65-152 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 510nm

The 65-152 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 510nm, making it suitable 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 65-091'. This coating enhances the filter's durability, making it resistant to wear and tear, a crucial factor for components subjected to frequent handling or those used in harsh environments.

The filter's geometry is defined by a diameter of 25 mm and a thickness of 3.5 mm. This thickness allows for efficient light transmission while maintaining the structural integrity of the filter. The 't' in the item name refers to this thickness.

The filter's physical data includes a cut-on wavelength of 505nm and a cut-off wavelength of 515nm. These values represent the boundaries within which the filter allows light to pass, effectively blocking light outside this range. The central wavelength (CWL) of the filter is 510nm, indicating the wavelength at which the filter's transmission is maximum.

The filter's shape is described as 'Thin Lens', suggesting that it may have some light-bending properties, although this is not explicitly stated in the provided data.
