87-239 12.5 mm Dia. Hard Coated Quad-Band Fluorescence Bandpass Filter; t=2 mm 440/521/607/700nm

The 87-239 is a Quad-Band Fluorescence Bandpass Filter, sourced from the reputable optical vendor, Edmund Optics. This filter is designed with a circular shape, featuring a diameter of 12.5 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.

The filter is constructed from UVFS MAL-1965 material, a choice that enhances its performance in specific wavelength ranges. It is designed to pass wavelengths of 440nm, 521nm, 607nm, and 700nm, while effectively blocking other wavelengths. This makes it an ideal component for applications that require precise wavelength selection.

The 87-239 filter features hard coating on both the front and back surfaces, denoted as 'edm 87-239'. This coating not only enhances the durability of the filter but also reduces surface reflections, thereby improving overall transmission.

The filter's physical data includes a cut-on wavelength of 420nm and a cut-off wavelength of 460nm, with a central wavelength (CWL) of 440nm. This physical data further emphasizes the filter's capability to pass specific wavelengths while blocking others.

The filter is designed in the shape of a thin lens, allowing for easy integration into various optical systems. According to the vendor's information, this item is currently in stock, ensuring quick delivery upon order.
