64-249 25 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 363.8nm

The 64-249 High Performance Laser Line Bandpass Filter is a circular filter with a 25 mm diameter and a thickness of 2 mm. This filter is designed to work with a central wavelength of 363.8 nm, making it suitable for applications that require precise wavelength control.

The filter is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. This material ensures that the filter provides high-performance laser line filtering, minimizing unwanted light and maximizing the transmission of the desired wavelength.

The front and back of the filter are coated with EDM 47-539, a broadband anti-reflection coating. This coating is designed to reduce surface reflections, improving the overall transmission of the filter and reducing unwanted back reflections. The coating is broadband, meaning it is effective over a wide range of wavelengths, not just the central wavelength of the filter.

The filter has a shape described as a Thin Lens, which suggests that it may have some degree of optical power. However, the specifics of this are not provided in the item data.
