LL01-248-12.5 12.5 mm Dia. 248.6nm MaxLinelaser clean-up Filter by Semrock
Semrock's LL01-248-12.5 is a Bandpass Filter, specifically designed for use with 248.6nm wavelength lasers. This filter is circular in shape, with a diameter of 12.5mm and a thickness of 2mm, making it a versatile and compact option for various applications.
The filter is made from UVFS Mal-1965 material, a choice that ensures durability and high-performance. The base shape of the filter is thin lens, which is designed to minimize optical aberrations and distortions, thereby enhancing the overall quality of the output.
The physical data of the filter is equally impressive. It has a cut-on wavelength of 247.75nm and a cut-off wavelength of 249.45nm, with a central wavelength (CWL) of 248.6nm. This precise wavelength control ensures that the filter effectively blocks unwanted light and allows only the desired wavelength to pass through.
The coating on both the front and back of the filter is Sem LL01-248. This coating is designed to enhance the filter's performance and durability, ensuring that it can withstand the rigors of regular use.
