87-780 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 675nm

The 87-780 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 675nm, making it suitable for applications that require precise wavelength selection within this range.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 87-780'. This coating enhances the filter's durability and resistance to wear and tear, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most applications.

The 87-780 features a Cut-On wavelength of 662.5nm and a Cut-Off wavelength of 687.5nm. This means that it allows light within the specified wavelength range to pass through while blocking out unwanted wavelengths. The Cut-On and Cut-Off wavelengths are crucial specifications for any bandpass filter, as they determine the filter's passband.

The filter's geometry is defined by its diameter and thickness. With a diameter of 12.5 mm, it can be used in a variety of optical systems. The thickness, 3.5 mm, is also a significant factor, as it can affect the filter's optical performance and the overall design of the optical system.
