65-191 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 365nm
The 65-191 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 is renowned for its high-quality performance.
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 360 nm, and the Cut-Off wavelength is 370 nm, with the Central Wavelength at 365 nm. This makes it ideal for applications that require narrowband transmission in the ultraviolet region of the spectrum.
The 65-191 filter is hard coated on both the front and back sides with the EDM 65-069 coating. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance.
The filter's geometry is in the form of a Thin Lens, which is beneficial for applications that require minimal optical path differences. This feature also contributes to the filter's compact design, making it suitable for systems with limited space.
