65-231 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 650nm
The 65-231 is a Bandpass Filter, specifically designed for use in optical systems where precise wavelength selection is required. This filter, sourced from Edmund Optics, boasts a 50 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is designed to transmit light within a specific wavelength range, while blocking light outside of this range. The cut-on wavelength is 645 nm, and the cut-off wavelength is 655 nm, with a central wavelength of 650 nm. This makes it ideal for applications where light at 650 nm needs to be isolated or emphasized.
The 65-231 filter features hard coating on both the front and back surfaces, providing enhanced durability and resistance to scratches and other forms of damage. The coating material is UVFS Mal-1965, which is specifically designed for optical applications.
The filter has a circular shape and a Thin Lens design, which helps to minimize optical aberrations and distortions. This, combined with its robust construction, makes the 65-231 an excellent choice for demanding optical applications.
