87-254 50 mm Dia. Hard Coated Tri-Band Fluorescence Bandpass Filter; t=2 mm 464/542/639nm
The 87-254 is a Tri-Band Fluorescence Bandpass Filter, sourced from the reputable optical vendor, Edmund Optics. This filter, with a 50 mm diameter and a thickness of 2 mm, is designed for use in a variety of optical systems that require precise wavelength selection.
The filter's primary function is to transmit light in three specific wavelength bands: 464nm, 542nm, and 639nm. This is achieved through a careful design that includes a cut-on wavelength of 452.5nm and a cut-off wavelength of 475.5nm. The central wavelength (CWL) of the filter is 464nm, which is the wavelength at which the filter's transmission is at its maximum.
The 87-254 filter is made from UVFS Mal-1965 material, a choice that ensures durability and high-quality performance. The filter is coated on both the front and back with EDM 87-238, a hard coating that enhances the filter's resistance to wear and tear, making it suitable for use in demanding environments.
The filter's shape is that of a thin lens, a design that minimizes optical aberrations and ensures that the transmitted light is as close to the ideal as possible. This filter is currently in stock and available for immediate use. For more information, including pricing and detailed specifications, please refer to the provided weblink.
