65-246 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 940nm
The 65-246 is a Bandpass Filter, specifically designed by Edmund Optics with a 50 mm diameter and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, ensuring high-quality performance and durability.
The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking out other wavelengths. In this case, the Cut-On wavelength is 935nm, and the Cut-Off wavelength is 945nm, with the Central Wavelength at 940nm. This makes it ideal for applications that require a narrow band of light around the 940nm wavelength.
The 65-246 filter features hard coating on both the front and back surfaces, denoted as EDM 65-124. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for use in various environments.
The filter's shape is defined as a Thin Lens, which is a type of optical component with a curved surface that bends light as it passes through. This shape can be beneficial in certain applications where light needs to be focused or dispersed.
The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its specifications and features, the 65-246 filter is a reliable choice for applications that require a narrow bandpass filter around the 940nm wavelength.
