The 87-252 is a Tri-Band Fluorescence Bandpass Filter, sourced from the reputable optical components vendor, Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 2 mm, is designed for use in a variety of applications that require precise wavelength selection.
The filter's primary function is to transmit light in three specific wavelength bands: 432nm, 517nm, and 615nm. This is achieved through a careful design process that includes cutting on at 414nm and cutting off at 450nm. The result is a filter that allows for the passage of light in the desired wavelengths while effectively blocking out unwanted light.
The 87-252 filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. The filter is coated on both the front and back with EDm 87-236, a hard coating that enhances the filter's durability and longevity.
This filter is designed in the shape of a thin lens, making it suitable for use in a wide range of optical systems. The catalog number for this item is 87-252, and it is currently in stock. For more information, including pricing and availability, please refer to the provided weblink.
