35-883 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 290nm

The 35-883 is a 25 mm diameter Bandpass Filter, specifically designed for use in the ultraviolet (UV) spectrum with a center wavelength (CWL) of 290nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid web link provided for easy access to additional information.

The Bandpass Filter is a type of optical filter that allows light to pass within a specific range of wavelengths while blocking out other wavelengths. In this case, the 35-883 filter is designed to pass wavelengths close to 290nm, making it ideal for applications that require precise UV light filtration.

The filter features a hard coating on both the front and back surfaces, denoted as 'edm 35-876'. This coating enhances the durability and longevity of the filter, providing robust protection against scratches and other potential damage.

The geometric specifications of the filter include a diameter of 25mm and a thickness of 3.5mm. The 'cut on' wavelength is 285nm, and the 'cut off' wavelength is 295nm. These parameters further refine the filter's performance, ensuring optimal light filtration within the specified wavelength range.

The filter's shape is described as 'Thin Lens', indicating its potential use in lens systems. This versatile filter is a valuable addition to any optical setup requiring precise UV light control.
