NF533-17 Dia. 25 mm Notch Filter; CWL=533nm; FWHM=17nm

The NF533-17 is a notch filter with a circular base shape, designed and manufactured by Thorlabs. This filter is specifically designed for use in optical systems where a narrow band of wavelengths needs to be suppressed, making it ideal for applications such as fluorescence microscopy, laser spectroscopy, and optical communication systems.

The NF533-17 has a diameter of 25 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical systems. The filter is made from UVFS Mal-1965, a material known for its excellent optical properties and durability.

The notch filter has a center wavelength (CWL) of 533 nm and a full width at half maximum (FWHM) of 17 nm. This means it effectively blocks wavelengths around 533 nm while allowing other wavelengths to pass through. The front and back of the filter are coated with Thorlabs' proprietary coatings, denoted as 'tho nf533-17', which enhances its performance and durability.

The NF533-17 is available for purchase directly from Thorlabs' website, where it is listed as 'in stock', indicating quick and easy availability for your optical system needs.
