65-076 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 430nm

The 65-076 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable vendor Edmund Optics. This filter is specifically designed for use with a central wavelength of 430nm, making it ideal for applications that require precise wavelength selection within this range.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-076'. This coating enhances the filter's durability and resistance to wear, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most applications.

The 65-076 features a cut-on wavelength of 425nm and a cut-off wavelength of 435nm. This narrow passband is achieved through the use of a thin lens shape, which helps to minimize optical aberrations and maintain high transmission efficiency. The filter's physical data, including the cut-on, cut-off, and central wavelength, are all precisely controlled during manufacturing to ensure consistent performance.

This filter is available for purchase directly from the Edmund Optics website, where it is listed as being in stock. The product page also provides a catalog number (65-076) for easy reference and ordering.
