39-314 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 343nm

The 39-314 is a Bandpass Filter, specifically designed for use in the ultraviolet (UV) spectrum, with a central wavelength (CWL) of 343nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The filter is characterized by a 25mm diameter and a thickness of 3.5mm, making it suitable for a wide range of optical applications.

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 39-314 Bandpass Filter is designed to pass light in the 343nm range, with a cut-on wavelength of 338nm and a cut-off wavelength of 348nm. This precise wavelength selection is crucial in various applications, such as fluorescence microscopy, spectroscopy, and other UV-based research or industrial processes.

The filter features a hard coating on both the front and back surfaces, denoted as 'edm 39-307'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in its performance. The filter's shape is defined as a 'Thin Lens', indicating a specific curvature designed to focus or disperse light.
