmission, such as fluorescence microscopy, spectroscopy, and laser systems.
