65-193 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 400nm
The 65-193 is a 50 mm diameter Bandpass Filter, specifically designed for use in applications where precise wavelength selection is required. This filter, offered by Edmund Optics, boasts a center wavelength of 400nm, making it ideal for applications that operate within this spectral range.
The filter is hard coated, which enhances its durability and resistance to wear and tear, ensuring a longer lifespan and maintaining its performance over time. The OD (Outside Diameter) is 4.0, providing a substantial surface area for easy integration into optical systems.
The 65-193 features a 10nm bandpass, which is the width of the filter's passband, the range of wavelengths that it allows to pass through. This narrow bandpass ensures high spectral purity, making it suitable for applications that require precise wavelength control.
The filter has a thickness of 3.5mm, which contributes to its robustness and stability. It is designed with a cut-on wavelength of 395nm and a cut-off wavelength of 405nm, ensuring efficient blocking of unwanted wavelengths.
The coating on both the front and back of the filter is EDM 65-071, which enhances its performance and durability. The filter's shape is that of a thin lens, making it compatible with a wide range of optical systems.
