Semrock Inc., a unit of Idex Corp. based in Rochester, N.Y., has introduced a new website to accommodate online shopping and to facilitate filter and set selection. The portal offers updated customer service. In the OEM section, manufacturers can submit their specifications for a custom volume run, or select a catalog solution from the company’s range of optical filters. The website includes white papers, technical notes and reprints of journal articles. Pages on new applications and growing technologies are posted by on-staff optics experts, along with archived copies of the company’s imaging newsletter Wavelengths. Semrock manufactures optical filters for the biotech and analytical instrumentation industries and for more general laser and optical systems applications.
