34-981 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 313nm
The 34-981 is a Bandpass Filter, specifically designed for use in the ultraviolet (UV) spectrum, with a central wavelength (CWL) of 313nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website. The filter is characterized by a 50mm 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 the case of the 34-981, this range is 10nm, centered around the CWL of 313nm. This makes it ideal for applications that require the isolation of specific UV light sources.
The filter's physical data includes a cut-on wavelength of 308nm and a cut-off wavelength of 318nm. This means that it begins to transmit light at 308nm and stops transmitting at 318nm, effectively filtering out any wavelengths outside of this range.
The 34-981 is coated with a hard coating on both the front and back surfaces, identified as 'edm 34-973'. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for use in demanding environments.
The filter's shape is described as a 'Thin Lens', indicating that it has been designed to minimize optical aberrations and distortions, thereby improving the overall quality of the light passing through it.
