65-235 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 690nm
The 65-235 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter features 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 in the 690nm wavelength range, with a Cut-On wavelength of 685nm and a Cut-Off wavelength of 695nm. This precise wavelength selection is achieved through the use of a Hard Coating on both the front and back surfaces, specifically the EDM 65-113 coating. This coating not only enhances the filter's performance but also provides durability and resistance to environmental factors.
The filter's geometry is defined by its circular shape and thin lens design. The circular shape ensures easy integration into various optical systems, while the thin lens design helps minimize optical aberrations. The filter's Material ID, UVFS MAL-1965, provides additional information for material compatibility and selection.
The filter's physical data, including the Cut-On, Cut-Off, and Central Wavelength (CWL) of 690nm, are critical for system design and performance prediction. The filter is currently in stock and available for immediate use.
