87-243 25 mm Dia. Hard Coated Dual-Band Fluorescence Bandpass Filter; t=2 mm 577/690nm
The 87-243 is a high-quality Dual-Band Fluorescence Bandpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter, with a diameter of 25 mm and a thickness of 2 mm, is designed for use in applications that require precise wavelength selection and blocking of unwanted light.
The filter is specifically designed for dual-band fluorescence, with a Cut-On wavelength of 565 nm and a Cut-Off wavelength of 589 nm. The Central Wavelength (CWL) of the filter is 577 nm, which is the wavelength at which the filter has its maximum transmittance. This makes it ideal for applications that require the isolation of specific wavelengths within the fluorescence spectrum.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties and durability. The front and back surfaces of the filter are coated with EDM 87-235, a hard coating that provides enhanced protection against scratches and other forms of damage. The filter's shape is that of a Thin Lens, which helps to minimize optical aberrations and ensures optimal performance.
The 87-243 filter is currently in stock and available for immediate purchase. For more information, including detailed specifications and pricing, please visit the product webpage at https://www.edmundoptics.com/p/577690nm-25mm-dia-dual-band-filter/29623/.
