84-077 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 377nm

The 84-077 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for fluorescence applications, featuring a center wavelength (CWL) of 377nm and a 50nm bandwidth.

The filter is made from UVFS MAL-1965 material, a high-performance optical material known for its excellent transmission characteristics in the ultraviolet and visible spectra. The filter's geometry includes a thickness of 2mm, providing robustness and durability.

The 84-077 filter is hard coated on both the front and back surfaces with EDM 84-077, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflections and increasing transmission, thereby improving the overall signal-to-noise ratio in your optical system.

The filter's cut-on wavelength is 350nm, and the cut-off wavelength is 404nm. This means that the filter will pass wavelengths between these two values while blocking wavelengths outside this range. This feature is crucial in fluorescence applications, where it is essential to isolate the fluorescence signal from the excitation light.

The 84-077 filter is available in a Thin Lens shape, making it compatible with various optical systems and configurations. According to the vendor's website, this item is currently in stock, ensuring quick delivery and minimal lead times.
