67-018 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 543nm

The 67-018 is a circular Bandpass Filter with a diameter of 12.5 mm and a thickness of 2 mm, designed for use in fluorescence applications. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase on their website.

The filter is specifically designed for a central wavelength (CWL) of 543 nm, making it ideal for use in applications that require this specific wavelength. The cut-on wavelength is 529.5 nm, and the cut-off wavelength is 556.5 nm, providing a narrow bandwidth that helps to reduce unwanted noise and improve the signal-to-noise ratio.

The 67-018 filter is made from UVFS Mal-1965 material, a high-quality optical material known for its excellent transmission characteristics and durability. The filter is hard coated on both the front and back surfaces with the EDM 67-018 coating, which enhances its performance and longevity.

The filter's geometry is that of a thin lens, making it suitable for use in a wide range of optical systems. The catalog number for this item is 67-018, and it is currently in stock on the Edmund Optics website, as indicated by its weblink status.
