Custom Optics & Capabilities Resources Use our helpful tools, guides, videos and other resources to solve your optical design challenges. Controlling light for image and beam manipulation requires meticulous attention to angular precision, surface quality, and material selection. 6mm - 100mm Prototypes to volume production High-precision optical machining Broad range of materials including optical glass (Schott, Ohara, Hoya, CDGM), fused silica, fused quartz, filter glass, and float glass. Applications for Prisms & Beam Splitters Binoculars Telescopes Ophthalmology Microscopy Fabrication begins with a LaCroix Manufacturing Engineer dedicated to seeing your project from sketch to completion. We follow a step-by-step process with rigorous quality checks along the way 1. Optical Design Our engineering team will collaborate with you and provide suggestions for making your optics manufacturable. 2. Shaping, Grinding As the shape takes form through generation, fine grinding forms the prism to your specifications. 3. Polishing, Cementing, Finishing Prism surfaces are polished and cemented together, and are ready for coating and metrology as needed. Optical Coatings from UV-SWIR Use our extensive in-house coating capabilities to meet your requirements. We've developed a variety of resources to help you determine the best optics for your application. Explore our full library of resources. Copyright © 2026, LaCroix Precision Optics
