33-327 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 631nm
This is a 25 mm diameter Bandpass Filter, specifically designed for fluorescence applications with a central wavelength of 631nm. The filter is sourced from the reputable vendor, Edmund Optics, and is identified by the catalog number 33-327. It is currently in stock and available for immediate purchase via the provided weblink.
The filter is made from UVFS MAL-1965 material, a common choice for optical applications due to its excellent transmission characteristics and durability. It features a thickness of 2mm, providing sufficient structural integrity for most applications. The filter's geometry is circular, a standard shape for optical components due to its ease of integration into various systems.
The Bandpass Filter is designed to transmit light within a specific range of wavelengths, in this case, 631nm. The cut-on wavelength is 620.5nm, and the cut-off wavelength is 641.5nm. This means that the filter will block or attenuate light outside of this range, enhancing the signal-to-noise ratio in your optical system.
The filter is hard coated with EDM 33-326 on both the front and back surfaces. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-term performance and reliability. The filter's shape is that of a Thin Lens, which can help to focus or collimate light in your optical system.
