87-778 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 575nm

The 87-778 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 at a central wavelength of 575nm, 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 87-778'. 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 87-778 features a cut-on wavelength of 562.5nm and a cut-off wavelength of 587.5nm. This means it allows transmission of light within this specific range, while blocking out unwanted wavelengths. The cut-on and cut-off values are crucial in determining the filter's effectiveness in specific applications.

The filter's geometry is defined by its circular shape and a diameter of 12.5 mm. This circular shape, often referred to as a 'Thin Lens', is a common form factor for optical filters due to its ease of integration into various optical systems.
