39-318 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 1450nm
The 39-318 is a 25 mm diameter Bandpass Filter, specifically designed for use at a central wavelength (CWL) of 1450nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid weblink for easy access to additional information.
The Bandpass Filter is a type of optical filter that allows light to pass within a specific range of wavelengths while blocking out other wavelengths. In this case, the 39-318 model is designed to pass light between 1445nm and 1455nm, making it ideal for applications that require a narrow band of light around the 1450nm wavelength.
The filter is constructed from UVFS Mal-1965 material, and has a thickness of 3.5mm. It features a circular shape and a thin lens design, with hard coating on both the front and back surfaces for added durability. The coating is identified as EDM 39-311, ensuring consistent performance and quality.
