86-357 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 625nm

The 86-357 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter boasts a 25 mm diameter and a thickness of 2 mm, making it a versatile and robust option for various optical setups.

The filter is designed to transmit light within a specific wavelength range, centered at 625nm. The cut-on wavelength is 612.5nm, and the cut-off wavelength is 637.5nm, providing a narrow bandwidth that aids in reducing unwanted background noise. This feature is particularly beneficial in fluorescence applications, where specific wavelengths need to be isolated for accurate detection and measurement.

The 86-357 filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent transmission characteristics and durability. The filter is coated on both the front and back surfaces with EDM 86-346, a hard coating that enhances the filter's resistance to scratches and environmental damage, ensuring longevity and reliability in various operating conditions.

The filter's thin lens shape allows for easy integration into existing optical systems, while its circular geometry provides symmetry and simplicity in design. The filter's specifications, including its wavelength, geometry, and physical data, are all carefully controlled to ensure consistent performance across different units.
