67-028 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 482.5nm
The 67-028 is a 25 mm diameter Bandpass Filter, specifically designed for fluorescence applications with a central wavelength of 482.5nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their website.
The filter is made from UVFS MAL-1965 material, a common choice for optical applications due to its excellent properties. It has a circular base shape, with a thickness of 2mm, providing durability and stability. The geometry of the filter is designed in a Thin Lens shape, which is often used in optical systems to minimize aberrations and distortions.
The 67-028 filter has a cut-on wavelength of 464.5nm and a cut-off wavelength of 500.5nm. This means it allows light within this specific range to pass through, while blocking other wavelengths. The Central Wavelength (CWL) is 482.5nm, indicating the peak transmission wavelength. This is particularly useful in fluorescence applications, where specific wavelengths need to be isolated.
The filter is hard coated with EDM 67-014 on both the front and back surfaces. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and maintaining its performance over time.
