87-235 12.5 mm Dia. Hard Coated Dual-Band Fluorescence Bandpass Filter; t=2 mm 577/690nm
The 87-235 is a high-quality Dual-Band Fluorescence Bandpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter, with a diameter of 12.5 mm, is designed for use in a variety of applications that require precise wavelength selection.
The filter is made of UVFS Mal-1965 material, a common choice for its excellent optical properties. It is specifically designed to pass wavelengths of 577nm and 690nm, making it ideal for dual-band fluorescence applications. The cut-on wavelength is 565nm, and the cut-off wavelength is 589nm, providing a narrow and precise bandwidth for your optical system.
The filter has a thickness of 2mm, which is sufficient to provide mechanical stability while minimizing unwanted optical effects. The front and back surfaces of the filter are coated with EDM 87-235, a proprietary coating developed by Edmund Optics for enhanced performance and durability.
The filter's shape is that of a thin lens, which is suitable for a wide range of optical systems. It is currently in stock and available for immediate shipping, as indicated by its weblink status.
