86-361 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 440nm

The 86-361 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter boasts a 50 mm diameter and a thickness of 2 mm, making it a robust and versatile option for various optical setups.

The filter is designed to transmit light within a specific wavelength range, centered at 440nm, with a bandwidth of 40nm. This is facilitated by the cut-on wavelength at 417nm and the cut-off wavelength at 463nm. The Center Wavelength (CWL) of 440nm is particularly useful in fluorescence applications, where specific wavelengths are often needed to excite fluorescent materials.

The 86-361 filter 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 wear and tear, making it suitable for demanding environments.

The filter's geometry is shaped as a Thin Lens, which can be beneficial in certain optical configurations. The catalog number for this item is 86-361, and it can be found on the Edmund Optics website, where it is currently in stock.
