65-174 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 690nm
The 65-174 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable vendor Edmund Optics. This filter is specifically designed for use with a central wavelength of 690nm, making it suitable for a wide range of applications that require precise wavelength selection.
The filter is constructed with a thickness of 3.5 mm, providing durability and stability. It features hard coating on both the front and back surfaces, denoted as 'edm 65-113', which enhances its resistance to wear and tear, thereby extending its lifespan.
The Bandpass Filter is of the Circular type, a common shape due to its ease of use and integration into various optical systems. The 'UVFS MAL-1965' material ID further attests to its quality and performance.
The filter's physical data includes a cut-on wavelength of 685nm and a cut-off wavelength of 695nm, ensuring a tight bandpass around the central wavelength. The Cut-On Wavelength (CWL) is 690nm, indicating the wavelength at which the filter starts to transmit light.
The filter's geometry is defined by its diameter and thickness. With a diameter of 25 mm, it can be integrated into many optical systems. The 'Thin Lens' shape further enhances its compatibility with various setups.
