65-138 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 436nm
The 65-138 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 25 mm 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 431nm, and the Cut-Off wavelength is 441nm, with the Central Wavelength at 436nm. This makes it ideal for applications that require narrow-band light transmission around this wavelength.
The filter is coated on both sides with EDM 65-077, a hard coating that enhances its durability and resistance to wear and tear. This coating also aids in maintaining the filter's performance over time, ensuring consistent light transmission.
The filter's Thin Lens shape allows for easy integration into optical systems, while its circular geometry provides uniform light transmission across the entire surface. With a catalog number of 65-138 and a current status of being in stock, this filter is readily available for your optical needs.
