34-982 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 320nm

The 34-982 is a Bandpass Filter, sourced from Edmund Optics, with a diameter of 50 mm and a thickness of 3.5 mm. This filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it ideal for applications that require narrow-band light.

The filter's central wavelength (CWL) is 320nm, which is the wavelength at which the filter's transmission is maximum. The cut-on wavelength is 315nm, and the cut-off wavelength is 325nm, indicating the range of wavelengths that the filter allows to pass. The filter's material ID is UVFS MAL-1965, which can provide additional information about its properties and compatibility with other optical elements.

The 34-982 features hard coating on both the front and back surfaces, denoted as 'edm 34-974'. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-term performance and reliability. The filter's shape is thin lens, which is a common form factor for optical elements, facilitating integration into various optical systems.

According to the vendor's information, the filter is currently in stock, and more details can be found on the product's webpage. This filter's specifications make it suitable for applications that require narrow-band light at the 320nm wavelength, such as fluorescence microscopy, spectroscopy, and other scientific research fields.
