65-213 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 510nm

The 65-213 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 510nm, making it ideal for applications that require precise wavelength selection.

The filter boasts a hard coating on both the front and back surfaces, denoted as 'edm 65-091'. This coating enhances the filter's durability, making it resistant to scratches and other forms of damage, thereby ensuring longevity and reliability in its performance.

The filter's geometry is another notable feature. It has a thickness of 3.5 mm, which is crucial for applications that require specific optical path lengths. The filter's base shape is circular, a common and versatile shape in optical systems.

The physical data of the filter includes a cut-on wavelength of 505nm and a cut-off wavelength of 515nm. This 10nm bandpass is designed to transmit light within this specific range while blocking out other wavelengths. The cut-on and cut-off wavelengths are key parameters in determining the filter's performance.

The filter is made from UVFS Mal-1965 material, a detail that can be crucial for users who need to consider material compatibility in their optical systems. The filter's shape is thin lens, a design that minimizes optical aberrations and ensures high-quality performance.
