ZET642NF C 25 mm Dia. Sputter Hard Coated; Laser Notch Filter

The ZET642NF is a notch filter developed by Chroma, a leading vendor in the optical industry. This filter is specifically designed for use with 642 nm lasers and features a circular base shape with a diameter of 25 mm and a thickness of 1 mm. The filter is made from UVFS MAL-1965 material, ensuring high-quality performance and durability.

The ZET642NF filter is part of Chroma's extensive catalog of optical elements and is available for purchase directly from their website. The product link provided in the item data indicates that the filter is currently in stock, ensuring quick and efficient delivery.

The filter's physical data includes a center wavelength (CWL) of 642 nm, which is the specific wavelength of light that the filter is designed to block. This makes it ideal for use in applications where precise wavelength control is required.

The ZET642NF filter is coated on both the front and back sides with Chroma's ZET642NF coating. This coating is applied using a sputter hard coating process, which enhances the filter's durability and resistance to wear and tear.

The filter's shape is described as a thin lens, which refers to its relatively thin profile compared to other optical elements. This makes it a versatile choice for a wide range of applications, as it can be easily integrated into existing optical systems.
