87-771 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 697nm

The 87-771 is a 50 mm diameter Bandpass Filter, specifically designed for fluorescence applications, with a center wavelength of 697nm. This filter is sourced from the reputable vendor, Edmund Optics, and is currently in stock.

The filter is made from UVFS Mal-1965 material, a common choice for optical applications due to its excellent transmission properties. It has a circular base shape, with a thickness of 2mm, providing durability and stability. The geometric specifications make it suitable for a wide range of optical systems.

The 87-771 filter features a cut-on wavelength of 659.5nm and a cut-off wavelength of 734.5nm. This specific range is crucial for fluorescence applications, as it allows for the selective transmission of light within this bandwidth. The Central Wavelength (CWL) is 697nm, which is the wavelength of maximum transmission.

The filter is hard coated on both the front and back surfaces with EDM 87-743, a coating that enhances the filter's performance and durability. The shape of the filter is thin lens, which is optimal for applications that require minimal thickness and maximum light transmission.
