Our Sputtered Single Band Laser filter sets employ the same high-transmission, high-durability coatings as our other ET sets. These sets reflect a single wavelength range and consist of longpass transmission dichroics, laser clean-up filters and laser emission filters. In addition, all laser sets feature our Ultra-Flat laser dichroics. Chroma has developed a proprietary manufacturing method which minimizes surface curvature, and all of our laser dichroics with 1mm thick substrates are <2 lambda/inch Peak-Valley surface flatness. For more demanding applications such as TIRF, STED, structured illumination or PALM/STORM, we recommend our thicker dichroics mounted into Chroma’s custom metal cubes. Our manufacturing process, coupled with thicker substrates, provides the highest level of surface flatness in the industry for imaging dichroics used in microscope cubes.
