65-208 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 488nm
The 65-208 is a Bandpass Filter, specifically designed for use in optical systems that require narrowband transmission at 488nm. This filter, sourced from Edmund Optics, boasts a 50mm diameter and a thickness of 3.5mm, making it suitable for a wide range of applications.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It features hard coating on both the front and back surfaces, denoted as EDM 65-086, which enhances its durability and resistance to wear and tear.
The 65-208 has a Cut-on wavelength of 483nm and a Cut-off wavelength of 493nm, with a Central Wavelength (CWL) of 488nm. This means it allows light within this narrow bandwidth to pass through while blocking out other wavelengths, making it ideal for applications that require high spectral purity.
The filter's geometry, with a diameter of 50mm and a thickness of 3.5mm, ensures it can be easily integrated into most optical systems. Its Thin Lens shape further enhances its compatibility with various optical designs.
The filter's current status is 'In Stock', according to the vendor's website, making it readily available for immediate use. For more information, users can visit the provided weblink.
