65-171 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 656nm
The 65-171 is a Bandpass Filter, specifically designed for use in optical systems that require a narrow bandwidth transmission. This filter, sourced from Edmund Optics, has a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is designed to transmit light in the 656 nm range, with a cut-on wavelength of 651 nm and a cut-off wavelength of 661 nm. This specificity ensures that only the desired wavelengths are transmitted, reducing noise and improving signal clarity.
The 65-171 filter features hard coating on both the front and back surfaces, denoted as 'edm 65-110'. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance and reliability.
The filter's geometry is defined as a Thin Lens, which is a type of optical element with a curved surface that bends light as it passes through. This feature can be beneficial in certain applications where light needs to be focused or dispersed.
The filter's catalog number is 65-171, and it is currently in stock. More information and purchasing options can be found on the Edmund Optics website, with the provided weblink serving as a direct link to the product page.
