65-156 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 535nm

The 65-156 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 535nm, 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, identified as 'edm 65-095'. This coating enhances the filter's durability, making it resistant to wear and tear, a crucial factor for components subjected to frequent handling or rigorous use.

The filter's geometry is defined by a diameter of 25 mm and a thickness of 3.5 mm. This thickness ensures the filter's structural integrity while minimizing optical distortions. The filter's base shape is circular, a common and versatile shape in optical systems due to its ease of alignment and integration.

The filter's physical data includes a cut-on wavelength of 530nm and a cut-off wavelength of 540nm. This 10nm bandpass, located at the filter's central wavelength, allows for the efficient transmission of light within this narrow range while effectively blocking unwanted wavelengths.

The filter's Material ID is UVFS MAL-1965. This identifier is crucial for tracking and managing inventory, as well as for understanding the filter's material properties when designing optical systems.
