86-350 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 440nm
The 86-350 is a Bandpass Filter with a diameter of 25 mm and a thickness of 2 mm, designed for use in fluorescence applications. This filter, sourced from Edmund Optics, is a crucial component in optical systems that require specific wavelength selection.
The filter's primary function is to transmit light within a specific range, while blocking other wavelengths. The 86-350 is designed to transmit light at a central wavelength (CWL) of 440nm, with a bandwidth of 40nm. This makes it ideal for applications that require the transmission of blue light.
The filter's cut-on wavelength is 417nm, and the cut-off wavelength is 463nm. This means that it begins to transmit light at 417nm and stops transmitting at 463nm, effectively filtering out wavelengths outside this range.
The 86-350 features a hard coating on both the front and back surfaces, identified as EDM 86-339. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance.
The filter's geometry is that of a thin lens, which is beneficial in applications where space is a constraint. The filter is currently in stock and available for immediate purchase from the vendor's website.
