34-979 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 330nm
The 34-979 is a 25 mm diameter Bandpass Filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications requiring a narrow passband, with a central wavelength of 330nm. The filter features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear.
The filter's geometry is defined by a 25mm diameter and a thickness of 3.5mm, making it suitable for a wide range of optical systems. The cut-on wavelength is 325nm, and the cut-off wavelength is 335nm, ensuring a tight 10nm bandpass. The CWL (Center Wavelength) of the filter is 330nm, providing a precise wavelength for various optical applications.
The coating on the filter is EDM 34-975, a proprietary coating developed by Edmund Optics for enhanced performance and durability. The filter's shape is that of a thin lens, ensuring minimal distortion and optimal light transmission.
The 34-979 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/p/330nm-cwl-25mm-dia-hard-coated-od-4-10nm-bandpass-filter/33105/.
