Unlike a conventional spherical lens, a "cylinder lens" has curvature along only one axis. The figure shows an example of a plano-convex cylindrical lens, which brings parallel rays to a line focus.Read More >
Increased tariffs of 25% were recently announced with little advance notice on many items, including optics, coming into the United States from China. We are already feeling the impact on many of our products and will, unfortunately, be enacting a price increase to help offset the new tariffs. This increase will affect future quotes and some current recurring orders. We will get in touch with any customers who will be affected by this change to share the specifics of this increase on any existing orders. Read More >
Ideally, your optics are kept pristine and no cleaning is necessary-- but the reality is that almost all optics will require cleaning at some point. Optics are like pets, when it comes to maintenance: each one has its own unique characteristics and issues. The first step is to ensure you have a clean, contaminant free work surface such as a tray or hard surface table. Next, use only clean, powder-free gloves or finger cots. Always handle optics by the edges to avoid contaminating or damaging the lens surface.Read More >
The International Traffic in Arms Regulations (ITAR) exist to control access to sensitive, defense-related technology. It is obvious that companies working directly in the defense industry must understand ITAR, but it is equally important for companies that supply or subcontract sub-components, software, or services to defense-related products. Keeping up with ITAR is challenging for small companies with limited resources, because the regulations are dynamic and can change over time.Read More >

A frequent question posed to optical suppliers and manufacturers is: “What is the difference between Root Mean Square (RMS) and Peak-to-Valley (P-V)?” RMS and P-V are both methods for describing how well the shape of an object matches its designed curvature, called “surface figure" and "surface roughness," respectively. An understanding of RMS and P-V is critical in order to prevent over- or under-specifying the parts of an optical system.Read More >
