NF594-23 Dia. 25 mm Notch Filter; CWL=594nm; FWHM=23nm

The NF594-23 is a notch filter with a diameter of 25 mm, designed for use in optical systems that require precise wavelength selection. This filter is manufactured by Thorlabs, a leading vendor in the field of optical components. The filter is designed with a center wavelength (CWL) of 594 nm and a full width at half maximum (FWHM) of 23 nm, making it ideal for applications that demand narrowband wavelength rejection.

The NF594-23 is made from UVFS material, specifically identified as "uvfs mal- 1965" in the item data. This material is known for its excellent optical properties, ensuring high-quality performance in a variety of applications. The filter has a thickness of 3.5 mm, which is a standard dimension for many optical components, allowing for easy integration into existing systems.

The coating on both the front and back of the filter is "tho nf594-23". This coating is specifically designed to enhance the filter's performance, providing superior wavelength rejection and transmission characteristics. The filter's shape is described as "Thin Lens", indicating that it may have lens-like properties, which could be beneficial in certain optical configurations.
