Bandpass filter
Nearly 50 years of experience in coating processes and the new Magnetron Sputtering Technology combined with Japanese discipline, enables such outstanding specifications in all types of filters.
Product features:
These bandpass filters with their steep edges, the safe blocking of undesired wavelengths and the high transmission values in the passbands allow the user a kind of monochromatic resolution of his spectrum.
If, for example, intensities are not sufficient, wider passbands can be selected. ASAHI Spectra offers a standard FWHM of 10nm but at many central wavelengths also other bandwidths like 20, 40, 60, 80… up to 320nm.
Special UV high transmission filter:
Especially worth mentioning are the UV High-Transmission-Bandpass-Filter (XHQA), which have significantly higher transmission values in UV and are also particularly suitable for use with the MAX-350 illumination instrument.
