500FDC12 12.5 mm Dia. Bandpass Dichroic Filter 500nm

The 500FDC12 is a Dichroic Filter with a 12.5 mm diameter, designed for use in optical systems that require a bandpass filter centered at 500nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. It has a thickness of 1.1mm, providing sufficient structural integrity while maintaining minimal optical path differences.

The 500FDC12 features a dichroic coating on both the front and back surfaces, specifically the KNI 500fdc-0 coating. This coating is designed to reflect or transmit light within a specific wavelength range, in this case, between 480nm and 520nm. This makes it ideal for applications that require the selective filtering of light around the 500nm wavelength.

The filter is shaped as a thin lens, which can be beneficial in certain optical system designs. The lens shape can help to control the divergence or convergence of light, depending on the system's requirements.
