65-202 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 455nm
The 65-202 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 50 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which ensures high-quality performance and durability.
The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking other wavelengths. In this case, the Cut-On wavelength is 450 nm, and the Cut-Off wavelength is 460 nm, with a Central Wavelength (CWL) of 455 nm. This makes it ideal for applications that require narrowband transmission in the blue-violet region of the spectrum.
The 65-202 filter features hard coating on both the front and back surfaces, identified as EDM 65-080. This coating enhances the filter's durability and resistance to environmental factors, making it suitable for use in various conditions.
The filter's shape is defined as a Thin Lens, which is a type of optical component with a thickness significantly smaller than its diameter. This shape is often used in optical systems to minimize optical aberrations and improve overall system performance.
