65-144 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 470nm

The 65-144 is a Bandpass Filter, specifically designed with a center wavelength of 470nm, sourced from the reputable vendor, Edmund Optics. This filter is circular in shape, with a diameter of 25mm and a thickness of 3.5mm, making it a robust and compact solution for various optical applications.

The filter is made from UVFS MAL-1965 material, ensuring high-quality performance and durability. It features hard coating on both the front and back, specifically EDM 65-083, which enhances its resistance to wear and tear, thereby extending its lifespan.

The 65-144 Bandpass Filter has precise cut-on and cut-off wavelengths of 465nm and 475nm, respectively, and a central wavelength of 470nm. This specificity in wavelength management makes it an ideal choice for applications requiring narrow-band light transmission.

The filter's geometry is designed in the shape of a thin lens, optimizing its light transmission capabilities. The physical data, including the cut-on, cut-off, and central wavelength, are all carefully controlled during the manufacturing process to ensure the filter's high performance and reliability.
