87-767 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 615nm

The 87-767 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 transmit light within a specific range of wavelengths while blocking light outside this range. The 87-767 is designed to transmit light at a central wavelength (CWL) of 615nm, with a bandwidth of 20nm. This makes it ideal for applications that require the transmission of light in this specific range.

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 various optical systems.

The 87-767 features hard coating on both the front and back surfaces. This coating enhances the filter's durability and resistance to scratches and other forms of damage, ensuring longevity and reliability in operation.

The physical data of the filter includes the cut-on and cut-off wavelengths. The cut-on wavelength is 605nm, and the cut-off wavelength is 625nm. This means that the filter begins to transmit light at 605nm and stops transmitting at 625nm.

The filter's coating is specified as EDM 87-739 on both the front and back surfaces. This coating plays a crucial role in the filter's performance, enhancing its ability to transmit light within the specified wavelength range.
