NF03-561E-25 25 mm Dia. 561nm StopLineSingle-Notch Filter by Semrock

The NF03-561E-25 is a 25 mm Dia. StopLineSingle-Notch Filter, specifically designed for use in optical systems that require precise wavelength control. This filter, manufactured by Semrock, is a notch filter, which means it is designed to transmit light in a narrow band while blocking light in other wavelengths.

The NF03-561E-25 has a center wavelength (CWL) of 561.4 nm, making it ideal for applications that require precise filtering around this wavelength. The filter is circular in shape, with a diameter of 25 mm and a thickness of 2 mm, ensuring a compact and robust design suitable for various optical setups.

The filter's coating is a crucial aspect of its performance. Both the front and back surfaces of the filter are coated with the same material, Sem NF03-561E, which is specifically designed to provide the desired optical characteristics. This coating ensures high transmission in the passband and high blocking in the stopband.

The physical data of the filter includes the CWL, which is 561.4 nm. This information is essential for designers and engineers when selecting and integrating this filter into their optical systems.

In terms of shape, the filter is designed as a thin lens, which not only contributes to its compactness but also allows for easy integration into various optical systems. The catalog number for this filter is NF03-561E-25, and it is currently in stock, according to the vendor's website.
