65-200 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 442nm
The 65-200 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical vendor, Edmund Optics. This filter is specifically designed for a central wavelength (CWL) of 442nm, making it ideal for applications that require narrowband transmission in this spectral region.
The filter is characterized by its hard coatedOD 4.0, which provides excellent durability and resistance to environmental factors. The thickness of the filter is 3.5 mm, which is suitable for most optical systems. The cut-on wavelength is 437nm, and the cut-off wavelength is 447nm, ensuring a tight bandpass with minimal out-of-band transmission.
The coating on both the front and back of the filter is EDM 65-078. This coating is designed to enhance the performance of the filter, providing high transmission and excellent blocking characteristics. The filter has a Thin Lens shape, which makes it compatible with a wide range of optical systems.
The 65-200 is currently in stock and available for purchase through the Edmund Optics website. The filter is part of the UVFS MAL-1965 material ID, which provides additional information about its properties and performance.
