4Lasers provide uncoated flat-parallel windows, flat-wedge windows, and curved windows fabricated from UVFS and BK7 optical glasses for UV, VIS, and NIR applications. These optical components are the substrates of mirrors, output couplers, and beamsplitters in any kind of laser and non-laser systems. They are initially uncoated and demand metallic or dielectric coatings for a particular application. 4Lasers provide coating service upon request. Contact us for custom solutions and pricing.
