87-249 50 mm Dia. Hard Coated Dual-Band Fluorescence Bandpass Filter; t=2 mm 512/630nm

The 87-249 is a high-quality Dual-Band Fluorescence Bandpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 2 mm, is designed for use in a variety of applications that require precise wavelength selection.

The filter is specifically designed to transmit light at two distinct wavelengths, 512 nm and 630 nm, while blocking unwanted light from other wavelengths. This is achieved through the use of a specialized coating, denoted as 'edm 87-233' on both the front and back surfaces of the filter. This coating not only enhances the filter's performance but also provides a high level of durability, ensuring the filter maintains its properties even under demanding conditions.

The physical data of the filter is equally impressive. With a cut-on wavelength of 500.5 nm and a cut-off wavelength of 523.5 nm, the filter is designed to transmit light in the narrow range around the central wavelength of 512 nm. This makes it ideal for use in fluorescence microscopy and other applications where precise wavelength selection is crucial.

The filter is designed in a Thin Lens shape, which not only adds to its functionality but also makes it compatible with a wide range of optical systems.
