87-762 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 510nm

The 87-762 is a Bandpass Filter with a diameter of 50 mm and a thickness of 2 mm, designed for use in fluorescence applications. This filter, sourced from Edmund Optics, is a crucial component in optical systems that require specific wavelength selection.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light from other wavelengths. The 87-762 is designed to pass light at a central wavelength (CWL) of 510nm, with a bandwidth of 20nm. This makes it ideal for applications that require the selection of light in the green spectrum.

The filter's geometry is defined by its diameter and thickness. With a diameter of 50 mm, it is suitable for use in systems with a moderate aperture. The thickness of 2 mm ensures durability and rigidity, making it suitable for use in a variety of optical systems.

The 87-762 features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also helps to reduce surface reflections, improving the overall efficiency of the optical system.

The physical data of the filter includes a cut-on wavelength of 500nm and a cut-off wavelength of 520nm. This means that the filter begins to transmit light at 500nm and stops transmitting at 520nm. This wavelength range is critical in determining the filter's performance in a given application.
