39-321 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 343nm

The 39-321 is a Bandpass Filter, specifically designed for use in the ultraviolet (UV) spectrum with a center wavelength (CWL) of 343nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry. The filter is circular in shape, with a diameter of 50mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications.

The 39-321 filter is hard coated on both sides with the coating type edm 39-307. This coating enhances the filter's durability and performance, ensuring reliable operation even under demanding conditions. The filter's bandpass characteristics are defined by its cut-on wavelength of 338nm and cut-off wavelength of 348nm. This narrow bandpass allows for precise wavelength selection, reducing unwanted noise and enhancing signal clarity.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the UV spectrum. This material ensures high transmittance at the desired wavelength, while minimizing unwanted reflections and scattering. The filter's thin lens shape further contributes to its performance, reducing optical aberrations and improving image quality.

The 39-321 filter is currently in stock and available for purchase through the Edmund Optics website. With its robust design, precise wavelength selection, and high-quality construction, this filter is an excellent choice for any application requiring a 343nm bandpass filter in the UV spectrum.
