64-240 12.5 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 355nm

The 64-240 is a high-performance laser line bandpass filter, boasting a 12.5 mm diameter and a thickness of 2mm. This filter is designed to operate at a central wavelength of 355nm, making it ideal for applications that require precise wavelength selection in the ultraviolet range.

The filter is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures high-fidelity light transmission while minimizing unwanted background noise.

The 64-240 features a proprietary coating (edm 64-240) on both the front and back surfaces. This coating is specifically designed to enhance the filter's performance, providing high transmission and excellent blocking characteristics. It ensures a high level of contrast and image quality, making it suitable for demanding applications.

The filter's geometry is defined by its circular shape and thin lens design. This configuration allows for easy integration into various optical systems, providing a compact and efficient solution. The filter's dimensions make it compatible with many standard optical components, facilitating its use in a wide range of applications.

In terms of physical data, the filter's cut-on wavelength (cwl) is 355nm. This parameter is crucial in determining the filter's effectiveness in blocking unwanted wavelengths. The 64-240's cwl ensures that it effectively transmits light at the desired wavelength while efficiently blocking adjacent wavelengths.
