NF488-15 Dia. 25 mm Notch Filter; CWL=488nm; FWHM=15nm

The NF488-15 is a notch filter with a circular base shape, designed and manufactured by Thorlabs. This filter is specifically designed for use with a center wavelength (CWL) of 488nm, making it ideal for applications that require precise filtering within this wavelength range.

The NF488-15 boasts a full width at half maximum (FWHM) of 15nm, ensuring a high level of specificity in the wavelengths it allows to pass through. This makes it an excellent choice for applications that require narrowband filtering, such as fluorescence microscopy or laser spectroscopy.

The filter has a diameter of 25mm and a thickness of 3.5mm, making it compatible with a wide range of optical systems. It features a thin lens shape, which helps to minimize optical aberrations and ensures optimal performance.

The NF488-15 is coated with a specialized coating on both the front and back surfaces. This coating, known as 'tho nf488-15', is designed to enhance the filter's performance and durability. It provides excellent transmission and blocking characteristics, as well as resistance to environmental factors such as moisture and dust.

This filter is currently in stock and available for purchase through the Thorlabs website. For more information, including detailed specifications and pricing, please visit the product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=NF488-15.
