65-238 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 766nm
The 65-238 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, 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. The 65-238 is designed to pass light in the 766nm range, with a Cut-On wavelength of 761nm and a Cut-Off wavelength of 771nm. This precise wavelength selection is crucial in various applications where specific light frequencies are required.
The filter features hard coating on both the front and back surfaces, identified as EDM 65-116. 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 curved surface that bends light as it passes through. This shape, combined with the filter's specific wavelength capabilities, makes the 65-238 a versatile tool for various optical applications.
According to the vendor's information, the 65-238 is currently in stock, and users can access more details through the provided weblink. This filter, like all other Edmund Optics products, is designed to meet the highest standards of optical performance and reliability.
