The 47-page full-color “2007 Catalog” from Semrock Inc. details optical filters for biotechnology and analytical instrumentation, including the BrightLine fluorescence filters, among them the single- and multiband sets; the UV, bandpass and multiphoton varieties; and the Clinical filter sets for microscopy. The catalog presents the RazorEdge Raman filters with laser lines ranging from 248 to 1064 nm, the MaxLine laser-line filters with steep edges and high laser-line transmission, the StopLine single- and multinotch deep laser-blocking filters and the MaxMirror ultrabroadband laser mirror with a wavelength range of 350 to 1100 nm. Charts and diagrams are included, along with technical notes on topics such as measuring light with wavelengths and wave numbers.
